However, when the cold air or hot air with excessive wind speed blows directly on the human body, it will inevitably cause discomfort to the human body. The long-term exposure of the human body to the cold wind can also cause air-conditioning disease.

Therefore, how to realize the comfortable air supply of the air conditioner has become a technical problem to be solved urgently in the air conditioner industry.

Utility model content

The purpose of the present invention is to provide a wall-mounted air conditioner indoor unit and its wind deflector which overcome the above problems or at least partially solve the above problems.

The purpose of the utility model is to make the wind deflector have the function of upward wind.

A further purpose of the present invention is to make the wind guide angle range of the wind guide plate larger, and to take into account both the wind guide angle and the air volume.

When , guide the supply air flow gradually away from the air deflector body to gradually deflect upward flow; and

A plurality of micro-holes penetrating through two sides of the air-lifting plate are provided, so as to allow part of the heat-exchange air flow to pass through the plurality of micro-holes and then blow into the room.

Optionally, the included angle between the axis of each micro-hole and the surface of the air blowing plate is an acute angle, so that the flow direction of the supply air in the micro-hole and the flow direction on the first side surface are at an acute angle.

Optionally, the projection of the wind board on the first side is located within the range of the wind deflector body.

Optionally, the wind deflector body is a long strip with a length direction parallel to the direction of its rotation axis; and the wind deflector is a long strip extending along the length direction of the wind deflector body, and both ends in the length direction are in the shape of a long strip. Both ends in the longitudinal direction of the wind panel body have a distance.

Optionally, the wind deflector further includes two end plates, and the two end plates are respectively connected between the two ends of the wind deflector along the rotation axis direction of the wind deflector body and the first side surface, so as to close the wind deflector. The space between the two ends and the first side.

Optionally, the wind deflector further includes a plurality of connecting ribs arranged at intervals along the parallel direction of the rotation axis of the wind deflector body, and each connecting rib connects the wind deflector and the wind deflector body.

Optionally, the wind-raising plate is an arc-shaped plate whose central axis is parallel to the rotation axis of the air-guiding plate body, and the convex surface faces toward the air-guiding plate body.

On the other hand, the present utility model also provides a wall-mounted air conditioner indoor unit, comprising: a casing, which is provided with an air outlet; and an air guide plate, which is the air guide plate according to any one of the above, wherein the guide plate is The air plate body is rotatably installed at the air outlet.

Optionally, the wind deflector further includes at least one rotating arm, one end of which is connected to the driving device located inside the housing, and the other end is connected to the wind deflector body, so as to drive the wind deflector body to revolve around the rotating arm under the driving of the driving device.

This makes the upward blowing angle of the supply air flow (the angle between the upward air outlet direction and the vertical direction) smaller, so as to better avoid the human body.

In addition, when the air deflector body guides the wind, part of the air supply air flows through the micro holes on the air raising plate first, and then blows into the room, which makes the air flow more dispersed and soft, achieving a breeze effect, and the wind feeling is closer to nature. wind, to achieve the comfortable air supply of the air conditioner

The utility model realizes the wind raising function only by adding an air raising plate on the main body of the air deflector, the design is very ingenious, the structure is very simple, and the cost is low. Moreover, other structures of the wall-mounted air conditioner indoor unit do not need to be changed, which is very beneficial for mass production and promotion.

Further, the wall-mounted air conditioner indoor unit of the present invention 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 air deflector completely opens the air outlet, the opening degree is 100%, and the air outlet is the smoothest), the air deflector will seriously block Outlet, 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 utility model, the wind raising plate can guide 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 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 has a large enough opening to avoid air volume. affected.

The above and other objects, advantages and features of the present invention will be more apparent to those skilled in the art from the following detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings.

Detailed ways

1 is a schematic structural diagram of an air deflector according to an embodiment of the present invention; FIG. 2 is a schematic view of another perspective view of the air deflector 50 shown in FIG. 1 ; FIG. 3 is a cross-sectional view of the air deflector 50 shown in FIG. 1 ; FIG. 4 It is a schematic diagram of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention. In each figure, the direction of the supply air flow is indicated by a solid arrow, and the direction of the ambient air intake is indicated by a hollow arrow.

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 a wind raising plate 52 . The air deflector body 51 is used to be rotatably installed at the air outlet 12 of the housing 10 of the wall-mounted air conditioner indoor unit (rotate around the x-axis, and the x-axis is marked in the figure). The function of the air deflector 50 is to open and close the air outlet 12 , and can also be used to adjust the air outlet angle of the air outlet 12 . The airflow blown out from the inside of the housing 10 through the air outlet 12 is the air supply airflow. When the air conditioner is cooling, the supply air flow is cold air; when the air conditioner is heating, the supply air flow is hot air.

When the air outlet 12 is opened, the upward side of the air deflector body 51 is the first side, and its surface is the first side 511 ; the downward side is the second side, and its surface is the second side 512 . The end of the air deflector body 51 close to the upstream of the air supply airflow is defined as the windward end (B end), and the end close to the downstream of the air supply air flow is the air outlet end (A end). The flow direction of the supply air flow on the first side surface 511 of the air deflector body 51 is toward the air outlet end.

The wind deflector 52 extends from the first side surface 511 of the wind deflector body 51 , which faces upward when the air outlet 12 is opened, and extends toward the downstream direction of the air flow and gradually away from the wind deflector body 51 , referring to FIG. 3 . That is, in the direction from the upstream to the downstream of the blowing air flow, the distance between the air blowing plate 52 and the first side surface 511 is gradually increased, and the air raising plate 52 is gradually separated from the air deflector body 51 . In this way, when the air supply air flows through the first side surface 511 , the air blowing plate 52 can guide the air supply air current to gradually move away from the air deflector body 51 so as to gradually deflect upward flow. This can make the upward blowing angle of the air supply airflow (the angle between the upward air outlet direction and the vertical direction) smaller, so that the indoor unit of the wall-mounted air conditioner can be better raised and blown, so that the wind can better avoid the human body.

In addition, the air guide plate of the embodiment of the present invention can make the indoor function of the wall-mounted air conditioner 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 air deflector completely opens the air outlet (refer to Figure 5), the opening degree is 100%, and the air outlet is the smoothest.) The air plate will seriously block the air outlet, and the air volume will become 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 wind raising plate 52 can guide 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. In this way, the wall-mounted air conditioner indoor unit takes into account both the air supply angle and the air volume.

The utility model realizes the wind raising function only by adding an air raising plate 52 on the air deflector 50, the design is very ingenious, the structure is very simple, and the cost is low. Moreover, other structures of the wall-mounted air conditioner indoor unit do not need to be changed, which is very beneficial for mass production and promotion.

The blower plate 52 is provided with a plurality of micro-holes 525 penetrating two sides thereof, so as to allow part of the heat exchange air flow to pass through the plurality of micro-holes 525 and then blow into the room, see FIGS. 3 and 4 . After this part of the airflow passes through the micro-holes 525, it will become more dispersed and soft, achieving a breeze blowing effect, and the human body's wind feeling is closer to the natural wind, which is very comfortable.

The inventor realizes that the total ventilation area of the plurality of micro-holes 525 is too large, which will affect the wind-raising effect of the wind-raising plate 52 , so the aperture of the micro-holes 525 and the opening ratio of the wind-raising plate 52 are specially set. For example, the diameter of the micropores 525 can be set between 0.5-2 mm. The porosity of the wind plate 52 (ie the ratio of the opening area to the surface area of one side of the wind plate) is between 25% and 35%. The plurality of micro-holes 525 are densely arranged on the surface of the wind-raising plate 52, for example, evenly distributed in a matrix.

As shown in FIG. 3 , the included angle θ between the axis of each micro-hole 525 and the surface of the air-lifting plate 52 can be made an acute angle, so that the flow direction of the supply air in the micro-hole 525 is in the same direction as the flow direction on the first side surface 511 The acute angle is beneficial for the air supply air on the surface of the first side surface 511 to flow into the micro-holes 525 more smoothly during the flow process.

The projection of the wind board 52 on the first side surface 511 can be located within the range of the wind deflector body 51 . In other words, the distal end (E end) of the blower plate 52 is retracted by a distance in the upstream direction of the blowing air flow compared to the air outlet end (A end) of the air deflector body 51 . It can also be understood in this way that when a vertical line is drawn at the end of the wind panel 52 to the first side surface 511 of the wind panel body 51 , the hanging foot will fall on the first side surface 511 itself rather than the extension surface of the first side surface 511 . In this way, when the air deflector body 51 closes the air outlet 12 , the air blowing plate 52 can be prevented from contacting with the upper edge of the air outlet 12 .

The central axis of the wind deflector 52 can be parallel to the rotation axis of the wind deflector body 51, and the convex surface faces the curved plate of the wind deflector body 51, so as to better guide the upward air flow.

As shown in FIGS. 1 to 4 , the wind deflector body 51 is formed into an elongated shape whose longitudinal direction is parallel to the rotational axis direction thereof. The wind deflector 52 is a long strip extending along the longitudinal direction of the wind deflector body 51 , and both ends in the longitudinal direction of the wind deflector body 51 are spaced apart from both ends in the longitudinal direction of the wind deflector body 51 . That is to say, the length of the wind deflector 52 is shorter than that of the wind deflector body 51 , so that the two ends of the wind deflector body 51 in the longitudinal direction form a more unobstructed air outlet area and increase the air volume of the air outlet 12 . The length of the air deflector body 51 can be made equal to the length of the casing 10 of the wall-mounted air conditioner indoor unit, and longer than the air outlet 12 (the length of the air outlet is smaller than the length of the casing), so as to utilize the two end sections of the air deflector body 51 Covering the outer surface of the casing 10 makes the appearance of the wall-mounted air conditioner indoor unit more beautiful. In addition, the entire air deflector body 51 may be in the shape of a long arc-shaped plate with the first side surface 511 being a concave surface. Of course, the entire air deflector body 51 may also be a flat plate.

As shown in FIG. 1 and FIG. 2 , the wind deflector 50 may further include two end plates 523 . The two end plates 523 are respectively connected to the two ends of the wind deflector 52 along the rotation axis direction of the wind deflector body 51 and the second end plate 523 . Between one side surface 511 to close the interval between the two ends of the wind-raising plate 52 and the first side surface 511 . This can prevent the airflow from flowing in the direction of the rotation axis of the air deflector body 51, thereby avoiding the occurrence of unfavorable eddy currents and noise.

As shown in FIG. 1 and FIG. 2 , the wind deflector 50 may further include a plurality of connecting ribs 522 arranged at intervals along the parallel direction of the rotation axis of the wind deflector body 51 , and each connecting rib 522 connects the wind raising plate 52 and the wind guide Board body 51 to achieve structural connection. The extending directions of the plurality of connecting ribs 522 can be further made parallel to the flow direction of the supply air flow, so as to reduce the resistance of the connecting ribs 522 to the airflow. The wind-raising plate 52, the connecting rib 522 and the main body 51 of the wind-guiding plate can be integrally formed into an integral piece, which is convenient for processing and manufacturing.

In some embodiments, as shown in FIG. 1 to FIG. 4 , the air guide body 51 is provided with a drainage opening 515 penetrating through the air guide body 51 , and the drainage opening 515 penetrates through both sides of the air guide plate body 51 and is located opposite the air raising plate 52 . downstream side of the air flow. After the air supply air flows through the air blowing plate 52 , a negative pressure is formed at the first side 511 , thereby driving the ambient air on the second side (lower side) of the air deflector body 51 to flow into the air supply air through the drainage port 515 .

That is to say, since the air blowing plate 52 pushes the supply air flow away from the first side surface 511, the airflow density at the first side surface 511 of the air deflector body 51 is reduced, forming a negative pressure area (the S area in FIG. 4 roughly represents a negative pressure area). pressure area). Under the suction of the negative pressure area, the ambient air on the second side of the air deflector body 51 enters the negative pressure area through the drainage port 515 opened on the air deflector body 51, and then merges into the air supply airflow to form a mixed air effect . When the air conditioner is cooling, the mixing of ambient air into the air supply airflow can properly increase the temperature of the air supply airflow; when the air conditioner is heating, the mixing of ambient air can appropriately reduce the temperature of the air supply airflow, which makes the air supply airflow more comfortable and achieves Air-conditioned comfort.

The upstream edge of the airflow of the drainage opening 515 refers to the edge of the drainage opening 515 that is close to the windward end of the air deflector body 51, and the other side of the drainage opening 515 opposite to the upstream edge of the airflow (side C) is the downstream edge (side D) of the airflow, as shown in the figure 2 and Figure 3.

The blower plate 52 can be extended from the upstream edge (C side) of the air flow of the inflow port 515 . Also, the projection of the air blowing plate 52 on the first side 511 can cover at least the drainage opening 515, so as to prevent ambient air from entering the air supply airflow vertically through the drainage opening 515, causing problems such as excessive noise. Further, the end (E end) of the blower plate 52 in the direction of the airflow can be made to exceed the drainage opening 515 (referring to the downstream edge D of the airflow beyond the drainage opening 515), so as to define the relationship with the drainage opening 515 with the first side surface 511. Connected drainage channel 516 . The drainage channel 516 can guide the flow direction of the ambient air, so that when it merges with the supply air flow, the included angle between the two air flows is smaller, and the mixing is more gentle.

The utility model also provides a wall-mounted air conditioner indoor unit. FIG. 5 is a schematic view of the state of the wall-mounted air conditioner indoor unit shown in FIG. 4 after the air deflector is further opened.

As shown in FIG. 4 and FIG. 5 , the wall-mounted indoor unit of the air conditioner according to the embodiment of the present invention may generally include a housing 10 and an air guide plate 50 according to any of the above embodiments. The housing 10 is provided with an air inlet 11 and an air outlet 12 . The air deflector body 51 of the air deflector 50 is rotatably installed at the air outlet 12 .

In some embodiments, as shown in FIGS. 1 to 4 , the wind deflector 50 further includes at least one rotating arm 53 , one end of which is connected to the driving device 70 inside the housing 10 and the other end is connected to the wind deflector body 51 . Driven by the driving device 70 , the rotating arm 53 drives the air deflector body 51 to rotate upwardly around the first end of the rotating arm 53 to close the air outlet 12 , or rotate downward to open the air outlet 12 . A plurality of rotating arms 53 can be provided, so that the plurality of rotating arms 53 are arranged at intervals along the length direction of the air deflector body 51 . The driving device 70 includes a motor for directly or indirectly driving the rotating arm 53 to rotate.

As shown in FIG. 5 , the air outlet 12 can be located at the lower part of the front side of the casing 10 and opened forward and downward. The entire turning arm 53 is a bent arm with one bending and the bending opening is downward. The driving device 70 is installed at the bottom wall of the air duct 40 . The purpose of setting the curved arm is to make the first side 511 face the air outlet 12 at every angle of the air deflector 50 when the air outlet 12 is opened, so that the supply air flow is guided by the first side 511, and the second side 512 faces away from the air outlet 12. The air outlet 12 is in contact with the ambient air, which is beneficial to realize the air mixing function of the air deflector 50 . Moreover, the setting of the curved arm also facilitates the rotation of the air deflector body 51 to the lower side of the housing 10 so as to completely avoid the supply air flow from the air outlet 12, that is, to completely open the air outlet 12, so that the air deflector 50 does not block the airflow at all .

On this basis, one or more inner guide plates 80 can be additionally arranged at the air outlet 12 , and the inner guide plates 80 can be rotatably installed at the air outlet 12 and located inside the air guide plate 50 for adjusting the size of the air outlet 12 . Wind direction up and down. That is, the air guide plate 50 is made to play more functions of opening and closing the air outlet and air mixing, and the inner guide plate 80 is made to play the role of wind guide and up-down wind.

As shown in FIG. 4 , the wall-mounted air conditioner indoor unit may include an evaporator 20 , a fan 30 , an air duct 40 , and a swing blade 60 . The evaporator 20 is used to exchange heat with the air entering the casing 10 from the air inlet 11 to form a supply air flow (specifically, cold air during cooling and hot air during heating). The inlet of the air duct 40 faces the evaporator 20 , and the outlet communicates with the air outlet 12 . The blower 30 may be a cross-flow blower, which is disposed at the inlet of the air duct 40 to promote the flow of air from the evaporator 20 to the air outlet 12 . The swing blades 60 are used to swing the wind left and right.
