The utility model provides a wall-mounted air conditioner indoor unit, which can realize conventional air outlet and wind-free air outlet. And in the no-wind-sensing air-out mode, the air volume loss of the wall-mounted air conditioner indoor unit is less, and a larger air volume can be maintained.

Referring to FIG. 1 , in an embodiment of the wall-mounted air conditioner indoor unit of the present invention, the wall-mounted air conditioner indoor unit includes a casing 100 and an air guide plate 400 . The housing 100 includes a chassis 110 and a front panel 120 , an air outlet 102 is provided at the bottom of the housing 100 , and an air inlet 101 communicated with the air outlet 102 is provided on the front panel 120 . The air deflector 400 is rotatably connected to the lower side of the air outlet 102, and the air deflector 400 can be switched between a closed state, a first open state, and a second open state when the air deflector 400 is rotated. in:

Referring to FIG. 1 , in the closed state, the air deflector 400 covers the air outlet 102 .

Referring to FIG. 2 , in the first open state, the air deflector 400 is located at the lower side of the air outlet 102 , and the air outlet 102 guides the airflow downward.

Referring to FIG. 3 , in the second open state, the air deflector 400 is located at the front side of the air outlet 102 and is inclined toward the air inlet 101 , so that the air flow derived from the air deflector 400 flows back from the air inlet 101 .

Specifically, the air inlet 101 and the air outlet 102 both extend along the length direction of the casing 100 . The housing 100 also has a heat exchange air duct 103 , and the heat exchange air duct 103 communicates the air inlet 101 and the air outlet 102 . The heat exchanger 200 and the cross-flow wind wheel 300 of the wall-mounted air conditioner indoor unit are installed in the heat exchange air duct 103 , and the heat exchanger 200 is arranged in a semi-surrounding manner of the cross-flow wind wheel 300 . The heat exchange air duct 103 is also provided with a louver 600 for adjusting the air supply direction of the air outlet 102 .

When the indoor unit of the wall-mounted air conditioner is not working, the wind deflector 400 is in a closed state. When the wall-mounted air conditioner indoor unit is in operation, the air deflector 400 is opened, the air deflector 400 is in the first open state or the second open state, the cross-flow wind wheel 300 rotates at a high speed, and drives the outside air to enter the housing 100 from the air inlet 101 Inside, after heat exchange by the heat exchanger 200 , it continues to be driven by the cross-flow fan 300 and blows out from the air outlet 102 . Therefore, by switching the air deflector 400 between the first open state and the second open state, two modes of normal air supply and windless air supply of the wall-mounted air conditioner indoor unit can be realized. The details are as follows:

Referring to FIG. 2 , if the air deflector 400 is switched to the first open state, in this state, since the air deflector 400 is located on the lower side of the air outlet 102 , that is, the air deflector 400 is away from the air outlet 102 , and expose the air outlet 102 as a whole. The cold air or hot air blown out from the air outlet 102 will maintain the inertia of the original downward flow and be directly blown to the middle and lower space of the indoor environment, thereby contributing to rapid cooling or heating and realizing conventional air supply.

Referring to FIG. 3 , if the wind deflector 400 is switched to the second open state, in this state, the front side of the air outlet 102 is blocked by the wind deflector 400 . The cold air or hot air blown out from the air outlet 102 is blocked by the wind deflector 400 , and will flow toward the upper space of the indoor environment along the deflection direction of the wind deflector 400 . When reaching the vicinity of the air inlet 101 , under the suction of the negative pressure of the air inlet 101 , the air flows back from the air inlet 101 to the heat exchange air duct 103 inside the casing 100 .

That is to say, in the second open state, a self-circulation loop is formed in which air enters from the air inlet 101 , and returns to the air inlet 101 through the heat exchange air duct 103 and the air outlet 102 in sequence. During the flow of cold air or hot air along the self-circulation loop, the airflow exchanges heat with the indoor environment by means of radiation, and does not form strands of wind blowing toward the user. This kind of radiative heat exchange is relatively gentle and soft, so as to achieve windless air supply.

In the technical solution of the present invention, by arranging the air inlet 101 on the front panel 120 of the housing 100, and rotatingly connecting the air deflector 400 with the lower side of the air outlet 102, the air deflector 400 can be used in the first open state. Switching between the second open state and conventional air supply and windless air supply can be realized. For details, refer to the foregoing description, which is not repeated here. When the air is supplied without wind sense, the air exchanges heat with the indoor environment through radiation during the circulating flow of the self-circulation loop, thereby avoiding the wind blowing to the user in strands, greatly reducing the intensity of the wind sense, and then Achieve windless.

In addition, since the air inlet 101 is provided on the front panel 120 , the dust in the environment is not easy to fall directly onto the air inlet 101 , thereby reducing the return journey from the air inlet 101 into the heat exchange air duct 103 .

Referring to FIG. 3 and FIG. 4 , based on the above embodiment, when the air deflector 400 is in the second open state, the indoor unit of the wall-mounted air conditioner is in a windless air supply mode. In this state, the larger the air flow rate passing through the self-circulation loop, the stronger the radiation heat exchange efficiency. Therefore, in an embodiment, in the second open state, the air deflector 400 can cover the lower part of the air outlet 102, so that the air flow of the heat exchange air duct 103 flows upward from the upper part of the air outlet 102 to prevent This increases the amount of air flowing from the circulation loop and enhances the radiative heat transfer effect.

Theoretically speaking, in the second open state, the wind deflector 400 is arranged in an inclined shape, and the larger the angle between the wind deflector 400 and the horizontal plane, the more favorable it should be to guide the airflow from the air outlet 102 upward. However, studies have found that the larger the angle between the air guide plate 400 and the horizontal plane is, the smaller the opening between the upper edge of the air outlet 102 and the air guide plate 400 is. With the continuous convergence of the air flow at the air outlet 102, the air pressure at the air outlet 102 becomes larger, and the larger air pressure will directly eject the air flow forward from the opening at a larger wind speed, which will cause the air flow to deviate from the self-circulation loop, It is not easy to flow back from the air inlet 101 . It can be seen that in the second open state, the angle between the wind deflector 400 and the horizontal plane should be kept within a certain range.

It is found through research that in the second open state, the angle formed between the wind deflector 400 and the horizontal plane is not less than 30° and not more than 60°. As shown in FIGS. 3 and 4 , θ is represented as the angle formed by the wind deflector 400 and the horizontal plane. That is, 30°≤θ≤60°. As for the value of θ, it can be but not limited to: 30°, 35°, 38°, 40°, 45°, 47°, 50°, 55°, 60°. It should be noted that the angle θ formed by the wind deflector 400 and the horizontal plane should be the angle formed by the connecting line between the upper edge and the lower edge of the wind deflector 400 and the horizontal plane.

When there is no wind, the air deflector 400 is rotated to the second open state. Within this range, it can be ensured that when the opening between the upper edge of the air outlet 102 and the air deflector 400 is relatively large, the air deflector 400 can be blown out. More airflow will be directed upwards from the opening to prevent the airflow from being blown out while ensuring sufficient airflow, and to avoid the airflow from accumulating in the air outlet 102, thereby preventing the air pressure in the air outlet 102 from rapidly increasing and rapidly ejecting the airflow from the opening. Out of the situation occurs.

Referring to FIG. 3 and FIG. 4 , theoretically, the air inlet 101 may be formed on the upper or middle or upper middle or upper portion of the front panel 120 . However, the position of the air inlet 101 is actually related to the position from which the heat exchanger 200 enters. For example, when the air inlet 101 is located at a low position, the air entering from the air inlet 101 may not easily reach the top of the heat exchanger 200, thereby causing the heat exchange surface on the top of the heat exchanger 200 not to perform heat exchange and reducing the heat exchange efficiency.

Therefore, in order to avoid the above problems, the air inlet 101 is provided on the upper part of the front panel 120, so that the air inlet 101 is closer to the top of the heat exchanger 200, thereby ensuring that more air can enter from the heat exchanger 200 as a whole. , increase the heat exchange surface and improve the heat exchange efficiency.

Please refer to FIG. 4 and FIG. 5 , it is also considered here that the heat exchanger 200 includes a front heat exchanger 210 and a rear heat exchanger 220 , and the front heat exchanger 210 and the rear heat exchanger 220 are arranged at an angle, so as to surround the Cross-flow wind wheel 300. The angle position of the front heat exchanger 210 and the rear heat exchanger 220 forms the top of the heat exchanger 200 . Since the rear heat exchanger 220 faces away from the air inlet 101 , the air entering from the air inlet 101 may be blocked by the included angle position, making it difficult to enter the upper surface of the rear heat exchanger 220 and the back of the casing 100 In the cavity between the plates, it is easy to occur that the rear heat exchanger 220 has no wind to pass through, resulting in the failure of the rear heat exchanger 220 .

In one embodiment, in order to solve the above problem, the upper edge of the air inlet 101 may be set higher than the angle between the front heat exchanger 210 and the rear heat exchanger 220 . There is a first vertical height difference between the upper edge of the air inlet 101 and the included angle position (the first vertical height difference is shown as Δh ₁ in FIG. 5 ). In this way, the air entering from the air inlet 101 can pass through the angle position of the heat exchanger 200, and then disperse and fall to the front heat exchanger 210 and the rear heat exchanger 220, so that the front heat exchanger 210 and the rear The heat exchanger 220 has more air volume passing through, ensuring that both the front heat exchanger 210 and the rear heat exchanger 220 can perform effective heat exchange, thereby improving the heat exchange efficiency.

Further, the top plate 130 of the casing 100 can also be inclined upward from the rear to the front, so that the rear end of the top plate 130 is lower than the front end thereof. As a result, the air entering from the air inlet 101 will flow along the inclined direction of the rear end of the top plate 130 , and the airflow will flow between the upper surface of the rear heat exchanger 220 and the back plate of the casing 100 under the guidance of the top plate 130 . In the cavity, the air volume passing through the rear heat exchanger 220 is further increased.

In addition, since the heat exchange surface of the front heat exchanger 210 is larger than that of the rear heat exchanger, more air volume should be sent to the front heat exchanger 210 for heat exchange. To this end, the lower edge of the air inlet 101 can be set below the included angle position. That is, there is a second vertical height difference between the lower edge of the air inlet 101 and the included angle position (this vertical height difference is shown as Δh ₂ in FIG. 5 ). Therefore, more air entering from the lower part of the air inlet 101 falls on the front heat exchanger 210 , thereby improving the heat exchange efficiency of the front heat exchanger 210 .

Please continue to refer to FIG. 4 and FIG. 5. In FIG. 5, h ₀ represents the distance from the upper edge of the air inlet 101 to the upper edge of the air outlet, and h ₁ represents the distance from the lower edge of the air inlet 101 to the upper edge of the air outlet 102. . It should be noted that the "distance" should be the vertical distance along the up and down direction. The difference between h ₀ and h ₁ is the width of the air inlet 101 in the up-down direction. The sizes of h ₀ and h ₁ are not limited here. However, it is considered that when _h1 is too large, the width of the air inlet 101 will be limited, the air inlet surface of the air inlet 101 will be correspondingly smaller, the air intake volume will be limited, and the heat exchange efficiency will not be guaranteed. However, if _h1 is too small, in the state of no wind, the path of the airflow returning from the air outlet 102 to the air inlet 101 will be shortened accordingly, and the radiation heat exchange time of the air passing through this path will be shortened accordingly, and the heat exchange will be insufficient, and the heat exchange will be shortened accordingly. The effect is not guaranteed. It can be seen that h ₀ should maintain a certain ratio with h ₁ .

In view of this, in an embodiment, the ratio of the distance between the upper edge of the air inlet 101 to the upper edge of the air outlet 102 and the distance between the lower edge of the air inlet 101 and the upper edge of the air outlet 102 is not less than 2 , and not greater than 4. That is, h ₀ /h ₁ is not less than 2 and not more than 4. In other words, h ₀ /4≦h ₁ ≦h ₀ /2. h ₁ may be, but is not limited to: h ₁ equals h ₀ /4 or h ₀ /3 or h ₀ /2.

This design can ensure that h ₀ and h ₁ are kept in a better ratio, so that the width of the air inlet 10 will not be too large or too small, that is, the air intake volume of the air inlet 101 can be ensured, and the path of the air return can be extended. , to improve the radiation heat transfer efficiency.

Referring also to FIG. 4 and FIG. 5 , based on any of the above-mentioned embodiments, the structure of the front panel 120 may also be improved in the windless air supply mode. In one embodiment, the front panel 120 has a first wall surface 121 close to the upper edge of the air outlet 102 , and the first wall surface 121 is inclined from bottom to top toward the front. In this way, the lower end of the first wall surface 121 can be recessed toward the inside of the air outlet 102 , so that the air blown out from the air outlet 102 flows upwards in a windless air supply mode, and then follows the inclination direction of the first wall surface 121 . The Coanda flows with less flow resistance, which helps more airflow to flow from the self-circulation path to the air inlet 101 .

In the above embodiment, when the air flowing from the inclined direction of the first wall surface 121 is close to the air inlet 101, it still has a tendency to move forward and upward, and it is not easy to change the original inertia and enter the air inlet 101 easily. This results in a reduction in the air volume in the self-circulation path.

In view of this, in one embodiment, the front panel 120 further has a second wall surface 122 connected to the first wall surface 121 and the lower edge of the air inlet 101 , and the second wall surface 122 is inclined from bottom to top toward the rear. The second wall surface 122 is smoothly connected with the first wall surface 121 . When the air flowing from the Coanda in the inclined direction of the first wall surface 121 will flow along the Coanda wall of the second wall surface 122, the flow direction of the air flow is changed by the second wall surface 122, and the air flow is guided to flow towards the lower edge of the air inlet 101, Further, it can accurately enter the heat exchange air duct 103 of the casing 100 from the air inlet 101 .

Referring to FIG. 5 , in an embodiment, considering that in the air supply mode without wind feeling, when the air flow from the air outlet 102 flows along the self-circulation loop, the temperature on the inner and outer sides of the front panel 120 is different. , condensation water may be generated on the inner wall surface of the front panel 120 . If this part of the condensed water overflows to the air outlet 102, the phenomenon of water blowing is likely to occur.

In order to avoid the above situation, a water receiving groove 500 is provided below the front heat exchanger 210 . The water receiving groove 500 has a drainage plate 510 inclined toward the front panel 120 , and the upper edge of the drainage plate 510 overlaps with the inner side of the front panel 120 catch. When condensed water is generated on the inner wall surface of the front panel 120 , the condensed water flows downward, and will be led to the water receiving tank 500 along the drainage plate 510 , and then discharged from the water receiving tank 500 through the drain pipe.

The utility model also provides an air conditioner, which includes an air conditioner outdoor unit and a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit is connected to the air conditioner outdoor unit through a refrigerant pipe. The specific structure of the wall-mounted air conditioner indoor unit refers to the above embodiments. Since the wall-mounted air conditioner indoor unit adopts all the technical solutions of the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments. I won't go into details here.
