An indoor unit of a wall-mounted type air conditioner is an indoor part of a split wall-mounted type room air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like.

Fig. 1 is a schematic structural view of a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention; fig. 2 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 1 with the movable panel pivoted to a down-blowing position; fig. 3 is a schematic enlarged view of the inner guide plate in fig. 1.

As shown in fig. 1 to 3, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a cabinet 10, a movable panel 20, and an inner guide 30.

The casing 10 is opened with a front outlet 12 opened forward and a lower outlet 13 opened downward. The cabinet 10 defines an accommodation space for accommodating components of a wall-mounted air conditioning indoor unit. The front air outlet 12 is opened at the lower part of the front side of the casing 10, and the lower air outlet 13 is opened at the front part of the bottom side of the casing 10. The front outlet 12 and the lower outlet 13 are used for discharging airflow in the cabinet 10 to the indoor environment to condition indoor air. The discharged air flow is referred to as air flow which is acted on by the fan 40 in the cabinet 10 to accelerate the air flow passing through the front air outlet 12 and the lower air outlet 13 for adjusting the indoor environment, such as cold air in a cooling mode, hot air in a heating mode, fresh air in a fresh air mode, and the like. The casing 10 may be a long strip with a length direction horizontally arranged, and the front air outlet 12 and the lower air outlet 13 may be long strips with a length direction parallel to the length direction of the casing 10.

One end of the movable panel 20 is rotatably mounted to the casing 10, and the rotation axis x is located at a separation (or a junction) between the front air outlet 12 and the lower air outlet 13. The rotation axis x of the movable panel 20 is parallel to the length direction of the cabinet 10. The movable panel 20 is configured to be in a blowing-down position for shielding the front air outlet 12 to expose the lower air outlet 13, as shown in fig. 3; or from the downward blowing position to the forward blowing position (i.e. first forward rotating to horizontal state, then backward rotating) for shielding the lower outlet 13 and exposing the front outlet 12. Of course, the blow-down position and the blow-forward position are only two limit positions at which the movable panel 20 is reciprocally translated up and down, and the movable panel 20 may be stopped in any state therebetween, as shown in fig. 5. It is to be understood that the movable panel 20 also passes through the space outside the cabinet 10 when returning from the forward blowing position to the downward blowing position.

The front blowing mode can be selected when the air conditioner refrigerates, so that the air supply distance of cold air is longer, and then the cold air gradually sinks to form a shower type refrigerating effect. The down blowing mode can be selected when the air conditioner heats, so that hot air can reach the ground more easily, the carpet type air supply effect is realized, and the problem that the indoor bottom space cannot be heated due to the fact that the hot air cannot reach the ground due to low density is avoided. The wall-mounted air conditioner indoor unit provided by the embodiment of the utility model can select different air supply modes during refrigeration and heating, so that the air supply direction is more matched with the special requirements of refrigeration and heating, and the design is very ingenious.

The inner guide 30 is rotatably disposed inside the housing 10, and has a first end (M end) and a second end (N end) at two ends in the width direction. The inner guide 30 is elongated with its longitudinal direction parallel to the longitudinal direction of the housing 10, and its rotational axis y is parallel to its longitudinal direction. The two air guiding surfaces (two large planes) of the inner guide plate 30 are a first side surface 311 and a second side surface 312. A section of the inner guide plate adjacent to the first end (M end) is bent toward the side of the first side surface 311, so that when the inner guide plate 30 is in a front wind guiding position where the first end (M end) faces forward and the first side surface 311 faces upward, the airflow is guided upward by the bent portion. In this way, when the movable panel 20 is in the forward blowing position, the inner guide 30 can be rotated to the forward blowing position, as shown in fig. 1, so as to guide the airflow upward and make the airflow upward angle larger. When the movable panel 20 is in the down-blowing position. The air flow can be directed downward by means of an inner guide plate 30, fig. 2. In summary, the embodiment of the present invention utilizes the inner guide plate 30 to cooperate with the movable panel 20, so as to achieve better forward blowing effect and downward blowing effect.

In some embodiments, as shown in fig. 3, the first side 311 includes a first arc segment AB and a second arc segment BC connected with each other in the extending direction from the second end (N end) to the first end (M end), and the two arc segments are concave outwards and concave inwards and smoothly connected with each other. The second side 312 includes a third curved segment DH and a fourth curved segment HK that are joined, convex side-out, convex and smooth. In this way, the transition between the rear main body section and the front curved section of the inner guide plate 30 is made more gradual, and the line type of the first side 311 and the second side 312 is made more reasonable, so that the flow resistance of the air flow is made smaller.

In particular, the ratio of the radii of the second curved segment BC to the first curved segment AB is between 0.2 and 0.5, preferably between 0.3 and 0.4, and the ratio of the radii of the fourth curved segment HK to the third curved segment DH is between 0.1 and 0.4, preferably between 0.2 and 0.3. Through the design, the line type of the first side 311 and the second side 312 is more reasonable, so that the flow resistance of the airflow is smaller.

As shown in fig. 2, when the movable panel 20 is in the downward blowing state, the outer surface thereof is flush with the front surface of the cabinet 10 to form an appearance effect of complete abutment with the cabinet 10. When the wall-mounted air conditioner indoor unit is in a non-operating state, the movable panel 20 can be in this state, so that the wall-mounted air conditioner indoor unit is more attractive in appearance. Further, as shown in fig. 1, when the movable panel 20 is in the forward blowing state, the outer surface thereof is flush with the bottom surface of the casing 10, so that the bottom appearance of the wall-mounted air conditioning indoor unit is more beautiful.

In some embodiments, as shown in fig. 1 and 2, the casing 10 has an air duct 50 therein, and the air duct 50 is defined by a front air duct wall 200 and a rear air duct wall 100 which are spaced apart from each other in the front-rear direction. The outlet ends of the front duct wall 200 and the rear duct wall 100 are respectively connected to the upper end of the front air outlet 12 and the rear end of the lower air outlet 13, so as to guide the air flow in the cabinet 10 to the air outlet 12. An air inlet 11 is formed at the top of the casing 10, and a cross flow fan 40 having an axis extending in a transverse direction is disposed at an inlet of the air duct 50. The three-stage heat exchanger 60 surrounds the crossflow blower 40. When the wall-mounted air conditioner indoor unit operates in a cooling mode or a heating mode, indoor air enters the interior of the casing 10 through the air inlet 11, exchanges heat with the three-section heat exchanger 60, is finally sucked into the air duct 50 by the cross-flow fan 40, and flows towards the front air outlet 12 and the lower air outlet 13.

Further, as shown in fig. 1, the front duct wall 200 may specifically include a volute tongue section EF, a connecting section FG, and a rising section GJ. The front end of the volute tongue section EF constitutes the inlet end of the front duct wall 200, and extends from the front upper side toward the rear lower side. The connecting section FG extends forward and downward from the rear end of the volute tongue section EF. The rising section GJ extends forward and upward from the rear end of the connection section FG, and the front end thereof constitutes the outlet end of the front duct wall 200, preferably with the elevation angle θ of the rising section between 10 ° and 15 °. Because the front air duct wall 200 is provided with the upward section GJ, enough space is reserved for upward air flow, and the upward air flow is favorably blown out.

Fig. 4 is a schematic view of the wall-mounted air conditioning indoor unit shown in fig. 1 when the inner guide plate is rotated to the down-wind guiding position.

In some embodiments, the inner guide plate 30 is configured to: when the movable panel 20 is in the down-blowing position, it can be rotated to a down-wind guiding position where the first end (M end) faces forward and downward, the second end (N end) is adjacent to the front air duct wall 200, and the second side 312 faces backward and downward, as shown in fig. 2. Thus, the airflow is more smoothly guided to the inner guide 30 and then guided to the movable panel 20 by the inner guide 30, and both the changes of the direction of the airflow are very gentle in the process, so that the wind loss is less. At the same time, the air flow is prevented from flowing to the region at the corner between the movable panel 20 and the front duct wall 200, and the generation of vortex flow at the position is prevented, resulting in less noise.

As shown in fig. 4, the inner guide 30 is further configured to be rotated to a lower air guiding position where the first end (M segment) faces upward and forward and is adjacent to the front air duct wall 200 and the first side face faces downward and rearward when the movable panel 20 is in the forward blowing position, so as to guide the air flow downward and forward.

In order to enable the inner guide plate 30 to rotate to the specific positions, as shown in fig. 1, the rotation axis y of the inner guide plate 30 is located at the side of the first side surface 311, spaced from the first side surface 311, and the projection of the first side surface 311 is close to the first end M and close to the air outlet section of the front air outlet 12.

Fig. 5 is a schematic view of the wall-mounted air conditioning indoor unit shown in fig. 1 when the movable panel is rotated to a high airflow position.

As shown in fig. 5, the movable panel 20 is further configured to: the movable panel 20 can be rotated to a high air volume position in the outer space of the casing 10 to simultaneously open the front outlet 12 and the lower outlet 13, so that the air flow in the casing 10 can flow out more smoothly. In this case, the movable panel 20 also has the air guide effect.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the utility model may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the utility model.
