[0035] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art may adjust them as needed to suit specific applications.

[0036] Secondly, it should be noted that in the description of the present invention, terms such as "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0037] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0038] A cabinet air conditioner of the related art has an indoor unit comprising an outer shell and a cross-flow fan component disposed inside the outer shell, the outer shell being provided with an air-conditioning air inlet and an air-conditioning air outlet, the cross-flow fan component comprising a fan casing and a wind wheel disposed inside the fan casing, the fan casing having a fan air inlet disposed opposite to the air-conditioning air inlet, and a fan air outlet duct disposed opposite to the air-conditioning air outlet. When the wind wheel rotates, indoor air enters the fan casing from the air-conditioning air inlet through the fan air inlet, and is discharged from the air-conditioning air outlet through the fan air outlet duct, forming an air flow. However, the flow velocity of the air flow is the same at any position of the above-mentioned air-conditioning air outlet, and the air pressure of the indoor air discharged corresponding to any position of the air-conditioning air outlet is roughly the same, and the air outlet effect cannot achieve the effect of natural wind.

[0039] In order to solve the problem in the related art that the air outlet effect of the air-conditioning indoor unit of a cabinet air-conditioning cannot achieve the natural wind effect, the cabinet air-conditioning indoor unit of an embodiment of the present invention sets the air guide surface of at least part of the multiple transverse air guide plates to gradually increase along the first direction, so that when the air flow passes through the air guide surfaces of different transverse air guide plates, the flow speed of the air flow is different, and thus the air pressure of the indoor air near the air-conditioning outlet is distributed differently along the first direction. Under the action of the air pressure difference, the air near the air-conditioning outlet in the room naturally flows from the high-pressure position to the low-pressure position, simulating the air outlet effect of natural wind, and improving people's experience of air conditioning.

[0040] The cabinet air conditioner indoor unit of the embodiment of the present invention usually needs to work together with the cabinet air conditioner indoor unit used in conjunction with it, wherein the cabinet air conditioner indoor unit is usually placed indoors when in use, and the cabinet air conditioner outdoor unit is usually placed outdoors when in use.

[0041] See also Figure 1 and Figure 2 The cabinet air-conditioning indoor unit of an embodiment of the present invention includes an air outlet component 100, an air inlet component, a crossflow fan component 200 and an air guide plate component 300. The air inlet component and the air outlet component 100 are connected and enclose a accommodating cavity. The air inlet component and the air outlet component 100 are used to form a space for accommodating the crossflow fan component 200 and the air guide plate component 300, and to protect the crossflow fan component 200 and the air guide plate component 300. The crossflow fan component 200 is used to form an airflow so that air can circulate in and out of the accommodating cavity and cooperate with the heat exchanger of the cabinet air-conditioning indoor unit to perform cooling, heating or dehumidification. The air guide plate component 300 is used to adjust the direction of the airflow blown out by the air conditioner.

[0042] The air outlet component 100 and the air inlet component are described in detail below with reference to the accompanying drawings.

[0043] The cabinet-type air-conditioning indoor unit of an embodiment of the present invention also includes a base, a top cover arranged opposite to the base, and a column arranged between the base and the top cover. The air outlet component 100 and the air inlet component can be arranged on the column, and the air outlet component 100 and the air inlet component are connected and enclose an accommodating cavity.

[0044] See also Figure 1 、 Figure 2 as well as Figure 3 The air inlet component is provided with an air-conditioning air inlet, which can be a plurality of grille holes, and the air outlet component 100 is provided with an air-conditioning air outlet 101. When the cross-flow fan component 200 is running, the indoor air enters the accommodating cavity through the air-conditioning air inlet. After the air entering the accommodating cavity passes through the cross-flow fan component 200, it is discharged back into the room from the air-conditioning air outlet 101.

[0045] The crossflow blower component 200 will be described in detail below with reference to the accompanying drawings.

[0046] See also Figure 4 The cross-flow fan component 200 is arranged in the accommodating cavity. The cross-flow fan component 200 includes a fan casing 201 and a wind wheel. The fan casing 201 is used to provide an installation space and an installation reference for the wind wheel, and the wind wheel is used to drive the air flow.

[0047] See also Figure 4The fan housing 201 includes an installation cavity 202, and a fan air inlet 203 and a fan air outlet 204 connected to the installation cavity 202. The fan air inlet 203 is arranged opposite to the air inlet of the air conditioner, and the first end of the fan air outlet 204 away from the wind wheel is arranged opposite to the air outlet 101 of the air conditioner.

[0048] The wind wheel is arranged in the installation cavity 202, and the two ends of the wind wheel are rotatably connected to the fan casing 201. The cross-flow fan component 200 also includes a second motor for driving the wind wheel to rotate. The second motor is installed on the fan casing 201. The motor shaft of the second motor is transmission-connected to the wind wheel. When the second motor is running, the wind wheel rotates, and the air flow enters the installation cavity 202 from the air inlet of the air conditioner through the fan air inlet 203. After being driven by the wind wheel, it passes through the fan outlet 204 and is discharged from the air outlet 101 to the room.

[0049] Taking the vertical plane of the air outlet direction of the fan outlet duct 204 as the cross section, the cross section of the fan housing 201 at the position of the fan outlet duct 204 is a ring-shaped trapezoidal frame, the height direction of the trapezoidal frame is parallel to the first direction, the first direction is parallel to the center line of the wind wheel, and the first direction is as follows: Figure 2 In the X direction shown, the width of the trapezoidal frame gradually increases along the first direction. When the wind wheel rotates, when the airflow passes through the fan outlet duct 204 at the position where the trapezoidal frame width is wider, the airflow speed corresponding to the position where the trapezoidal frame width is wider is smaller, and the corresponding indoor air pressure close to the position where the trapezoidal frame width is wider is smaller. When the airflow passes through the fan outlet duct 204 at the position where the trapezoidal frame width is smaller, the airflow speed corresponding to the position where the trapezoidal frame width is narrower is greater, and the corresponding indoor air pressure close to the position where the trapezoidal frame width is narrower is greater. In this way, the air near the position of the air-conditioning outlet 101 in the room can flow naturally from the high-pressure position to the low-pressure position more quickly, the simulated natural wind outlet effect is better, and people have a better experience of blowing air with the air conditioner.

[0050] See also Figure 2 and Figure 4 The fan housing 201 includes a first mounting plate 205, a second mounting plate 206, a volute 207, and a volute tongue 208. The first mounting plate 205 and the second mounting plate 206 are arranged opposite each other. The mounting frame 301, the volute 207, and the volute tongue 208 are all installed between the first mounting plate 205 and the second mounting plate 206. The mounting frame 301 is located on one side of the volute tongue 208, and the mounting frame 301 and the volute tongue 208 are both arranged opposite the volute 207. The mounting frame 301, the volute tongue 208, the volute 207, the first mounting plate 205, and the second mounting plate 206 collectively enclose the installation cavity 202, as well as the fan outlet 204 and the fan inlet 203 correspondingly connected to the installation cavity 202. The mounting frame 301 constitutes part of the side wall of the fan outlet 204, which is a clever structure and can save material costs.

[0051] See also Figure 4 The fan housing 201 has two mounting cavities 202, two fan inlets 203, two fan outlets 204, and two impellers. Each fan inlet 203 and each fan outlet 204 communicate with a corresponding mounting cavity 202, and each impeller is disposed within a corresponding mounting cavity 202. The two fan inlets 203 are positioned opposite the air conditioner inlet, and the first ends of the two fan outlets 204 are positioned opposite the air conditioner outlet 101. The formation of two mounting cavities 202, two fan inlets 203, two fan outlets 204, and two impellers on the fan housing 201 enhances the ability of the crossflow fan assembly 200 to drive airflow.

[0052] See also Figure 2 and Figure 4 The fan casing 201 further includes a partition 209, a first mounting plate 205, a second mounting plate 206, and a partition 209, each of which has one volute 207 and two volute tongues 208. One side of each volute 207 is connected to one side of the partition 209. The two volute tongues 208 are located on both sides of the partition 209. The two wind wheels are located on both sides of the partition 209 and are respectively arranged in the corresponding mounting cavities 202. Each volute tongue 208 and the following mounting frame 301 in each wind deflector component 300 are connected to The corresponding volutes 207 are arranged relatively to each other, and the first mounting plate 205, the second mounting plate 206, the partition 209, and the volutes 207, the volute tongue 208 and the mounting frame 301 located on one side of the partition 209 and arranged relatively to each other enclose an installation cavity 202, and a fan outlet duct 204 and a fan inlet 203 corresponding to the installation cavity 202. The two installation cavities 202, the two fan inlets 203 and the two fan outlet ducts 204 formed in this way have a more compact structure and occupy a smaller volume of the accommodating cavity.

[0053] The air guide plate component 300 will be described in detail below with reference to the accompanying drawings.

[0054] See also Figure 2 and Figure 4 The wind guide plate component 300 is located at the second end of the fan outlet duct 204 close to the wind wheel. The wind guide plate component 300 includes a mounting frame 301 set on the fan casing 201, and a plurality of transverse wind guide plates 302 rotatably connected to the mounting frame 301. The mounting frame 301 is used to provide an installation reference for the transverse wind guide plates 302, and the transverse wind guide plates 302 are used to guide the flow direction of the airflow.

[0055] See also Figure 2, multiple transverse wind guide plates 302 are arranged along a first direction, and the wind guide surfaces of at least three of the multiple transverse wind guide plates 302 gradually increase along the first direction. The first direction can be the direction from the base to the top cover, or the direction from the top cover to the base. At least three of the multiple transverse wind guide plates 302 can be three close to each other, or three spaced apart. For example, the number of the multiple transverse wind guide plates 302 is four, and from the base to the top cover, they are the first transverse wind guide plate, the second transverse wind guide plate, the third transverse wind guide plate, and the fourth transverse wind guide plate, respectively. The at least three transverse wind guide plates 302 can be the first transverse wind guide plate, the second transverse wind guide plate, and the third transverse wind guide plate, or the first transverse wind guide plate, the second transverse wind guide plate, and the fourth transverse wind guide plate.

[0056] In the cabinet-type air-conditioning indoor unit of an embodiment of the present invention, when the air guide surfaces of at least three of the multiple transverse air guide plates 302 gradually increase along the first direction, the flow speed of the air flow is different when the air flow flows through the air guide surfaces of different transverse air guide plates 302, which makes the indoor air pressure at the position near the air-conditioning outlet 101 different along the first direction, and gradually increases along the first direction. In this way, the indoor air near the air-conditioning outlet 101 will naturally flow from the high-pressure position to the low-pressure position under the action of the air pressure difference, simulating the wind outlet effect of natural wind, thereby making people have a better experience of air conditioning.

[0057] exist Figure 2 In the illustrated embodiment, the air guiding surfaces of all the transverse air guide plates 302 among the multiple transverse air guide plates 302 gradually increase along the first direction. In this way, the air pressure difference of the indoor air at different positions near the air-conditioning outlet 101 along the first direction can be greater, thereby allowing the air at different positions near the air-conditioning outlet 101 in the room to flow naturally from the high-pressure position to the low-pressure position more quickly, resulting in a better simulated natural wind outlet effect and a better experience for people of blowing air with air conditioning.

[0058] See also Figure 1 and Figure 5 The lateral air guide plate 302 is provided with ribs 303 on the air guide surface, and the number of the ribs 303 provided on the multiple lateral air guide plates 302 gradually increases along the first direction. When the number of the ribs 303 provided on the lateral air guide plates 302 is larger, the flow rate of the airflow passing through the lateral air guide plates 302 is smaller, and the corresponding indoor air pressure at a position close to the air-conditioning outlet 101 is lower. In this way, the air pressure difference of the indoor air at different positions close to the air-conditioning outlet 101 along the first direction can be larger, and the indoor air at different positions close to the air-conditioning outlet 101 can flow naturally from the high-pressure position to the low-pressure position more quickly, the simulated natural wind outlet effect is better, and people have a better experience of blowing air with air conditioning.

[0059] See also Figure 1 and Figure 5 The height of the ribs 303 provided on the multiple transverse air guide plates 302 can also gradually increase along the first direction. When the height of the ribs 303 provided on the transverse air guide plates 302 is greater, the flow rate of the air passing through the transverse air guide plates 302 is smaller, and the corresponding indoor air pressure near the air-conditioning outlet 101 is lower. When the height of the ribs 303 provided on the transverse air guide plates 302 is smaller, the flow rate of the air passing through the transverse air guide plates 302 is greater, and the corresponding indoor air pressure near the air-conditioning outlet 101 is higher. In this way, the pressure difference of the indoor air at different positions near the air-conditioning outlet 101 along the first direction can be greater, thereby making the indoor air at different positions near the air-conditioning outlet 101 can flow naturally from the high-pressure position to the low-pressure position more quickly, the simulated natural wind outlet effect is better, and people have a better experience of blowing air with air conditioning.

[0060] The transverse wind guide plate 302 has two opposite wind guide surfaces, and the ribs 303 are arranged on the two opposite wind guide surfaces of the transverse wind guide plate 302. In this way, the transverse wind guide plate 302 can adjust the speed of the air flow passing through the two wind guide surfaces of the transverse wind guide plate 302. In this way, the pressure difference of the indoor air at different positions near the air-conditioning outlet 101 along the first direction can be greater, thereby allowing the indoor air at different positions near the air-conditioning outlet 101 to flow naturally from the high-pressure position to the low-pressure position more quickly, and the simulated natural wind outlet effect is better, and people have a better experience of blowing air with the air conditioner.

[0061] See also Figure 5 and Figure 6 The mounting frame 301 is provided with a mounting hole 304 corresponding to the transverse air guide plate 302; the transverse air guide plate 302 includes a plate body 305 and a mounting portion 306 provided on the plate body 305, the mounting portion 306 is arranged opposite to the mounting hole 304, the mounting portion 306 includes two elastic arms 308 arranged opposite to each other, and two snap-fitting protrusions 309 arranged on each elastic arm 308, the two snap-fitting protrusions 309 in the mounting portion 306 are arranged back to back, the two elastic arms 308 in the mounting portion 306 are inserted into the corresponding mounting holes 304, and the two snap-fitting protrusions 309 in the mounting portion 306 abut against the mounting frame 301.

[0062] See also Figure 5The lateral air guide plate 302 also includes an inserting column 307 arranged on the plate body 305; the air guide plate component 300 also includes a joystick and a first motor, the first motor is connected to the joystick in a transmission manner, and is used to drive the joystick to move linearly in a direction parallel to the first direction, and the joystick is provided with an inserting hole corresponding to the inserting column 307, and the inserting column 307 is inserted in the inserting hole.

[0063] In the cabinet air-conditioning indoor unit of an embodiment of the present invention, when the first motor is running, the first motor drives the operating rod to move linearly in the first direction, and the operating rod drives the end of the horizontal air guide plate 302 close to the plug-in column to rotate around the end close to the mounting portion 306, thereby adjusting the air outlet direction of the air-conditioning outlet 101.

[0064] In the cabinet-type air-conditioning indoor unit of an embodiment of the present invention, the number of the air guide plate components 300 is two, and the two air guide plate components 300 are located on both sides of the partition 209, and each air guide plate component 300 is located at the second end of the corresponding fan outlet duct 204.
