DETAILED DESCRIPTION OF THE EMBODIMENTS

The technical solutions of the embodiments of the present disclosure will be clearly and completely described in the following with reference to the accompanying drawings. It is obvious that the embodiments to be described are only a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by persons skilled in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.
It is to be understood that, all of the directional instructions in the embodiments of the present disclosure (such as top, bottom, left, right, front, rear...) can only be used for explaining relative position relations, moving condition of the elements under a special form (referring to figures), and so on, if the special form changes, the directional instructions changes accordingly.
In addition, the descriptions, such as the "first", the "second" in the embodiment of present disclosure, can only be used for describing the aim of description, and cannot be understood as indicating or suggesting relative importance or impliedly indicating the number of the indicated technical character. Therefore, the character indicated by the "first", the "second" can express or impliedly include at least one character. Besides, the technical solution of each embodiment can be combined with each other, however the technical solution must base on that the ordinary skill in that art can realize the technical solution, when the combination of the technical solutions is contradictory or cannot be realized, it should consider that the combination of the technical solutions does not exist, and is beyond the protection scope of the present disclosure.
The present disclosure provides a wall-mounted indoor unit. The wall-mounted indoor unit can simplify the assembly manner to reduce the assembly difficulty, thereby improving the production efficiency of the wall-mounted indoor unit.
Referring to FIG. 1 to FIG. 3, the wall-mounted indoor unit of the present disclosure includes a housing. The housing includes a face frame 10, an end plate 20, and an end cover 30. The end plate 20 is located at an end of the face frame 10, and integrated with the face frame 10. The end cover 30 is mounted at the end of the face frame 10 and covering the end plate 20.
Specially, the housing includes a chassis, a face frame 10, a front panel, an end plate 20, and an end cover 30. The face frame 10 is mounted on the chassis, and the front panel is mounted on the face frame 10. An air inlet is defined in a top of the face frame 10, and an air outlet is defined in a bottom of the face frame 10. The end plate 20 is located at an end of the face frame 10 and is integrated with the face frame 10. The end cover 30 is mounted on the face frame 10 and covers the end plate 20 of the face frame 10.
Since the face frame 10 is integrated with the end plate 20, during the assembly process, it is only necessary to integrally mount the face frame 10 and the end plate 20 to the chassis, and then cover the end cover 30 to the end plate 20. Besides, since the face frame 10 is integrated with the end plate 20, due to the limitation of the production molding conditions, the surface of the end plate 20 may be poorly decorated, and is not sufficient as the end surface of the wall-mounted indoor unit. Therefore, by covering the end plate 20 with the end cover 30, the outer surface of the end cover 30 and the outer surface of the face frame 10 are connected to be a relatively complete surface, thereby improving the overall integrity of the wall-mounted indoor unit.
The wall-mounted indoor unit further includes a heat exchanger and a cross-flow wind turbine (not shown), the heat exchanger and the cross-flow wind turbine being mounted in the housing. When the wall-mounted indoor unit is in operation, under the driving of the cross-flow wind turbine, the air enters the inside of the housing from the air inlet. This part of the air forms a blast air after the air is exchanged by the heat exchanger, and finally the blast air is blown forward from the air outlet to the room to realize indoor cooling or heating.
In the technical solutions of the present disclosure, the face frame 10 is integrated with the end plate 20 to disassemble the face frame 10 and the end plate 20 as a whole during assembly, and finally the cover plate 20 is covered by the end cover 30. As such, the method for assembling the wall-mounted indoor unit is relatively simple, which effectively reduces the assembly difficulty, thereby improving the production efficiency of the wall-mounted indoor unit.
Referring to FIG. 4 to FIG. 6, based on the above embodiments, the manner in which the end cover 30 is mounted to the face frame 10 is not specifically limited herein. For example, the end cover 30 may be detachably connected to the face frame 10 through a connecting structure selected from any one or various combination of a snap structure, a screw-slot structure, and a slot-rail structure. Since the end cover 30 is integrated with the face frame 10, the end cover 30 may be detachably connected to the face frame 10 through the end plate 20.
Specially, the face frame 10 has a flange 13 extending along a circumference of the end plate 20. The flange 13 is enclosed to form a receiving area, the end cover 30 is disposed in the receiving area, and the end cover 30 is fixedly connected to the face frame 10 through the snap structure.
Referring to FIG. 4 to FIG. 6 again, in the present embodiment, in order to facilitate the installation of the end cover 30, the end cover 30 includes a cover plate 31 and a frame 32 matching a periphery of the cover plate 31, and the cover plate 31 is detachably connected to the face frame 10 through the frame 32. Specially, the frame 32 is matching the periphery of the cover plate 31 to protect the entire periphery of the cover plate 31 from damage. During the assembly process, the frame 32 may be first installed in the receiving area of the end of the face frame 10, and then the end cover 30 may be pressed into the frame 32. The assembly process is relatively simple and less difficult.
It is obvious that the frame 32 may be detachably connected to the face frame 10 through at least one connecting structure selected from a snap structure, a screw-slot structure, or a slot-rail structure. Optionally, the frame is connected to the face frame 10 through the snap structure. Specially, the frame 32 includes a plurality of buckles 321 spaced along a periphery of the frame 32, and a side of the end plate 20 defines a plurality of buckle positions 21 corresponding to the plurality of the buckles 321 respectively, and each of the buckles 321 is snap fit to each corresponding the buckle position 21. The snap structure may be disassembled and assembled by simply pulling or pressing, and the operation process is relatively simple and easy to operate.
It is obvious that, in other embodiments, the frame 32 may be connected to the face frame 10 through the screw-slot structure. For example, the face frame 10 includes a plurality of screw posts protruding from the frame 32. The frame 32 includes a plurality of through holes corresponding to the plurality of the screw posts along the circumference thereof. Each of the through hole is connected to each corresponding screw post through a screw.
Referring to FIG. 4, FIG. 5 and FIG. 7, according to any of the above embodiments, a lower surface of the housing includes a windshield strip 40 extending along a length direction of the wall-mounted indoor unit. Due to the presence of the windshield strip 40, the lower surface of the housing is not a smooth surface at a location near the air outlet. Thus, when the air outlet blows air into the indoor environment, the air under the bottom of the housing is blocked by the windshield strip 40, and it is difficult to move along the lower surface of the housing, that is to say, it is difficult to return along the bottom surface of the housing along the bottom edge of the air outlet to the wall-mounted indoor unit (as shown in FIG. 3), thereby reducing the return air flow, the suction noise, effectively reducing the noise at the position of the air outlet, and improving the user experience.
In order to improve the integrity of the wall-mounted indoor unit, the length of the windshield strip 40 is substantially the same as the length of the wall-mounted indoor unit. The windshield strip 40 is extended below the end cover 30, and the end of the windshield strip 40 is connected with the bottom of the end cover 30. In this way, the end cover 30 may be supported by the windshield strip 40, which can enhance the stability. Moreover, the windshield strip 40 is connected to the end cover 30 and the face frame 10, which can greatly improve the firmness of the assembly.
Referring to FIG. 4, FIG. 5 and FIG. 7 again, further, in order to facilitate the connection of the end cover 30 to the face frame 10, the bottom of the end cover 30 defines a limiting groove 322, and the end of the windshield strip 40 is inserted into the limiting groove 322. Specially, the bottom of the frame 32 of the end cover 30 defines the limiting groove 322, the end of the windshield strip 40 is extended below the end cover 30 and is inserted into the limiting groove 322, such that the windshield strip 40 is integrated with the frame 32 to improve structural integrity.
Referring to FIG. 4, FIG. 7 to FIG. 9, according to the above embodiments, it is considered that when the end cover 30 is detached, the end of the windshield strip 40 protrudes from the end face of the face frame 10, and is easily broken during transportation or assembly. Moreover, the windshield strip 40 may affect the smooth placement of the wall-mounted indoor unit. Therefore, in the present embodiment, the windshield strip 40 may detachably connected to the face frame 10. When placed or transported, the windshield strip 40 may be detached so that the lower surface of the face frame 10 is relatively flat for easy placement or packaging. After the wall-mounted indoor unit is installed, the windshield strip 40 is mounted to the lower surface of the face frame 10.
Referring to FIG. 7 to FIG. 9, as for the detachable connection manner of the windshield strip 40 and the face frame 10, the windshield strip 40 may be connected to the face frame 10 through at least one connecting structure selected from a snap structure, a screw-slot structure, a magnetic connecting structure, or a slot-rail structure.
In an embodiment, the windshield strip 40 may be fixedly connected to the face frame 10 through the snap structure. Specially, an upper side surface of the windshield strip 40 is provided with a plurality of mounting buckles protruded backwards; and a lower surface of the face frame 10 includes a plurality of mounting holes 11 facing the mounting buckles, and each of the mounting buckle is inserted into each corresponding mounting hole 11.
Since the windshield strip 40 is located on the lower surface of the face frame 10, the windshield strip 40 may be loosened. Based on this, in order to avoid this, a lower edge of the mounting hole 11 is provided with a support rib 12 extended forwards, and the support rib 12 is abutted against a rear side of the windshield strip 40. The support rib 12 supports the windshield strip 40 such that the mounting buckle of the windshield strip 40 is tightly fastened in the mounting hole 11 so that the windshield strip 40 is not easily loosened.
In another embodiment, the windshield strip 40 is inserted and fixed with the face frame 10. Specifically, a mounting groove is disposed on a lower surface of the housing, and a card hole is disposed around the mounting groove; the outer periphery of the windshield strip 40 is provided with an elastic buckle 321, and the windshield strip 40 is inserted into the corresponding mounting groove, and the elastic buckle 321 is snap fit to the corresponding card hole.
In still another embodiment, the windshield strip 40 is fixedly connected to the face frame 10 through the magnetic connecting structure. Specifically, a first magnetic member is disposed on a lower surface of the housing, and an upper surface of the windshield strip 40 is provided with a second magnetic member that cooperates with the first magnetic member. The second magnetic member is magnetically connected to the first magnetic member.
In yet another embodiment, the windshield strip 40 is fixedly connected to the face frame 10 through the slot-rail structure. Specifically, a sliding groove extending along the length direction of the air outlet is defined in the lower surface of the housing, and the windshield strip 40 is provided with a sliding rail, and the sliding rail is inserted and matched with the corresponding sliding groove. The windshield strip 40 may be disassembled by pulling the windshield strip 40 laterally.
Nowadays, the commercially available wall-mounted indoor unit is installed on the wall of the room, and is blown to the indoor environment through the air outlet to cool or heat the indoor environment. When the conventional wall-mounted indoor unit is in operation, there is a problem that the noise at the position of the air outlet is relatively loud. It is generally believed that the noise at the position of the air outlet is caused by a change in the wind speed at the air outlet or a collision between the air outlet and the air guiding plate.
However, after repeated tests, it is found that when the air outlet blows air to the indoor environment, the position of the air outlet is in a negative pressure state, and the bottom of the wall-mounted indoor unit is in a positive pressure state. Therefore, the air below the bottom of the wall-mounted indoor unit will flow back along the bottom surface along the lower edge of the air outlet into the wall-mounted indoor unit, which will generate a large suction noise, thereby leading to an increase in noise at the position of the air outlet. Thus, the present disclosure provides a wall-mounted indoor unit capable of reducing the suction noise of the wall-mounted indoor unit, improving the user experience.
Referring to FIG. 10 to FIG. 12, in another embodiment, the housing 100 of the wall-mounted indoor unit includes an air outlet 101, and the air outlet 101 is extended along a length direction of the housing 100. The wall-mounted indoor unit further includes a windshield strip 200. The windshield strip 200 is disposed on a lower surface of the housing 100, and the windshield strip 200 is extended along a length direction of the air outlet 101.
Specially, the housing 100 includes a chassis 110, and a face frame 10 and a front panel 130 both mounted on the chassis 110. The wall-mounted indoor unit further includes a heat exchanger and a cross-flow wind turbine 400. The heat exchanger and the cross-flow wind turbine 100 are both mounted on the chassis 110. The top of the housing 100 includes an air inlet, and the front lower portion or the bottom of the housing 100 includes an air outlet 101. When the wall-mounted indoor unit is in operation, the cross-flow wind turbine 400 drives the air from the air inlet into the interior of the housing 100. This part of the air passes through the heat exchanger inside the housing 100 to form blast air, and finally the blast air is blown from the air outlet 101 to the indoor environment. It should be noted here that the bottom surface of the housing 100 refers to a surface substantially parallel to the horizontal plane. For the lower surface, when there is no chamfer between the bottom surface and the front surface of the housing 100, the lower surface refers to the bottom surface; when there is a chamfer between the bottom surface and the front surface of the housing 100, the lower surface refers to the bottom surface and the chamfered surface.
The air outlet 101 may be defined in a front lower portion of the housing 100, or may be defined in a bottom of the housing 100, and the windshield strip 200 is located at a rear side of the air outlet 101. The windshield strip 200 protrudes downwards from the lower surface of the housing 100 such that the position of the lower surface of the housing 100 near the air outlet 101 is not a smooth surface.
In the technical solutions of the present disclosure, the windshield strip 200 is disposed on the lower surface of the housing 100, and the windshield strip 200 is near the air outlet 101. Due to the presence of the windshield strip 200, the lower surface of the housing 100 is not a smooth surface at a location near the air outlet 101. Thus, when the air outlet 101 blows air into the indoor environment, the air under the bottom of the housing 100 is blocked by the windshield strip 200, and it is difficult to move along the lower surface of the housing 100, that is to say, it is difficult to return along the bottom surface of the housing along the bottom edge of the air outlet 101 to the wall-mounted indoor unit (as shown in FIG. 12), thereby reducing the return air flow, the suction noise, effectively reducing the noise at the position of the air outlet 101, and improving the user experience. In addition, since the return air flow is reduced, the condensation inside the wall unit indoor unit can also be reduced.
In general, there are three types for the position of the air outlet 101. The first type is that the air outlet 101 is defined in the front side of the housing 100; the second type is that at least a part of the air outlet 101 is defined in the intersection of the front side of the housing 100 and the bottom surface of the housing; and the third type is that the air outlet 101 is defined in the bottom surface of the housing 100. (The second type and the third type described above are collectively referred to as at least a part of the air outlet 101 defined in the lower surface of the housing 100).
For the embodiment in which the air outlet 101 is defined in the front side of the housing 100, the windshield strip 200 is located below the air outlet 100. At this time, the vertical distance H between the windshield strip 200 and the lower edge of the air outlet 101 is no more than one tenth of the height of the wall-mounted indoor unit (referring to FIG. 12). Of course, H may be 0 (that is, the lower edge of the air outlet is flush with the bottom surface).
There are two cases in which at least a part of the air outlet 101 is defined in the lower surface of the housing 100:
In the case where at least a part of the air outlet 101 is defined in the intersection of the front side of the housing 100 and the bottom surface of the housing 100 based on the chamfer between the bottom surface and the front surface of the housing 100, the windshield strip 200 may be disposed on the bottom surface or at the chamfer.
In the case where the air outlet 101 is defined in the lower surface, the air outlet may be defined in the chamfer, or the air outlet may be defined in the bottom surface. Since the windshield strip 200 is located at the rear side of the air outlet, at this time, both the windshield strip and the air outlet are defined in the bottom surface.
Subsequent embodiments will be explained mainly by taking the air outlet at the above chamfer as an example.
Referring to FIG. 11 and FIG. 12, in the present embodiment, the air outlet 101 is defined in a front lower portion of the housing 100, and the windshield strip 200 is located below the air outlet 101. The rear side of the windshield strip 200 is smoothly connected to the lower surface of the housing 100 to reduce noise generated by air cushioning. The windshield strip 200 may be disposed at a middle or a front of a lower surface of the housing 100. However, in order to enhance the wind shielding effect of the windshield strip 200, it is preferable that the windshield strip 200 may be disposed at the front of the lower surface of the housing 100.
Referring to FIG. 11 and FIG. 12 again, in order to ensure that the windshield strip 200 has a better wind shielding effect, the windshield strip 200 may be disposed near the air outlet 101. As for the distance that the windshield strip 200 may be near the air outlet 101, it is not specifically limited. Optionally, the distance between the windshield strip 200 and the back surface of the housing 100 (shown as L₁ in FIG. 11) is no less than one half of the distance between the lower edge of the air outlet 101 and the back surface of the housing 100 (shown as L₂ in FIG. 11). This ensures that the windshield strip 200 is located on the front side of the lower surface of the housing 100, and is closer to the air outlet 101, thereby effectively preventing the blast air from flowing back from the lower edge of the air outlet 101 into the wall-mounted indoor unit.
Referring to FIG. 11 and FIG. 12, according to the above embodiments, in order to enhance the wind shielding effect of the windshield strip 200, the distance between the windshield strip 200 and the back surface of the housing 100 is no less than three-fifths of the distance between the lower edge of the air outlet 101 and the back surface of the housing 100, for example no less than four-fifths, five-sixths, six-sevens, nine-tenths, and so on.
Referring to FIG. 11 and FIG. 12, in the present embodiment, the wall-mounted indoor unit further includes an air guiding plate 300. The air guiding plate 300 is rotatably mounted to the housing 100 to open or close the air outlet 101. Specially, the air guiding plate 300 is rotatably mounted to the chassis 110. The air guiding plate 300 is rotated downwards to open the air outlet 101, and is rotated upwards to close the air outlet 101. The air guiding plate 300 includes a first side 310 near the windshield strip 200. The air outlet 101 is almost completely opened after the air guiding plate 300 is rotated downwards until the first side 310 is near the lower surface of the housing 100. At this time, the windshield strip 200 may be located on the front side or the rear side of the first side 310.
Referring to FIG. 11 and FIG. 12, in the present embodiment, the windshield strip 200 is located in front of the first side 310 of the air guiding plate 300 after the air guiding plate 300 is rotated downwards until the first side 310 is near the lower surface of the housing 100. At this time, the windshield strip 200 may block the gap 500 between the lower surface of the housing 100 and the air guiding plate 300, thereby reducing the return of the blast air from the gap 500 to the inside of the wall-mounted indoor unit.
Further, a lower end edge of the windshield strip 200 is lower than the first side 310 after the air guiding plate 300 is rotated downwards until the first side 310 is near the lower surface of the housing 100. Therefore, the windshield strip 200 and the first side 310 of the air guiding plate 300 are arranged in a staggered manner at the up and down direction, thereby ensuring that the windshield strip 200 may completely block the gap 500 and greatly reduce the return air flow backflow.
Even if a small amount of effluent air enters from the gap 500, a small portion of the effluent air is blocked by the windshield strip 200 and flows down the windshield strip 200 and away from the lower surface of the housing 100. Then, the effluent air flows along the inner surface of the air guiding plate 300, and is guided to the indoor environment by the air guiding plate 300, and does not flow back into the interior of the wall-mounted indoor unit. That is to say, the windshield strip 200 may block the return air from the outside of the gap 500, and may also guide the air leaking from the gap 500 into the inner surface of the air guiding plate 300 to be led out by the air guiding plate 300.
Referring to FIG. 13, according to the above embodiments, since the windshield strip 200 protrudes downward from the lower surface of the housing 100, an angle facing rear direction is formed between a downwards extending direction of the windshield strip 200 and the lower surface of the housing 100. In order to enhance the wind shielding effect and the wind guiding effect of the windshield strip 200, the angle is optionally no more than 90°. If the angle is 90°, it is equivalent that the windshield strip 200 is substantially inverted L-shaped with the lower surface of the housing 100. If the angle is no more than 90°, the windshield strip 200 is substantially 7 -shaped with the lower surface of the housing 100.
Referring to FIG. 14, in an embodiment, the angle is no more than 90°, that is to say, the windshield strip 200 is substantially 7 -shaped with the lower surface of the housing 100, and the lower edge of the windshield strip 200 is deflected towards the air guiding plate 300. It should be noted here that the rear side of the windshield strip 200 may be a flat or curved surface. Thus, the windshield strip 200 blocks most of the return air from the outside of the gap 500. Even if a small portion of the return air leaks from the gap 500, the windshield strip 200 guides the portion of the return air to the air guiding plate 300 so that it is led out along the air guiding plate 300.
In theory, the smaller the angle, the better. Conversely, when the angle is small, the windshield area of the windshield strip 200 is also small. Therefore, in order to ensure that the windshield strip 200 can maintain a better wind shielding effect, the angle is at least 30° and is no more than 60°. For example, the angle may be 30°, 35°, 40°, 45°, 50°, 55°, and the like.
Referring to FIG. 10 and FIG. 11, according to any of the above embodiments, the windshield strip 200 can be detachably connected to the housing 100 in view of the fact that the windshield strip 200 may affect the placement of the wall-mounted indoor unit. When placed or transported, the windshield strip 200 can be detached so that the lower surface of the housing 100 is relatively flat for easy placement or packaging. After the wall-mounted indoor unit is installed, the windshield strip 200 is mounted to the lower surface of the housing 100.
Referring to FIG. 10 and FIG. 11, as for the detachable connection manner between the windshield strip 200 and the housing 100, the windshield strip 200 may be connected to the housing 100 through at least one connecting structure selected from a snap structure, a screw-slot structure, a magnetic connecting structure, or a slot-rail structure.
In an embodiment, a mounting groove is disposed on a lower surface of the housing 100, and a card hole is disposed around the mounting groove; the outer periphery of the windshield strip 200 is provided with an elastic buckle, and the windshield strip 200 is inserted into the corresponding mounting groove, and the elastic buckle is engaged with the corresponding card hole.
In another embodiment, a first magnetic member is disposed on a lower surface of the housing 100, and an upper surface of the windshield strip 200 is provided with a second magnetic member that cooperates with the first magnetic member. The second magnetic member is magnetically connected to the first magnetic member.
In yet another embodiment, a sliding groove extending along the length direction of the air outlet 101 is disposed on the lower surface of the housing 100, and the windshield strip 200 is provided with a sliding rail, and the sliding rail is inserted and matched with the corresponding sliding groove. The windshield strip 200 may be disassembled by pulling the windshield strip 200 laterally.
Referring to FIG. 10 and FIG. 11, according to any of the above embodiments, the display of the wall-mounted indoor unit is usually mounted on the front panel 130 and is set to display parameters such as the operating state. However, due to the high position of the front panel 130, the user needs to look up at a large angle to see the display screen, which is likely to cause fatigue of the user's neck. Here, the windshield strip 200 is closer to the user than the front panel 130 in view of the lower position of the windshield strip 200. Therefore, the windshield strip 200 is provided with a display screen which is exposed from the front side of the windshield strip 200. As such, this allows the user to view the display with a small angle or even without looking up.
Referring to FIG. 10 and FIG. 11, in the present embodiment, the surface of the windshield strip 200 is coated with a decorative material layer such that the windshield strip 200 may act as a decorative strip for decorative effects. As for the material of the decorative material layer, it can be selected according to the market demand and the overall color adaptability of the wall-mounted indoor unit, and will not be introduced here. In addition, it is also possible to mount a light strip on the windshield strip 200, with the light strip, the windshield strip 200 can be decorated or used as a night light.
