[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] Reference below Figure 1-Figure 16 A wall-mounted air conditioner indoor unit 100 according to an embodiment of the present invention is described, and the wall-mounted air conditioner indoor unit 100 can be used for cooling and heating indoor air.

[0049] like Figure 1-Figure 3 , Figure 6-Figure 10 As shown, a wall-mounted air conditioner indoor unit 100 according to an embodiment of the present invention includes: a casing 10 , a front air guide plate 20 , an indoor heat exchanger 60 , a main indoor fan 50 and two side fans 40 .

[0050] like Fig.16As shown, the indoor heat exchanger 60 is arranged in the casing 10, and the casing 10 may be provided with a middle air duct 140 and side air ducts (not shown in the figure) located on both sides of the middle air duct 140, and the front side of the casing 10 may be provided with a front air outlet 110 connected to the middle air duct 140, and the left and right side walls of the casing 10 may be respectively provided with side vents connected to the corresponding side air ducts. Specifically, a connecting air duct 150 may also be provided in the casing 10, and the connecting air duct 150 is located between the middle air duct 140 and the side air ducts on the left and right sides, thereby facilitating the circulation of air flow. When the wall-mounted air conditioner indoor unit 100 is working, the indoor air enters the casing 10 and first exchanges heat with the indoor heat exchanger 60, and a part of the air flow after heat exchange can be discharged from the front air outlet 110 through the middle air duct 140, and another part of the air flow after heat exchange can be discharged from the side vents on the left and right sides through the side air duct. Thus, the wall-mounted air conditioner indoor unit 100 can discharge air toward the front and the left and right sides at the same time, which can improve the air supply efficiency of the wall-mounted air conditioner indoor unit 100, and further improve the cooling and heating efficiency of the wall-mounted air conditioner indoor unit 100.

[0051] It is understandable that the opening and closing states of the front air outlet 110 and each side air outlet 120 of the wall-mounted air conditioner indoor unit 100 can be selected according to actual use requirements. For example, when the indoor temperature has been adjusted to a preset temperature, one or more of the front air outlet 110 and the side air outlet 120 can be closed, thereby reducing the energy consumption of the wall-mounted air conditioner indoor unit 100 without affecting the indoor temperature.

[0052] like Figure 6-Figure 10 As shown, the front air guide plate 20 is rotatably arranged at the front air outlet 110, and the rotation angle of the front air guide plate 20 can be controlled to control the air outlet direction and air volume of the front air outlet 110. For example, when the wall-mounted air conditioner indoor unit 100 is in cooling operation, in order to prevent the cold air from blowing directly to the indoor user, the front air guide plate 20 can be adjusted to make the cold air blow obliquely upward from the wall-mounted air conditioner indoor unit 100, or the front air guide plate 20 can be adjusted to completely close the front air outlet 110, and the cold air can be discharged through the side vents on the left and right sides. In this way, the cold air can slowly circulate in the indoor space in a top-down manner by relying on its own gravity, which can not only make the indoor temperature distribution more uniform, but also improve the user's comfort.

[0053] like Figure 15-16As shown, the main indoor fan 50 can be arranged in the middle air duct 140, and the two side fans 40 can be arranged in the two side air ducts respectively, and the direction of the two side fans 40 can be changed so that the side vents can be switched between the side air inlet 130 and the side air outlet 120, and when the side vents are the side air inlet 130, the airflow flowing in from the side air duct collides with the airflow in the middle air duct 140 at a position adjacent to the front air outlet 110. Specifically, the main indoor fan 50 can guide the air flow to circulate in the middle air duct 140, and the two side fans 40 can guide the air flow to circulate in the corresponding side air ducts, wherein the rotation direction of the two side fans 40 can be changed. For example, when the two side fans 40 rotate forward, the air flow in the housing 10 can be blown out from the side vents, and at this time, the side vents are the side air outlets 120. When the two side fans 40 rotate in reverse, the indoor air can be guided into the casing 10 through the side vents. In this case, the side vents are the side air inlets 130 .

[0054] The wall-mounted air conditioner indoor unit 100 can have a normal air outlet mode and a first windless mode. When the wall-mounted air conditioner indoor unit 100 is in the normal air outlet mode, the two side fans 40 rotate forward, the side vents are the side air outlets 120, and the front air guide plate 20 is opened. The wall-mounted air conditioner indoor unit 100 can discharge air in the front and left and right directions at the same time, which can improve the air supply efficiency of the wall-mounted air conditioner indoor unit 100. When the wall-mounted air conditioner indoor unit 100 is in the first windless mode, the two side fans 40 rotate inversely, the side vents are the side air inlets 130, and the front air guide plate 20 is opened. At this time, the main indoor fan 50 can guide the air flow after heat exchange to the front air outlet 110, and the two side fans 40 can guide the indoor air flow from the side air inlets 130 on the left and right sides to enter the side air duct at the same time. The two air flows enter the middle air duct 140 through the connecting air duct 150 and collide with the air flow that has completed heat exchange at a position near the front air outlet 110 in the middle air duct 140. As a result, the two air flows entering from the side air inlet 130 can be mixed with the air flow that has completed heat exchange, so that the temperature of the air flow that has completed heat exchange can be made more suitable, and the air flow can be prevented from being too cold / too hot and causing discomfort to the user. In addition, the two air flows entering from the side air inlet 130 can change the flow direction of the air flow that has completed heat exchange through collision, so that the air flow that has completed heat exchange can flow to multiple directions of the indoor space, thereby preventing the cold wind / hot wind from blowing directly to the indoor user, achieving a better windless effect, and improving the user's comfort.

[0055] According to the wall-mounted air conditioner indoor unit 100 of the embodiment of the present invention, by providing the front air outlet 110 and the left and right side air outlets 120, the wall-mounted air conditioner indoor unit 100 can blow air in multiple directions of the indoor space, thereby improving its cooling and heating efficiency. By providing the two side fans 40 with variable direction, not only can the temperature of the air flow be made more suitable, but also the flow direction of the air flow after the heat exchange is completed can be changed, thereby achieving a better windless effect and improving the user's comfort.

[0056] like Figure 1-Figure 2 , Figure 7 and Fig.10 As shown, according to some embodiments of the present invention, a plurality of first vents 210 may be provided on the front air guide plate 20, thereby improving the windless effect of the wall-mounted air conditioner indoor unit 100. Specifically, the wall-mounted air conditioner indoor unit 100 may have a second windless mode, that is, the front air guide plate 20 completely closes the front air outlet 110, and the two side fans 40 rotate forward. At this time, a part of the air flow after heat exchange is blown out through the left and right side air outlets 120, and another part of the air flow after heat exchange can flow to the indoor space through the plurality of first vents 210. Since the plurality of first vents 210 can be arranged at intervals, the diameters of the plurality of first vents 210 are small, and when the air flow passes through the plurality of first vents 210, the plurality of first vents 210 can play a role in reducing the circulation speed of the air flow. When the air flow flows out from the plurality of first vents 210, the circulation speed of the air flow is significantly reduced, thereby achieving the effect of windless feeling and improving the user's comfort. Optionally, the front air deflector 20 may be a metal member to improve the structural strength of the front air deflector 20 .

[0057] Of course, it is understandable that when the wall-mounted air conditioner indoor unit 100 is in the second windless mode, the two side fans 40 can also be reversed, thereby further improving the windless effect of the wall-mounted air conditioner indoor unit 100. For example, when the wall-mounted air conditioner indoor unit 100 is in cooling operation, since the air velocity of the cold air is fast, the temperature difference between the temperature of the cold air and the user's body surface temperature is large, the wall-mounted air conditioner indoor unit 100 can be adjusted to enter the second windless mode, and the two side fans 40 are reversed at the same time, thereby meeting the air supply demand while maximizing the windless effect of the wall-mounted air conditioner indoor unit 100, which can bring a better user experience to the user.

[0058] like Figure 2-Figure 5As shown, according to some embodiments of the present invention, a plurality of side air guide plates 30 may be provided at each side air outlet 120, whereby the plurality of side air guide plates 30 may disperse the air flow at the side air outlet 120, and prevent the air flow from the side air outlet 120 from blowing directly toward the user, thereby improving the body comfort of the air flow at the side air outlet 120. Optionally, each side air guide plate 30 may be a metal part, thereby improving the structural strength of the side air guide plate 30.

[0059] In some embodiments of the present invention, a plurality of side air guide plates 30 may be arranged at intervals in the vertical direction, thereby facilitating the control of the outlet angle of the air flow. Of course, it is understandable that the distribution of the plurality of side air guide plates 30 is not limited to this. Figure 3-Figure 5 As shown, a plurality of side air guide plates 30 may also be evenly spaced apart in the front-to-rear direction.

[0060] In some embodiments of the present invention, the side air guide plate 30 is rotatably disposed at the side air outlet 120, so that the air outlet direction and air volume of the side air outlet 120 can be easily adjusted. Figure 5 As shown, multiple side air guide plates 30 are evenly spaced in the front-to-back direction, and each side air guide plate 30 can rotate relative to the air outlet. Multiple side air guide plates 30 can change the air outlet direction and air volume of the side air outlet 120 by changing their own rotation angles. When multiple side air guide plates 30 rotate to an angle perpendicular to the air flow direction in the air outlet duct, the side air outlet 120 is completely closed, and when multiple side air guide plates 30 rotate to an angle parallel to the air flow direction in the air outlet duct, the side air outlet 120 is completely opened. It can be understood that, as Figure 4 As shown, the side air guide plate 30 can also be arranged to remain fixed relative to the side air outlet 120, so that the side air outlet 120 can blow air in one direction to meet specific usage requirements.

[0061] Optionally, the opening and closing and the opening angle of each side air guide plate 30 can be controlled separately, thereby improving the user's usage flexibility and enabling the wall-mounted air conditioner indoor unit 100 to meet various usage requirements. For example, when indoor users gather on the right side of the wall-mounted air conditioner indoor unit 100, the side air guide plates 30 at the left air outlet 120 can be controlled to be closed, and the side air guide plates 30 at the right air outlet 120 can be controlled to be opened, thereby enabling the wall-mounted air conditioner indoor unit 100 to blow concentrated air toward the right half of the indoor space, which can not only improve the user's usage comfort, but also reduce the energy consumption of the wall-mounted air conditioner indoor unit 100.

[0062] According to some embodiments of the present invention, a microporous air guide plate may be provided at each side air outlet 120, and a plurality of side micropores may be provided on the microporous air guide plate, thereby improving the windless effect of the wall-mounted air conditioner indoor unit 100. Specifically, when the wall-mounted air conditioner indoor unit 100 is in the windless mode, the microporous air guide plate partially or completely closes the side air outlet 120, and when the air flows out from the air outlet duct, the side micropores on the microporous air guide plate can reduce the circulation speed of the air flow. When the air flows out from the side micropores, its circulation speed is significantly reduced, thereby achieving the windless effect and improving the user's comfort.

[0063] like Figure 1 and Figure 6 As shown, according to some embodiments of the present invention, the side air outlet 120 can be composed of a plurality of second ventilation holes 310 provided on the casing 10, so as to enhance the windless effect of the wall-mounted air conditioner indoor unit 100. Specifically, a plurality of second ventilation holes 310 distributed at intervals can be provided on the side panel of the casing 10, and the plurality of second ventilation holes 310 can reduce the circulation speed of the air flow, so as to achieve the windless effect. Optionally, a plurality of second ventilation holes 310 can be provided on one side panel of the casing 10, and a microporous air guide plate can be provided on the other side panel of the casing 10, or a plurality of second ventilation holes 310 can be provided on both the left and right side panels of the casing 10, or a microporous air guide plate can be provided on both the left and right side panels of the casing 10, and the setting can be selected according to actual use requirements.

[0064] like Figure 1-Figure 2 As shown, according to some embodiments of the present invention, each first ventilation hole 210 can be formed as a circular hole, thereby making the structure of the front air deflector 20 simpler and more aesthetically pleasing. Optionally, the diameters of each first ventilation hole 210 can be the same or different, and can be selected and set according to design requirements. It is understandable that the shape of the first ventilation hole 210 is not limited thereto, and the first ventilation hole 210 can also be set as a rectangular hole, a polygonal hole, etc.

[0065] like Figure 11-Figure 14As shown, according to some embodiments of the present invention, a plurality of mounting through holes 220 may be provided on the front air guide plate 20, and a plurality of air guide blades 220A may be provided in each mounting through hole 220, and the inner ends of the plurality of air guide blades 220A are connected to each other, and the space between adjacent air guide blades 220A defines a first vent 210, thereby improving the windless effect of the wall-mounted air conditioner indoor unit 100. Specifically, a connecting column 240 may be provided in each mounting through hole 220, and the inner ends of the plurality of air guide blades 220A are simultaneously connected to the connecting column 240, thereby improving the structural firmness of the front air guide plate 20. Each air guide blade 220A may be formed in an arc shape, and the plurality of air guide blades 220A are arranged around the connecting column 240, thereby, the plurality of air guide blades 220A may form a circular air outlet space. Since the arcuate surface of each air guide blade 220A extends at a different angle, when the air flows through the mounting hole 220, the multiple air guide blades 220A can not only slow down the air flow speed, but also change the air flow direction. The air flow can slowly flow to multiple directions of the indoor space, thereby achieving a better windless effect. Optionally, the multiple mounting holes 220 can be evenly spaced in the left and right directions, thereby making the air supply of the front air outlet 110 more uniform. Optionally, as Fig.14 As shown, the diameter of each mounting through hole 220 may also be different and can be selected and set according to usage requirements.

[0066] like Figure 12-14 As shown, in some embodiments of the present invention, the plurality of first ventilation holes 210 may further include a plurality of ventilation micropores 230 distributed outside the mounting through hole 220, thereby improving the air supply efficiency of the wall-mounted air conditioner indoor unit 100. Specifically, the plurality of ventilation micropores 230 may increase the air outlet area of ​​the front air outlet 110. When the wall-mounted air conditioner indoor unit 100 is working, the air flow may simultaneously flow outward through the plurality of ventilation micropores 230 and the space between the two adjacent air guide blades 220A (the first ventilation holes 210), thereby not only achieving a windless effect, but also increasing the air outlet area of ​​the front air outlet 110, improving the air supply speed, and reducing the workload of the wall-mounted air conditioner indoor unit 100.

[0067] like Figure 7-10 As shown, according to some embodiments of the present invention, the front air guide plate 20 may include a first air guide plate 20A and a second air guide plate 20B, and the first air guide plate 20A and the second air guide plate 20B may be provided with a plurality of first ventilation holes 210, the first air guide plate 20A is located at the upper part of the second air guide plate 20B, and the second air guide plate 20B is rotatably arranged on the bottom wall of the air outlet duct, and in the first windless mode, the lower end of the first air guide plate 20A cooperates with the upper end of the second air guide plate 20B, thereby making the structure of the front air guide plate 20 simpler and convenient to adjust the air outlet direction and air volume of the front air outlet 110.

[0068] Specifically, the first air guide plate 20A and the second air guide plate 20B can both rotate relative to the housing 10, thereby adjusting the air volume and air direction of the front air outlet 110. Figure 8 As shown, when the wall-mounted air conditioner indoor unit 100 is in the normal air outlet mode, the first air guide plate 20A and the second air guide plate 20B are rotated to an angle parallel to the air flow direction in the air outlet duct. At this time, the air outlet area of ​​the front air outlet 110 is the largest, and the air flow can be directly blown into the indoor space through the front air outlet 110. Fig.10 As shown, when the wall-mounted air-conditioning indoor unit 100 is in the first windless mode, the second air guide plate 20B is rotated so that its upper end cooperates with the lower end of the first air guide plate 20A, thereby completely closing the front air outlet 110, and the air flow can pass through the multiple first ventilation holes 210 on the first air guide plate 20A and the second air guide plate 20B to enter the indoor space.

[0069] It is understandable that the air outlet direction of the front air outlet 110 can be adjusted by controlling the first air guide plate 20A and the second air guide plate 20B to rotate to different angles. For example, when the wall-mounted air conditioner indoor unit 100 performs cooling work, in order to prevent the cold air from blowing directly to the indoor user, the first air guide plate 20A and the second air guide plate 20B can be adjusted to make the front air outlet 110 blow air diagonally upward, so that the low-temperature air flow can slowly circulate from top to bottom in the indoor space by its own gravity, which can not only improve the windless effect, but also make the indoor temperature distribution more uniform.

[0070] The air conditioner according to the embodiment of the present invention includes the wall-mounted air conditioner indoor unit 100 according to the above-mentioned embodiment of the present invention.

[0071] According to the air conditioner of the embodiment of the present invention, by setting the above-mentioned wall-mounted air conditioner indoor unit 100, the wall-mounted air conditioner indoor unit 100 is provided with a front air outlet 110 and left and right side air outlets 120, so that the wall-mounted air conditioner indoor unit 100 can blow air in multiple directions of the indoor space, and its cooling and heating efficiency can be improved. The two side fans 40 in the wall-mounted air conditioner indoor unit 100 can be turned in a variable direction, which can not only make the temperature of the air flow more suitable, but also change the flow direction of the air flow after the heat exchange is completed, thereby achieving a better windless effect, improving the user's comfort, and further improving the practical performance of the air conditioner.

[0072] Reference below Figure 2-Figure 3 , Figure 5-Figure 10 , Figure 12-13 and Figure 15-16The wall-mounted air conditioner indoor unit 100 according to a specific embodiment of the present invention is described in detail. The wall-mounted air conditioner indoor unit 100 can be used for cooling and heating indoor air. It is worth noting that the following description is only exemplary and not a specific limitation of the present invention.

[0073] like Figure 2-Figure 3 , Figure 6-Figure 10 , Figure 15-16 As shown, the wall-mounted air conditioner indoor unit 100 includes: a casing 10, a front air guide plate 20, a side air guide plate 30, an indoor heat exchanger 60, a main indoor fan 50 and two side fans 40. Among them, a middle air duct 140 and side air ducts located on both sides of the middle air duct 140 are provided in the casing 10, and a connecting air duct 150 is provided between the middle air duct 140 and the side air ducts on the left and right sides. A front air outlet 110 is provided at the lower front part of the casing 10, and side vents are respectively provided on the left and right side walls of the casing 10. The middle fan is arranged opposite to the front air outlet 110, and the two side fans 40 are arranged opposite to the two side air outlets 120 respectively.

[0074] like Figure 7-10 As shown, the front air guide plate 20 includes a first air guide plate 20A and a second air guide plate 20B. The first air guide plate 20A is located above the second air guide plate 20B. The first air guide plate 20A and the second air guide plate 20B can both rotate relative to the housing 10. Figure 11-Figure 14 As shown, the first air guide plate 20A and the second air guide plate 20B are both provided with a plurality of mounting through holes 220 and a plurality of ventilation micro holes 230 distributed outside the mounting through holes 220. A connecting column 240 and a plurality of air guide blades 220A are provided in each mounting through hole 220, and each air guide blade 220A is formed in an arc shape, and the inner ends of the plurality of air guide blades 220A are connected to the connecting column 240 and are arranged around the connecting column 240, thereby forming a circular air outlet space with the plurality of air guide blades 220A.

[0075] like Figure 2-Figure 3 , Figure 5 As shown, each side air outlet 120 is provided with a plurality of side air guide plates 30, and the plurality of side air guide plates 30 are evenly spaced in the front-to-back direction, and each side air guide plate 30 can be rotated relative to the air outlet, and the plurality of side air guide plates 30 can change the air outlet direction and air outlet volume of the side air outlet 120 by changing their own rotation angle.

[0076] Specifically, when the wall-mounted air conditioner indoor unit 100 performs cooling work, in order to prevent the cold wind from blowing directly to the indoor user, the wall-mounted air conditioner indoor unit 100 is adjusted to the second windless mode, the two side fans 40 are reversed, and the side vents are the side air inlets 130. The first air guide plate 20A and the second air guide plate 20B rotate simultaneously and make the upper end of the second air guide plate 20B cooperate with the lower end of the first air guide plate 20A, and the front air outlet 110 is completely closed. The multiple side air guide plates 30 at each side air inlet 130 rotate to an angle parallel to the air flow direction in the air outlet duct, and the side air inlet 130 is fully opened. The main indoor fan 50 guides the air flow after heat exchange to the front air outlet 110, and the two side fans 40 guide the indoor air flow to enter the side air duct from the left and right side air inlets 130 at the same time. The two air flows enter the middle air duct 140 through the connecting air duct 150 and collide with the air flow that has completed heat exchange in the middle air duct 140. Then the mixed air flows into the indoor space through the space between the two adjacent air guide blades 220A (the first ventilation hole 210). In this way, not only can the temperature of the air flow be made more suitable, but also a better windless effect can be achieved, thereby improving the user's comfort.

[0077] When the wall-mounted air conditioner indoor unit 100 is heating, since the density of hot air is small and the circulation speed is slow, the wall-mounted air conditioner indoor unit 100 is adjusted to the first windless mode, the two side fans 40 rotate forward, and the side vents are side air outlets 120. The first air guide plate 20A and the second air guide plate 20B rotate simultaneously and make the upper end of the second air guide plate 20B cooperate with the lower end of the first air guide plate 20A, and the front air outlet 110 is completely closed. The multiple side air guide plates 30 at each side air outlet 120 rotate to an angle parallel to the air flow direction in the air outlet duct, and the side air outlet 120 is fully opened. The hot air is blown out through the space between the two adjacent air guide blades 220A (the first ventilation hole 210) and the side air outlets 120 on the left and right sides at the same time. In this way, a better windless effect can be achieved without affecting the air supply efficiency.
