Where the orientations or positional relationships indicated by the terms "front," "back," "upper," "lower," "top," "bottom," "inner," "outer," "lateral," and the like are based on the orientations or positional relationships shown in the drawings, the description is for convenience only and to simplify the description, and no indication or suggestion is made that the device or element so indicated must have a particular orientation, be constructed and operated in a particular orientation, and is therefore not to be construed as limiting the invention.
As shown in fig. 1 to 4, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention generally includes a casing 100, an evaporator 900, a fan 800, an air duct 300, and two air outlets, which are an upper air outlet 120 and a lower air outlet 130. The wall-mounted air conditioning indoor unit and an air conditioning outdoor unit (not shown) constitute a vapor compression refrigeration cycle system, and realize cooling/heating of an indoor environment.
The fan is preferably a cross-flow fan 800 having an axial direction extending in a lateral direction (i.e., left-right direction as viewed in fig. 1) for causing air to flow from the evaporator 900 to the upper outlet port 120 or the lower outlet port 130 and then to be blown into the room.
The evaporator 900 is used for exchanging heat with air entering the housing 100 from the air inlet 110 to form heat-exchange air (specifically, cold air during cooling and hot air during heating). Evaporator 900 is preferably a three-section finned evaporator covering the space in front of and above crossflow blower 800.
The top of the housing 100 has an air inlet 110, and the air inlet 110 has an air inlet grille. The lower portion of the front side of the casing 100 is provided with the above-mentioned upper air outlet 120 and lower air outlet 130. The upper outlet 120 and the lower outlet 130 are arranged in the up-down direction. The upper outlet 120 is provided at an upper side and facing forward, and the lower outlet 130 is opened at a lower side and facing forward and downward. As shown in fig. 1, the housing 100 may be an elongated structure extending in the transverse direction (i.e., left-right direction). The upper outlet 120 and the lower outlet 130 are elongated openings extending in the transverse direction.
An air duct 300 is arranged in the casing 100, an inlet end of the air duct 300 is located at the cross flow fan 800, and an outlet end of the air duct 300 is located at the two air outlets. The air duct 300 is used to guide the heat-exchange air from the evaporator 900 to the air outlet, so that the air is blown out from the air outlet, thereby realizing cooling/heating of the indoor environment.
The front end of the baffle 500 is pivotally mounted to the housing 100 between the upper outlet 120 and the lower outlet 130, and the position of the pivot axis 510 is shown in fig. 2. The pivot axis 510 extends in a transverse direction.
Fig. 2 to 4 illustrate the wind direction with arrow lines. As shown in fig. 3 and 4, the baffle 500 may be pivoted upward to a downward blowing position in which the rear end of the baffle abuts against the upper wall of the air duct 300 to close the passage from the air duct 300 to the upper outlet 120, so that the air can be blown out from the lower outlet 130 only. As shown in fig. 2, the deflector 500 may also be pivoted downward to an upward blowing position in which the rear end of the deflector abuts against the lower wall of the air duct 300, so as to close the passage from the air duct 300 to the lower outlet 130, and allow the air to be blown out from the upper outlet 120 only.
Specifically, the air duct 300 is composed of an upper volute 320 and a lower volute 310, the inner wall of the lower volute 310 is the lower wall of the air duct 300, and the inner wall of the upper volute 320 is the upper wall of the air duct 300. With the baffle 500 in the aforementioned up-blowing position, the rear end thereof may be made to abut against the front edge of the lower volute 310. The upper volute 320 has a volute tongue 321, and when the guide plate 500 is at the downward blowing position, the rear end of the guide plate abuts against the volute tongue 321, so that after the guide plate 500 and the lower volute 310 form a new air duct together, the upper wall of the new air duct forms a complete volute profile again, the wind direction meets the flow direction requirement of the cross flow fan 800, and the fan efficiency is improved.
As shown in fig. 2 to 5, the lower edge of the upper outlet 120 extends backward to form a first arc plate AC, and the axis (the O axis extending in the transverse direction) thereof is located at the rear upper part thereof. A second arc plate BK is extended from the front upper surface of the baffle 500 with its axis located at the rear upper side. When the guide plate 500 is located at the upward blowing position, the point C at the end of the first arc plate AC is connected with the point K at the end of the second arc plate BK, and the axes of the first arc plate AC and the second arc plate BK are overlapped (both are O-axis), so that the two arc plates form an arc plate with a larger central angle.
In this embodiment, the edge of going up air outlet 120 and the front end of guide plate 500 adopt two circular arc boards to link to each other, and the transition is more level and smooth, can avoid producing the vortex at both junctions with leading more smoothly to supreme air outlet 120, reduces the pressure loss, reduces windage, the loss of amount of wind.
Further, as shown in fig. 5, in order to make the connection between the second arc segment BK and the flow guide plate 500 more gradual, the starting end of the second arc plate BK may be tangent to the flow guide plate 500, and the tangent point is point B.
Further, as shown in fig. 6, a rear portion of the end (C end) of the first arc segment AC may be extended downward by a rib 170. When the baffle 500 is in the upblow position, the tip (K-tip) of the second circular arc segment BK abuts against the front side of the rib 170. So that the seal between the two is tighter and does not prevent the baffle 500 from pivoting upward.
In some embodiments, the upper surface of the rear portion of the air deflector 500 and the front portion of the lower wall 310 of the air duct 300 are both curved surfaces, and when the air deflector 500 is located at the upward blowing position, the upper surface of the rear portion thereof is smoothly connected with the lower wall 310 of the air duct 300, so that the air flow passing through the air deflector can smoothly flow through the air deflector, the buffering effect is achieved, the vortex is avoided, and the air volume loss is reduced.
As shown in fig. 2 and 5, when the guiding plate 500 rotates to the up-blowing position, the GF section of the bottom wall 310 of the air duct 300, the ED section of the guiding plate 500, the flat-plate DB section, the second arc section BK, and the first arc section AC are sequentially connected to smoothly guide the air to the upper outlet 120 together with the top wall of the air duct 300, so that the loss is small. The wind is blown out obliquely forward and upward.
Specifically, for example, as shown in fig. 5, when the guide plate 500 is in the upward blowing position, the rear BK segment of the guide plate 500 is connected to the FG segment at the front end of the lower wall 310 of the air duct 300, so that the DG segments together form a circular involute surface.
The forming process of the involute is not repeated herein, and as shown in fig. 7, the radius of the base circle of the involute is r, and a coordinate system is established by taking the center of the base circle as an origin, so that a parameter equation of the involute can be obtained, wherein x is r (sin β - β cos β), Y is r (cos β + β sin β), and β is an included angle between a connecting line of a fixed point E and the center of the circle and a Y axis, wherein r is more than or equal to 15mm and less than or equal to 30mm, preferably 24, β is more than or equal to 210 degrees and less than or equal to 270 degrees, and preferably more than or equal to 230 degrees and less than or equal to β and less than.
Referring to fig. 5, assuming that the width of the baffle 500 is l (BK), the distance l (hk) from the beginning K of the second arc segment BK to the front H of the baffle 500 preferably satisfies the following relationship:
0.2*L(BK)≤L(HK)≤0.4*L(BK)。
in some embodiments, as shown in fig. 3 and 4, when the baffle 500 is in the aforementioned down-blowing position, the baffle 500 and the lower wall of the wind tunnel 300 are both extended to be gradually inclined downward from back to front, so that the wind is inclined downward from front to front. As shown in fig. 2, when the baffle 500 is in the above-mentioned upward blowing position, the baffle 500 and the upper wall of the air duct 300 are both inclined upward from the rear to the front, so that the wind direction is inclined upward from the front.
In some embodiments, as shown in fig. 1 to 4, a wind deflector 200 is disposed at the lower wind outlet 130. The air guiding plate 200 is configured to be rotatable around a transverse axis to adjust the upward and downward air outlet directions of the lower air outlet 130. In addition, when the flow guiding plate 500 is located at the above-mentioned upward blowing position, the air guiding plate 200 is located outside the flow guiding plate 500, so that when the lower air outlet 130 is not needed for air supply, the air guiding plate 200 seals the lower air outlet 130, as shown in fig. 1 and fig. 2, the bottom appearance of the indoor unit of the air conditioner is more beautiful.
When the guide plate 500 is located at the upward blowing position or the downward blowing position, the front end of the guide plate needs to be well sealed with the inner wall of the casing 100 to avoid air leakage, noise generation, condensation and other problems. However, if only the sealing performance is considered, the gap between the front end of the baffle 500 and the inner wall of the casing 100 is designed to be too small, which may cause the baffle 500 to rotate hard or even to be jammed.
To this end, in some preferred embodiments, as shown in fig. 5, the portion of the inner wall of the casing 100 near the front end of the baffle 500 is an arc surface 150, the arc surface 150 is coaxial with the pivot 510 of the baffle 500, and when the baffle 500 rotates, the front end (rotating around the pivot 510) of the baffle 500 slides against the arc surface 150, so that the seal between the baffle 500 and the inner wall of the casing 100 is good and no jamming occurs.
In some embodiments, as shown in fig. 2 to 4, a plurality of air guiding flaps 400 are installed at the lower wall of the air duct 300, and the plurality of air guiding flaps 400 are arranged in the transverse direction and configured to rotatably adjust the left and right air outlet directions of the upper air outlet 120 and the lower air outlet 130, so as to guide the air to the left or the right. The air guide swing blade is widely used in the existing wall-mounted air conditioner indoor unit, and the specific structure of the air guide swing blade is not described again.
In some embodiments, an air outlet grille is disposed at the upper air outlet 120. The upper air outlet 120 is more beautiful due to the arrangement of the air outlet grille. Meanwhile, the air outlet grille can be configured to enable the air to pass through and then be blown obliquely forwards and upwards, so that the air outlet grille has the function of guiding the wind direction.
The wall-mounted air conditioner indoor unit provided by the embodiment of the invention can realize multiple air supply modes:
(1) no blowing mode. As shown in fig. 2, the baffle 500 is in the up-blow position. At the moment, wind is blown out in an upward mode, the user cannot be blown out, the refrigerating/heating performance cannot be influenced, the air supply effect of people cannot be blown out, discomfort caused by direct blowing of the user is avoided, and the wind feeling experience of the user is improved. When the air conditioner is used for refrigerating or heating, the mode of blowing no people can be adopted.
(2) A powerful heating mode. As shown in fig. 3, the baffle 500 is in the down-blowing position, and the air deflector 200 directs the wind downward such that the wind blows straight downward. Because the density of the hot air is low and the hot air has an ascending trend, the hot air is blown downwards as much as possible, and the heating effect can be enhanced.
(3) A forced cooling mode. As shown in fig. 4, the air guide plate 500 is in the downward blowing position, and the air guide plate 200 guides the air forward, so that the air blows forward, and the cold air is blown upward as much as possible due to the sinking tendency of the cold air with high density, thereby enhancing the cooling effect.
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. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
