Aiming at the technical problem, the invention provides a technical scheme for additionally arranging the drainage part 400. The method comprises the following specific steps: the drainage part 400 is provided between and below the air blowing ports 110, and includes a first drainage part and a second drainage part, wherein,
the first guiding portion includes at least one first guiding groove 410, and the forming process of the first guiding groove 410 is performed simultaneously with the forming process of the casing 100, that is, the forming process of the casing 100 is obtained by deformation. The first air guide groove 410 is formed by a gap formed by the air blowing opening 110 to allow the indoor air at the rear of the casing 100 to flow to the air blowing opening 110 through the first air guide groove 410, and to be mixed with the heat-exchanging air to form mixed air to be blown into the room again.
The second air guiding groove 430 is formed by a gap formed by the air supply opening 110, so as to allow indoor air behind the casing 100 to flow to the air supply opening 110 through the second air guiding groove 430, and mixed with heat exchange air to form mixed air to be blown into the room again, thereby realizing diversification of air mixing directions and further homogenizing the mixed air.
The first air guide groove 410 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 air guide flow. During air conditioner refrigeration, the drainage air current alternate of interval department is inside cold air current wind post, mixes wind and temperature exchange at the inside direct wind that carries on of wind post to form cold and not cold even mixed wind post of mixing wind, owing to its interval department forms powerful negative pressure, can form the fast-speed drainage air current of the big amount of wind, so, the technical scheme of this embodiment not only can realize cold and hot air current alternate intensive mixing, can promote the drainage volume simultaneously greatly, thereby promote the cool and not cold comfortable air supply of user and experience.
The second flow guiding part comprises a flow guiding plate 420, the length direction of the flow guiding plate 420 is transversely extended and arranged below the bottom of the casing 100, and a second flow guiding groove 430 is defined with the bottom of the casing 100, so that indoor air below the casing 100 is allowed to flow to the front of the air supply opening 110 through the second flow guiding groove 430 and is mixed with heat exchange air to form mixed flow to be blown into the room again.
A second guide groove 430 is added below the blowing port 110, and the heat exchange wind is sufficiently mixed with the indoor air in the main blowing direction.
As shown in fig. 4, the first air guiding groove 410 and the second air guiding groove 430 are communicated with each other, so that the indoor air is continuous when flowing, and the air supply is more uniform, and the air flow direction of the air guiding groove and the air supply opening 110 is visually shown in fig. 4.
The first induction groove 410 is positioned between the supply ports 110, and the third induction groove is positioned at the lower portion of the supply ports 110. The air inducing part is composed of a first air inducing groove 410 at the interval of the air outlet and a second air inducing groove 430 at the lower part of the air supply outlet 110, the first air inducing groove 410 and the second air inducing groove 430 are communicated with each other to form a plug-in type communicated full air inducing opening together, heat exchange airflow at the air supply outlet 110 forms a communicated negative pressure area in the peripheral area of each independent air supply outlet 110, for the whole indoor unit 10, the first air inducing groove 410 interrupts main airflow to form plug-in type air inducing, meanwhile, the second air inducing groove 430 is arranged below the air supply outlet 110 to form a complete communicated negative pressure area, the air inducing amount can be greatly increased, meanwhile, the air inducing area is increased, the air mixing uniformity is improved, and the real cool but not cool comfortable experience is brought to users.
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.
On the other hand, in order to better connect the flow guide plate 420 with the indoor unit 10, the wall-mounted air conditioning indoor unit 10 further includes connecting members 500 symmetrically disposed on both sides of the lower portion of the casing 100, wherein one end of each connecting member 500 is connected to the lower portion of the casing 100, and the other end is connected to the upper front portion of the flow guide plate 420.
The connecting member 500 is connected to a synchronous driving motor (not shown) at both ends, and the connecting member 500 drives the flow guide plate 420 to rotate around a rotation axis parallel to the transverse direction of the casing 100 and rotate synchronously with the air guide plate 600, so that the air guiding direction of the third air guiding groove is parallel to the air supplying direction of the air supplying opening 110.
In this embodiment, the air deflector 600 is preferably positioned such that the air induction direction of the second air induction groove 430 is parallel to the air blowing direction of the air blowing port 110. If the induced air direction of the second induced air groove 430 is not parallel or nearly parallel to the air supply direction of the air supply opening 110, the indoor induced air and the heat exchange air cannot be completely and uniformly mixed, stable air supply cannot be achieved, and good experience cannot be provided for the user.
To better serve the drainage function, the present invention designs the drainage plate 420 to be oval in cross-section with the major axis of the oval cross-section extending obliquely upward from front to back relative to the housing 100. In this way, the air in the rear lower portion of the casing 100 can flow obliquely upward along the narrow side of the oval shape and then flow obliquely downward along the wide side, so as to join the heat exchange air more smoothly. The appearance of the air conditioning indoor unit 10 is also made more beautiful.
In some preferred embodiments, the lateral width of the second guide groove 430 is greater than the sum of the lateral width of the first guide groove 410 and the lateral width of the supply opening 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 first air guide groove 410 to the transverse width of the air supply opening 110 is 1: 10-1: 5, the transverse width of the first air guide groove 410 is selected to make the heat exchange air from the air supply opening 110 account for most of the air supplied into the room, so as to ensure the stability of the indoor temperature, and further, a proper amount of indoor air is introduced to be mixed with the heat exchange air, so that the air supplied into the room is cool but not cold, the air is supplied gently, and the comfort level of a user is improved. Moreover, the longitudinal width of the second air guiding groove 430 is smaller than the longitudinal opening width of the air supply opening 110, so that the air guiding quantity of the second air guiding groove 430 is smaller than the heat exchange air from the air supply opening 110, the stability of the indoor temperature is ensured, and cool and not-cold air supply experience is provided for users.
In some preferred embodiments, the upper portion of the first guide groove 410 extends from the rear to the front along the casing 100 in an arc shape. Further, in the process of extending from the rear to the front, both side walls of the first air guide groove 410 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 first air guide groove 410 toward the air blowing opening 110 side.
In the forming process of the first air guide groove 410, the shape of the first air guide groove 410 is ensured to be arranged along the flowing direction of the air flow as much as possible, the upper part of the first air guide groove 410 extends in an arc shape, so that the air at the rear side of the indoor unit 10 can 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 first air guide groove 410, 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 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 guiding section is too short, a good air guiding effect cannot be achieved on the air flow, the air flow of the first air guiding groove 410 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.
In order to better achieve the air induction of the first air induction groove 410, the mechanical energy loss is minimized during the air induction process. In other embodiments, as shown in fig. 3, the bottom surface of the housing 100 includes: a horizontal section 130 extending forward from the rear end of the bottom of the casing 100, an inclined section 140 extending forward and upward from the front end of the horizontal section 130 to the lower edge of the blower port 110, and a baffle section 150 extending forward and downward from the front end of the inclined section 140 along the lower edge of the blower port 110. The distance from the front end of the deflecting section 150 to the front end of the upper edge of the air blowing opening 110 is equal to the longitudinal width of the air guide plate 600 of the indoor unit 10.
The indoor air flows along the bottom surface of the casing 100, and is turned after passing through the deflecting section 150 to be in accordance with the flow direction of the heat exchange air, thereby reducing noise generated when the indoor air and the heat exchange air are merged.
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.
