All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that, if directional indications (such as up, down, left, right, front, and rear … …) are included in the embodiments of the present invention, the directional indications are merely used to explain the relative positional relationship, movement conditions, etc. between the components in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are correspondingly changed.
In addition, if there is a description of "first", "second", etc. in the embodiments of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present invention.
The invention provides a wall-mounted indoor unit, which can improve the temperature distribution uniformity of air outlet, reduce the occurrence of head heat and foot coldness and further improve the comfort of the wall-mounted indoor unit. It should be noted that the wall-mounted indoor unit may be a horizontal-mounted indoor unit or a vertical-mounted indoor unit. In the following embodiments, a cross-hanging indoor unit will be explained as an example.
Referring to fig. 1 to 3, in an embodiment of the wall-mounted indoor unit of the present invention, the wall-mounted indoor unit includes a housing 100, a heat exchanger 200, and a cross-flow wind wheel 300. The casing 100 is provided with an air inlet 101 and an air outlet 102 communicated with the air inlet 101. The heat exchanger 200 and the cross flow wind wheel 300 are installed in the shell 100, and the heat exchanger 200 is arranged in a multi-fold mode and surrounds the cross flow wind wheel 300. When the wall-mounted indoor unit works, the cross-flow wind wheel 300 rotationally drives air to enter the shell 100 from the air inlet 101, and the air is blown out from the air outlet 102 after heat exchange of the heat exchanger 200.
Referring to fig. 2 and 3, the wall-mounted indoor unit further includes a first air deflector 600 and a second air deflector 700. The first air deflector 600 is rotatably installed at the housing 100 and located at an upper portion of the air outlet 102. The second air deflector 700 is rotatably installed at the housing 100 and located at a lower portion of the air outlet 102. Wherein, the upper edge of the first air deflector 600 rotates downward to open the upper portion of the air outlet 102, and the upper edge of the second air deflector 700 rotates to open the lower portion of the air outlet 102. It should be noted that, the air outlet 102 extends along the length direction of the wall-mounted indoor unit in a long strip shape, and a plane perpendicular to the width direction of the air outlet 102 divides the air outlet 102 into two parts, namely an upper part of the air outlet 102 and a lower part of the air outlet 102.
Referring to fig. 3, 5-a and 5-B, the wall-mounted indoor unit is in a cooling mode, and the air outlet 102 blows out cool air. At this time, the upper edges of the first and second air deflectors 600 and 700 may be rotated downward, the upper edges of the first and second air deflectors 600 and 700 may be inclined forward and upward, and an air guide path extending forward and upward may be formed between the first and second air deflectors 600 and 700. The cool air flows against the surface walls of the first and second air guide plates 600 and 700 by the "coanda effect" so as to be guided to blow forward and upward from the air guide path to the upper and middle space (e.g., ceiling) in the room. In the process of gradually settling the cold air downwards, the cold air is gradually mixed with the hot air in the indoor lower space, so that the user is gradually cooled from the head to the feet.
Referring to fig. 3, 6-a and 6-B, the wall-mounted indoor unit is in a heating mode, and the air outlet 102 blows out hot air. At this time, the upper edges of the first and second air deflectors 600 and 700 may be rotated downward to a large angle, and the upper edges of the first and second air deflectors 600 and 700 may be inclined downward, forming an air guide path extending forward and downward between the first and second air deflectors 600 and 700. The hot air flows against the surface walls of the first and second air guide plates 600 and 700 by the "coanda effect" and is thus guided to blow from the air guide path toward the front lower side to the indoor middle-lower space (e.g., floor). In the process that the hot air gradually floats upwards, the hot air is gradually mixed with cold air in an indoor upper space, so that the user is gradually warmed from the feet to the head.
Referring to fig. 3, when the wall-mounted indoor unit is not in operation, the upper edges of the first air deflector 600 and the second air deflector 700 may be rotated upwards to a maximum angle, so that the first air deflector 600 closes the upper portion of the air outlet 102, and the second air deflector 700 closes the lower portion of the air outlet 102, thereby realizing complete closing of the air outlet 102 and preventing external dust from falling into the housing 100 from the air outlet 102.
According to the technical scheme, the first air deflector 600 is arranged at the upper part of the air outlet 102, the second air deflector 700 is arranged at the lower part of the air outlet 102, the upper part of the air outlet 102 can be opened and closed by the first air deflector 600, and the lower part of the air outlet 102 can be opened and closed by the second air deflector 700. In the cooling mode, the first and second air deflectors 600 and 700 are rotated to be inclined upward, so that cool air can be blown out to the upper and middle spaces in the room. In the heating mode, the first and second air deflectors 600 and 700 are rotated to incline downward, so that hot air can be blown out toward the indoor middle-lower space (see the above description for detail). Therefore, the wall-mounted indoor unit can improve the uniformity of the temperature of the air outlet by adjusting the rotation angles of the first air deflector 600 and the second air deflector 700, reduce the occurrence of the condition that the head is hot and the feet are cold, and further improve the comfort of the wall-mounted indoor unit.
Referring to fig. 3 and fig. 4, in an embodiment, a housing 100 includes a volute 400 and a volute tongue 500 that cooperates with the volute 400 to form an air outlet duct 103, where the air outlet duct 103 communicates an air inlet 101 with an air outlet 102; the first air deflector 600 is rotatably mounted on the volute tongue 500, and the second air deflector 700 is rotatably mounted on the volute 400.
Specifically, the middle lower edge of the first air deflector 600 is pivotally connected to the volute tongue 500, so that the upper edge of the first air deflector 600 can open the upper portion of the air outlet 102 when it rotates downward. The lower edge of the second air guide plate 700 is pivoted to the scroll 400 such that the lower portion of the air outlet 102 can be opened when the upper edge of the second air guide plate 700 is rotated downward.
In one embodiment, the first air deflector 600 has a closed state (as shown in fig. 3 or fig. 6-a, 6-B) rotated to a position where the upper edge thereof is close to the front end of the volute tongue 500; and, the first air deflection 600 has a first open state (fig. 5-a) rotated to divide the air outlet 102 into two parts, an upper air outlet and a lower air outlet, and/or the first air deflection 600 has a second open state (fig. 5-B) rotated to a lower edge thereof near the rear end of the volute tongue 500. Thus, the wall-mounted indoor unit has at least two cooling modes (a first cooling mode and a second cooling mode) and at least one heating mode. Wherein:
Referring to fig. 5-a, the wall-mounted indoor unit is in the first cooling mode, and the first air deflector 600 is opened to the first open state. At this time, an air guide path is formed between the first air guide plate 600 and the volute tongue 500, and another air guide path is formed between the first air guide plate 600 and the second air guide plate 700. The cool air blown out from the air outlet 102 is divided into two layers by the first air guide plate 600, wherein one layer of cool air is blown out from the air guide path between the first air guide plate 600 and the volute tongue 500 to the front upper side. The other layer of cool air is blown out from the air guide path between the first air guide plate 600 and the second air guide plate 700 to the front upper side. The wind speed of the dispersed two layers of cold air is reduced, and the two layers of cold air can respectively reach the middle-upper space in the room, so that the simultaneous occurrence of the ceiling air flow and the common refrigeration air flow is realized.
Referring to fig. 5-B, the wall-mounted indoor unit is in the second cooling mode, and the first air deflector 600 is opened to the second open state. At this time, the air outlet 102 forms only a single air guide path between the first air guide plate 600 and the second air guide plate 700. The cool air blown out from the air outlet 102 is intensively blown out from the single air guiding path forward and upward, the cool air has a large wind speed and a long air guiding path, and thus, the cool air can reach the indoor upper space, so that a single ceiling refrigerating air flow appears on the ceiling.
The first refrigeration mode and the second refrigeration mode can generate comfortable airflow. It should be noted that, the angle through which the upper edge of the first air deflector 600 turns downward in the second cooling mode is larger than the angle through which the upper edge of the first air deflector 600 turns downward in the first cooling mode.
Referring to fig. 6-a, the wall-mounted indoor unit is in the first heating mode, the first air deflector 600 rotates to the covering state, and the second air deflector 700 opens the lower portion of the air outlet 102. The hot air blown out from the air outlet 102 can only flow to the lower part of the air outlet 102 under the blocking action of the first air deflector 600, and the hot air is guided by the second air deflector 700 to blow downwards, so that the hot air flow of the floor is realized.
Referring to fig. 3 and 4, in an embodiment, a volute tongue 500 of a conventional wall-mounted indoor unit extends directly from back to front, and an air outlet 102 formed between a front end of the volute tongue 500 and the volute 400 has a smaller width. If the wall-mounted indoor unit of the present invention adopts the conventional design of the volute tongue 500, it is difficult to install the first air deflector 600. To overcome the above-mentioned difficulty in mounting the first air deflector 600, the volute tongue 500 may optionally include a first volute tongue plate 510 and a second volute tongue plate 520 extending obliquely upward from the front end of the first volute tongue plate 510, where the first air deflector 600 is rotatably mounted to the second volute tongue plate 520.
Specifically, the first volute tongue plate 510 and the volute 400 enclose to form the air outlet duct 103, the second volute tongue plate 520 extends obliquely upward, and the air outlet 102 formed between the second volute tongue plate 520 and the front end of the volute 400 has a larger width, so that the first air deflector 600 is convenient to be mounted on the second volute tongue plate 520. When the first air deflector 600 is opened to the second open state, the lower edge of the first air deflector 600 approaches or abuts against the connection position of the first volute tongue plate 510 and the second volute tongue plate 520 (as shown in fig. 5-B).
Further, considering that when the first air guide plate 600 is opened to the second opened state (second cooling mode), cold air may flow upward along the surface of the front panel 130 with wall attached, so that the temperature difference of air at the inner side of the front panel 130 is large, and condensed water is easily formed on the inner surface of the front panel 130.
To avoid this, the volute tongue 500 may optionally further include a wind deflector 530 extending forward from the upper end of the second volute tongue 520, the front edge of the wind deflector 530 extending forward to the lower edge of the front panel 130 of the casing 100. In the first cooling mode, the cool air blown out from between the first air guide plate 600 and the volute tongue 500 is separated from the front panel 130 at the air deflector 530 and blown out forward and upward, so that the cool air does not flow along the surface wall of the front panel 130, and the generation of condensed water is reduced.
With continued reference to fig. 3 and fig. 4, in an embodiment, considering that the width of the air outlet 102 is smaller, if the first air guiding plate 600 is to be additionally arranged on the air outlet 102, the width of the first air guiding plate 600 is difficult to be designed larger, so that the air guiding path formed by the first air guiding plate 600 and the second air guiding plate 700 is shorter, and the air outlet is not easy to be sent to a far position. Therefore, an improvement in the structure of the first air deflection 600 is necessary.
Here, alternatively, the first air guide plate 600 includes an outer guide plate 610 and an inner guide plate 620 extending from a lower edge of the outer guide plate 610 toward an inside of the air outlet 102; when the first air guide plate 600 and the second air guide plate 700 rotate upwards, the outer guide plate 610 and the second air guide plate 700 are correspondingly spliced to cover the air outlet 102, and the inner guide plate 620 is positioned on the inner side of the second air guide plate 700.
Specifically, the inner guide plate 620 and the outer guide plate 610 are integrally formed. When the air outlet 102 is closed, the first air guide plate 600 is first rotated to the covering state, and at this time, the outer guide plate 610 of the first air guide plate 600 covers the upper portion of the air outlet 102, and the inner guide plate 620 of the first air guide plate 600 moves to the inner side of the air outlet 102, so as to avoid the subsequent interference of the inner guide plate 620 to the second air guide plate 700. The second air guide plate 700 is then rotated until its upper edge is spliced with the lower edge of the outer guide plate 610, so that the second air guide plate 700 covers the lower portion of the air outlet 102. The first air deflection 600 of the present invention effectively lengthens the air deflection path and greatly lengthens the air supply distance, compared to the conventional air deflection structure having only the outer guide plate 610.
Referring to fig. 4, 5-a and 5-B, in order to enhance the wall-attached flow effect of the outlet air, the cross section of the inner guide 620, which is cut by a plane perpendicular to the length direction thereof, is curved away from the second air deflector 700. It should be noted that the cross section is a virtual cross section, and is used to describe the shape and structure of the inner guide 620. By the design, the effect that the air outlet flows along the arc-shaped surface of the inner guide plate 620 can be enhanced, and the coanda effect is better realized; and, the impact of the fast flowing air-out air to the inner guide plate 620 can be lightened, and the air-out noise is reduced.
In addition, the second air guide plate 700 may be curved in such a manner that a cross section taken by a plane perpendicular to the longitudinal direction thereof is curved away from the inner guide plate 620. It should be noted that this cross section is a virtual cross section, and is used to describe the shape and structure of the second air deflector 700. By the design, the inner guide plate 620 and the second air guide plate 700 are matched to form a bracket, so that the air outlet air can be guided to pass through the space between the first air guide plate 600 and the second air guide plate 700, the effect that the air outlet air flows along the arc-shaped surface of the inner guide plate 620 can be enhanced, and the air supply distance can be prolonged.
In an embodiment, for the driving modes of the first air deflector 600 and the second air deflector 700, the two may be driven synchronously by a linkage mechanism, or may be driven separately by different driving structures. In order to facilitate the first air guide plate 600 and the second air guide plate 700 to rotate through different angles to obtain multiple air outlet modes, optionally, the wall-mounted indoor unit further comprises a first motor (not shown) and a second motor (not shown), wherein the first motor is connected with the first air guide plate 600, and the second motor is connected with the second air guide plate 700. The first and second air deflectors 600 and 700 may be individually controlled to rotate by the first and second motors, respectively.
Referring to fig. 7-a and 7-B, in one embodiment, considering that the air velocity of the air immediately blown out from the air outlet 102 is high, the temperature is low, and the air is directly blown to the user, discomfort (such as cold or dizziness) is easily caused to the user. To avoid this, the plate surface of the first air deflector 600 is optionally provided with a plurality of air outlet holes; and/or, a plurality of air outlet through holes are formed on the plate surface of the second air deflector 700. After passing through the air outlet through holes, the air outlet air is dispersed into a small fine air flow, the wind speed of the fine air flow is reduced, and the fine air flow cannot blow to a user in a straying mode, so that the comfort level of the user is improved, and the windless mode is realized.
Specifically, the air outlet holes are formed in both the first air guide plate 600 and the second air guide plate 700. The air outlet through holes on the first air deflector 600 and the second air deflector 700 are uniformly distributed. When the wall-mounted indoor unit needs a no-wind-sensation mode, the first air deflector 600 and the second air deflector 700 are rotated to cover the air outlet 102, so that the air-out air is emitted outwards from the plurality of air-out through holes, and no wind sensation is realized.
Referring to fig. 5-a and fig. 5-B, according to any of the foregoing embodiments, the wall-mounted indoor unit further includes a third air deflector 800 rotatably installed at an inner side of the air outlet duct 103, and the third air deflector 800 extends along a length direction of the wall-mounted indoor unit. The third air deflection 800 may direct the outlet air to the outlet 102 for the first air deflection 600 and the second air deflection 700. In particular, when the third air guide plate 800 rotates to the point that the front edge thereof is spliced with the lower edge of the first air guide plate 600, the air guide path of the first air guide plate 600 is extended, and thus the air supply distance is greatly prolonged.
Referring to fig. 7-a and 7-B, optionally, a plurality of air outlet holes may be formed in the plate surface of the third air deflector 800. When the third air deflector 800 rotates to the point that the plate surface of the third air deflector crosses the air outlet direction of the air outlet duct 103, the air outlet air blows through the air outlet through holes on the third air deflector 800, so that the windless effect can be further enhanced.
For the driving mode of the third air deflector 800, optionally, the wall-mounted indoor unit further includes a third motor, and the third motor is connected with the third air deflector 800, so as to separately drive the third air deflector 800 to rotate through the third motor.
Referring to fig. 6-a and 6-B, fig. 7-a and 7-B, in order to increase the air outlet surface of the wall-mounted indoor unit according to any of the foregoing embodiments, the casing 100 includes a bottom plate 110, the bottom plate 110 is provided with an air outlet area 111, and the air outlet area 111 is provided with a plurality of air outlet through holes, where the air outlet through holes are communicated with the air inlet 101. Part of the air-out air blown out from the air-out duct 103 can be blown out from the air-out port 102, and the other part of the air-out air is blown out from the air-out through hole of the air-out area 111.
Further, the housing 100 further includes a scroll 400, and the bottom plate 110 is located outside the scroll 400; the scroll case 400 is provided with an air outlet 410, and the air outlet 410 communicates with the air outlet through hole of the air outlet region 111. A part of the outlet air blown out from the outlet duct 103 may be blown out from the air port 410 toward the outlet area 111, and then blown out from the outlet through hole of the outlet area 111.
It is considered that since the air outlet through hole of the air outlet region 111 is opened downward, the air outlet air is blown downward from the air outlet through hole. If the air-out air is hot air, blowing down to the user's feet may warm the user's feet. However, if the air-out air is cool air, the user feels colder by blowing cool air to the foot of the user.
Therefore, it is preferable that the wind deflector 900 is rotatably installed at the wind gap 410, and the wind deflector 900 is rotated to open or close the wind gap 410. In the heating mode, the air vents 410 may be opened by the air flaps 900 so that hot air can be blown down from the air outlet area 111 to the user's feet, warming the user's feet. In the cooling mode, the air passage 410 may be closed by the air deflector 900 so that no cool air is blown out of the air outlet region 111.
In addition, in the no-wind-sensation mode, the wind deflector 900 may be closed, so that the outlet air is blown forward, and the amount of the forward blown air is increased. Of course, the wind guard 900 may be opened, so that the air is blown out by the air outlet 102 and the air outlet area 111 in two parts, effectively increasing the air supply area, and rapidly realizing refrigeration or heating.
The invention also provides an air conditioner which comprises an air conditioner outdoor unit and a wall-mounted indoor unit, wherein the wall-mounted indoor unit is connected with the air conditioner outdoor unit through a refrigerant pipe.
