The same reference numbers in the figures designate the same or similar parts or parts. It will be understood by those skilled in the art that the drawings are not necessarily to scale.

Detailed ways

FIG. 1 is a schematic structural diagram of an air deflector according to an embodiment of the present invention; FIG. 2 is a schematic view from the bottom of the air deflector shown in FIG. 1 ; A schematic cross-sectional view when blowing upwards; FIG. 4 is a schematic cross-sectional view of a wall-mounted air conditioner indoor unit when blowing downwards according to an embodiment of the present invention. The wind direction is indicated by arrows in the figure.

As shown in FIGS. 1 to 4 , the wind deflector 50 according to the embodiment of the present invention may generally include a wind deflector body 51 and at least one outer deflector 53 . The air deflector body 51 is rotatably installed at the air outlet 12 of the housing 10 of the wall-mounted air conditioner indoor unit (rotates around the x-axis, and the x-axis is marked in the figure), and is used to open and close the air outlet 12 and adjust the air outlet 12. The air outlet angle of the air outlet 12, and the direction of the airflow that guides the air outlet 12. For example, as shown in FIG. 3 , the overall air deflector body 51 can be a long arc-shaped plate with a convex surface facing the outside of the air outlet 12 , and its rotational axis x axis is parallel to the length direction of the air deflector body 51 .

When the air deflector body 51 is in the state of closing the air outlet 12 , the side surface facing the inside of the housing 10 is defined as the inner surface 511 , and the side surface facing the outside of the housing 10 is the outer surface 512 . Each outer deflector 53 is installed on the air deflector body 51 with an interval from the outer surface 512 of the air deflector body 51 to guide the airflow direction at the air outlet 12 together with the air deflector body 51 . The air flow channel formed between the outer deflector 53 and the air deflector body 51 is used to allow air flow therethrough.

In the heating mode of the wall-mounted air conditioner indoor unit of the present invention, the outer deflector 53 can guide the hot air to blow downward at a larger downward blowing angle (the angle between the downward air outlet direction and the vertical direction), which is very beneficial to heating process. In addition, the air guiding range of the air guiding plate 50 can be expanded, so that the wall-mounted air conditioner indoor unit can take into account both the air outlet angle and the air volume. Specifically, in order to improve the air supply comfort, when the indoor unit of the wall-mounted air conditioner is heated, it is generally desirable that the air deflector guide the hot air to blow out at an angle as vertically downward as possible. However, when the air deflector of the traditional wall-mounted air conditioner indoor unit is rotated to a downward blowing angle close to the limit, the angle between the air deflector and the plane where the air outlet is located is too small, so that the opening degree is very small (the opening degree of the air deflector It refers to the degree to which the air outlet is opened. When the air deflector completely closes the air outlet, the opening degree is zero. When the surface of the air deflector is close to the surface of the air outlet, the opening degree is 100%, and the air outlet is the smoothest), so that the The air deflector seriously blocks the air outlet, and the air volume becomes very small. This limits the wind guide angle range of the wind deflector. Especially in the vertical wind guide, it is difficult to take into account the wind guide angle and air volume.

In the embodiment of the present invention, the outer deflector 53 can blow the wind downward. Therefore, when the indoor unit of the wall-mounted air conditioner is heated, it is not necessary to rotate the air deflector body 51 to a state that is too close to the vertical downward state (that is, close to the state where the air outlet is closed), so as to ensure that the air deflector 50 is sufficiently large as a whole. The opening degree, the air volume is not affected. It can be seen that the embodiment of the present invention takes into account both the air supply angle and the air volume.

In addition, during the air guiding process of the air deflector 50, part of the airflow is discharged from the narrow airflow channel between the outer deflector 53 and the air deflector body 51, so that the wind speed is higher and the air supply distance is longer.

As shown in FIG. 2 and FIG. 4 , the end of the air deflector body 51 facing the inside of the casing 10 when guiding the wind is defined as the windward end (the B end marked in the figure), and the end facing the outside of the air outlet 12 is the air outlet end ( A terminal marked in the figure). In the direction from the windward end to the air outlet end (that is, the general airflow direction), the distance between the outer deflector 53 and the air deflector body 51 is gradually increased. In other words, the airflow channel formed between the outer deflector 53 and the air deflector body 51 is made to have a gradually expanding shape. When blowing under the heating of the air conditioner, the outer deflector 53 of this shape can guide the wind downward at a more vertical angle. Specifically, the axis of each outer deflector 53 can be parallel to the rotation axis (x-axis) of the air deflector body 51, and the convex surface faces the arc-shaped plate of the air deflector body 51, so as to realize the gradual increase of the above-mentioned separation distance. big request.

The outer deflector 53 can be arranged close to the windward end (end B) to maximize the downward wind guiding effect of the outer deflector 53 , as shown in FIG. 4 .

As shown in FIG. 2 , the number of at least one outer deflector 53 may be multiple, and the plurality of outer deflectors 53 are arranged at intervals along the direction parallel to the rotation axis (x axis) of the air deflector body 51 . In this way, the outer deflector 53 can act on the air flow basically everywhere in the direction of the air deflector body 51 parallel to its rotation axis, and the air flow can be blocked in the dimension of the air deflector body 51 parallel to the x-axis direction. The multiple outer baffles 53 are split and scattered to make the airflow more gentle. As shown in FIG. 2 , the length direction of the wind deflector body 51 is defined to be parallel to its rotational axis x-axis, so that a plurality of outer deflectors 53 are arranged from one end of the length direction of the wind deflector body 51 to the other end, so that the Covers the entire length of the wind deflector body 51 .

As shown in FIG. 2 , each outer deflector 53 is connected to the air deflector body 51 by a plurality of outer partitions 531 . The plurality of outer partitions 531 are arranged at intervals along the direction of the rotation axis of the air deflector body 51 to separate the air flow passages between the air deflector body 51 and the outer air deflector 53 . On the one hand, the outer baffle 531 serves to connect the outer deflector 53 and the air deflector body 51 , and on the other hand, it can also split the airflow to make the airflow softer.

In some embodiments, as shown in FIGS. 1-3 , the air deflector 50 further includes at least one inner air deflector 52 . Each inner deflector 52 is installed on the air deflector body 51 with an interval from the inner surface of the air deflector body 51 to guide the airflow direction at the air outlet 12 together with the air deflector body 51 .

By arranging the inner air guide plate 52, the air guide range of the air guide plate 50 can be expanded, so that the indoor unit of the wall-mounted air conditioner can take into account both the air outlet angle and the air volume. For example, in order to improve the air supply comfort, when the wall-mounted air conditioner indoor unit is refrigerating, it is usually desirable that the air deflector guides the cold air to blow out vertically upward as much as possible. However, when the air deflector of the traditional wall-mounted air conditioner indoor unit is rotated to the upper blowing angle close to the limit, the angle between the air deflector and the plane where the air outlet is located is too small, that is, the opening degree is very small (the opening degree of the air deflector refers to When the air deflector completely closes the air outlet, the opening degree is zero. When the surface of the air deflector is close to perpendicular to the surface of the air outlet, the opening degree is 100%, and the air outlet is the smoothest.) The plate will seriously block the air outlet, and the air volume becomes very small. This limits the wind guide angle range of the wind deflector. Especially in the vertical wind guide, it is difficult to take into account the wind guide angle and air volume.

However, in the embodiment of the present invention, since the position of the inner deflector 52 is relatively high, it is beneficial to blow the wind upward. Therefore, during the cooling operation of the indoor unit of the wall-mounted air conditioner, it is not necessary to rotate the air deflector body 51 to a state that is too close to vertical (that is, close to the state of closing the air outlet), so as to ensure that the air deflector 50 has a large enough opening. Avoid air volume being affected. It can be seen that the embodiment of the present invention takes into account both the air supply angle and the air volume.

The utility model is provided with the outer deflector 53 and the inner deflector 52 at the same time, which takes into account the requirements of cooling rising air and heating lower air output, and taking into account the air volume and air outlet angle, and the function is very comprehensive.

In the present invention, when the air flow inside the casing 10 is blown toward the air outlet 12 and flows through the surface of the air deflector body 51, it will be disturbed by the outer deflector 53 and the inner deflector 52, and a part of the airflow will flow from the inner deflector. The air flow channel between 52 and the air deflector body 51, and the air flow channel between the outer deflector 53 and the air deflector body 51 flow out, that is, the air flow is split and scattered, becoming softer, and the wind feeling is closer to natural wind, to achieve the effect of comfortable air supply.

As shown in FIGS. 1 to 3 , in the direction from the windward end (B end) to the wind outlet end (A end), the distance between the inner deflector 52 and the air deflector body 51 is gradually increased. In other words, the airflow channel formed between the inner deflector 52 and the air deflector body 51 is in a gradually expanding shape. When blowing upwards for air conditioning and refrigeration, the inner deflector 52 of this shape can be raised to guide the wind at a more vertical angle. Specifically, each inner deflector 52 can be an arc-shaped plate whose axis is parallel to the rotation axis (x-axis) of the air deflector body 51, and the convex surface faces toward the air deflector body 51, so as to realize the gradual increase of the above-mentioned separation distance. big request.

The inner deflector 52 can be arranged near the air outlet end (end A) to maximize the upward wind guiding effect of the inner deflector 52 , as shown in FIG. 3 .

As shown in FIG. 1 , the number of at least one inner deflector 52 may be plural, and the plurality of inner deflectors 52 are arranged at intervals along the direction parallel to the rotation axis (x axis) of the air deflector body 51 . In this way, the air deflector body 51 basically has the inner air deflector 52 acting on the air flow everywhere in the direction parallel to its rotation axis, and the air flow is blocked in the dimension of the air deflector body 51 parallel to the x-axis direction. The plurality of inner baffles 52 are split and broken up. As shown in FIG. 1 , the length direction of the air deflector body 51 is defined to be parallel to the axis of rotation x, so that a plurality of inner air deflectors 52 are arranged from one end of the length direction of the air deflector body 51 to the other end so that the Covers the entire length of the wind deflector body 51 .

As shown in FIG. 2 , each inner baffle 52 is connected with the air baffle body 51 through a plurality of inner partitions 521 . The plurality of inner baffles 521 are arranged at intervals along the direction of the rotation axis of the air deflector body 51 to separate the airflow passages between the air deflector body 51 and the inner air deflector 52 . On the one hand, the inner baffle plate 521 serves to connect the inner baffle plate 52 and the air baffle plate body 51 , and on the other hand, it can also split the airflow to make the airflow more gentle.
