Referring to fig. 1 to 3, fig. 1 is a schematic view of a wall-mounted air conditioning indoor unit 1 according to an embodiment of the present utility model, fig. 2 is an exploded view of a duct skeleton 20, an evaporator 30, and a cross flow fan 40 in the wall-mounted air conditioning indoor unit 1 according to an embodiment of the present utility model, and fig. 3 is an exploded view of a front panel 50, a casing 10, and the duct skeleton 20 in the wall-mounted air conditioning indoor unit 1 according to an embodiment of the present utility model.
The present utility model provides a wall-mounted air conditioner indoor unit 1, and the wall-mounted air conditioner indoor unit 1 may generally include a housing 10, an air duct frame 20, an evaporator 30, a cross-flow fan 40, and a front panel 50.
The casing 10 protects the whole wall-mounted air conditioner indoor unit 1, an air inlet grille 110 is arranged at the top of the casing 10, a heat exchange airflow inlet 12 is formed on the air inlet grille 110, and a heat exchange airflow outlet 14 which is open towards the front and the lower side is arranged below the front side of the casing 10.
The air duct frame 20 is disposed inside the casing 10, a heat exchange air duct 222 extending in a lateral direction is formed on the air duct frame 20, and the heat exchange air duct 222 has an air inlet side opened toward the heat exchange air flow inlet 12 and an air outlet side opened toward the heat exchange air flow outlet 14. An air outlet duct 224 connected between the air outlet side of the heat exchange duct 222 and the heat exchange airflow outlet 14 is defined at the front lower side of the duct skeleton 20, so that the heat exchange airflow in the heat exchange duct 222 is guided to the heat exchange airflow outlet 14 through the air outlet duct 224.
Referring to fig. 4 and 5, fig. 4 is a sectional view of an indoor unit of a wall-mounted air conditioner in a closed state of an air guide plate according to an embodiment of the present utility model, and fig. 5 is a sectional view of an indoor unit of a wall-mounted air conditioner in an open state of an air guide plate according to an embodiment of the present utility model.
Specifically, the interior of the duct skeleton 20 has upper and lower duct walls 226, 228 disposed in spaced apart relation to define an outlet duct 224. And the front end of the upper duct wall 226 is more forward than the front end of the lower duct wall 228 so that the outlet of the outlet duct 224 is also opened toward the front lower side so that the front ends of the upper duct wall 226 and the lower duct wall 228 meet the upper and lower ends of the heat exchange air flow outlet 14, respectively.
The evaporator 30 is installed on the air duct frame 20 and covers the heat exchange air duct 222 to exchange heat with air sucked into the housing 10 from the heat exchange air inlet 12, and the heat exchanged air is discharged into the room through the air outlet side of the air duct frame 20 and the heat exchange air outlet 14 of the housing 10, thereby realizing refrigeration or heating.
The cross flow fan 40 is installed in the heat exchange duct 222 in a lateral direction for inducing indoor air flow into the casing 10 from the heat exchange air flow inlet 12 to exchange heat with the evaporator 30 and finally discharged from the heat exchange air flow outlet 14.
The front panel 50 is detachably fixed to the front side of the casing 10 to function as a decoration and protection for the wall-mounted air conditioner indoor unit 1.
Referring to fig. 4 and 5, in some embodiments, the upper end of the heat exchange gas flow outlet 14 is further rearward than the front wall of the casing 10, and the front panel 50 may further include a main body plate section 52 and a flow guiding plate section 54, the main body plate section 52 being disposed at the front side of the casing 10, the flow guiding plate section 54 being connected between the lower end of the main body plate section 52 and the upper end of the heat exchange gas flow outlet 14, and the flow guiding plate section 54 being disposed as a circular arc panel protruding toward the front.
According to the coanda effect, the fluid changes from deviating from the original flow direction to a tendency to flow with a convex object surface. When there is surface friction between the fluid and the surface of the object over which it flows, the fluid will flow along the surface of the object as long as the curvature is not large.
In this embodiment, since the flow guiding plate section 54 is connected between the lower end of the main body plate section 52 and the upper end of the heat exchange airflow outlet 14, the flow guiding plate section 54 is arranged to be a front convex arc panel, so that the heat exchange airflow discharged near the upper end of the heat exchange airflow outlet 14 is discharged upwards along with the flow guiding plate section 54, so that the front panel 50 also has a flow guiding function, and further the air supply airflow is more uniform and soft, and the experience of the user is improved. Particularly, when the air conditioner refrigerates, the user can be avoided by upward blowing of air, and the direct blowing prevention effect is achieved.
Further, the axis of the flow-guiding plate section 54 is parallel to the lateral direction of the housing 10, and the radius of the flow-guiding plate section 54 is arranged between 13cm and 20cm, such as 13cm, 18cm, 20cm, etc.
Since the flow-directing plate segment 54 is a circular arc panel, the radius of the circular arc panel is inversely proportional to its curvature, the greater the radius, the smaller the curvature, and the less the degree of curvature. The curvature of the flow guiding plate section 54 is not excessively large by the above limitation, so that the phenomenon that the wall attaching effect of the heat exchange air flow is not obvious due to the excessively large curvature is avoided.
Further, the main body plate section 52 is vertically arranged, and the tangential direction of the upper end of the drainage plate section 54 is in a vertical direction, so that the drainage plate section 54 and the main body plate section 52 are in smooth transition.
Referring to fig. 4 and 5, in some embodiments, the lower duct wall 228 of the duct skeleton 20 may further include a main body section 228a and a turn section 228b, with the air inlet end of the turn section 228b being connected to the air outlet end of the main body section 228 a.
The air outlet direction of the air outlet end of the main body section 228a is forward and downward, and the air inlet direction of the air inlet end of the turning section 228b is more downward than the air outlet direction of the air outlet end of the main body section 228a, so that the heat exchange air flow is led out downwards along the turning section 228b after flowing out from the main body section 228 a.
In this embodiment, since the lower duct wall 228 of the duct skeleton 20 is provided with the main body section 228a and the turn, the heat exchange air flows downward along the turn section 228b after flowing out from the main body section 228 a. According to the coanda effect of a fluid, when there is surface friction between the surfaces of an object over which it flows, the fluid will flow along the surfaces of the object as long as the curvature is not large. Thus, in this embodiment, although the direction of the turn section 228b has an angular downward turn compared to the body section 228a, the airflow will continue to flow along the surface of the turn section 228b due to the viscosity. This allows the air flow to have a downward turn in the direction of the air flow, thus more closely approximating a vertically downward direction, to facilitate a direct ground. Particularly when the air conditioner heats, the foot warming experience can be realized by blowing the air downwards.
Referring to fig. 5, further, the turning section 228b is in the shape of a circular arc with its axis parallel to the lateral direction of the casing 10, and the included angle θ between the air outlet direction of the main body section 228a and the air inlet direction of the turning section 228b is between 25 ° and 35 °, such as 25 °, 30 °, 35 °, etc.
In some embodiments, the main body section 228a of the lower duct wall 228 may be understood as a conventional volute and extends smoothly, the air outlet direction of the main body section 228a is the tangential direction of the air outlet end of the main body section 228a, the air inlet end of the turning section 228b is connected to the air outlet end of the main body section 228a, and the air inlet direction of the turning section 228b is the tangential direction of the air inlet end of the turning section 228 b.
By specifically limiting the angle between the air outlet direction of the main section 228a and the air inlet direction of the turning section 228b, an optimal "wind direction turning" effect can be achieved. That is, the angle at which the turning section 228b is bent is made larger, so that the angle at which the wind direction turns is made larger, closer to the vertically downward direction; meanwhile, a strong coanda effect is ensured, so that the situation that the airflow cannot be well attached to the surface of the turning section 228b due to the fact that the bending angle of the turning section 228b is too large is avoided, and the total amount of airflow which is finally turned is too small.
Further, the radius of the turning section 228b is set to be between 5cm and 15cm, for example 5cm, 10cm, 15cm. Likewise, by specifically limiting the radius of the turning segment 228b, it is ensured that the turning segment 228b itself does not have too great a curvature, resulting in a better attachment of the heat exchange air stream thereto.
Further, the angle between the air outlet direction of the turning section 228b and the vertical direction is between 0 ° and 15 °, that is, when the angle between the tangential direction of the air outlet end of the turning section 228b and the vertical direction is between 0 ° and 15 °, so as to determine the direction of the heat exchange air flow discharged from the turning section 228 b.
In some embodiments, the wall-mounted air conditioner indoor unit 1 may further include an air deflector 60, where the air deflector 60 may be disposed at the heat exchange air flow outlet 14 around a rotation axis to open and close the heat exchange air flow outlet 14.
Specifically, the axis of rotation x of the deflector 60 is parallel to the lateral direction of the housing 10 and is located rearward of the lower end of the heat exchange air flow outlet 14.
When the air deflector 60 closes the heat exchange air flow outlet 14, the first and second ends of the air deflector 60 are connected to the upper and lower ends of the heat exchange air flow outlet 14, respectively. When the air deflector 60 opens the heat exchange airflow outlet 14, the second end of the air deflector 60 gradually rotates to the rear lower side of the lower end of the heat exchange airflow outlet 14, that is, the lower end of the heat exchange airflow outlet 14 may face the air guiding surface of the air deflector 60 (the surface of the air deflector 60 closing the heat exchange airflow outlet 14 and facing the inside of the air outlet duct 224), so that the heat exchange airflow is guided by the air deflector 60.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model.
