[0044] The utility model provides an indoor unit of an air conditioner.

[0045] The indoor unit of the air conditioner is the indoor part of the split air conditioner or the indoor terminal model of the central air conditioner. The air conditioner is used to regulate the indoor air, including regulating the temperature, humidity, air quality, humidifying, dehumidifying, introducing fresh air, etc. The air conditioner can be composed of an evaporator, condenser, compressor, throttling device and other necessary components to form a vapor compression refrigeration cycle system, which outputs cold air / hot air through the fan to achieve cooling and heating of the indoor environment.

[0046] The embodiments of the present invention do not impose any limitation on the specific form of the air conditioner indoor unit, and the air conditioner may be various forms of household air conditioners, commercial central air conditioners, etc.

[0047] Specifically, the specific form of the air conditioner indoor unit can be various forms such as wall-mounted, vertical, integrated, and patio types.

[0048] The following will refer to Figures 1 to 3 , taking a vertical air-conditioner indoor unit as an example to introduce the scheme of an embodiment of the utility model.

[0049] Figure 1 is a structural schematic diagram of an air-conditioning indoor unit according to an embodiment of the utility model; Figure 2 is a cross-sectional schematic diagram of an air conditioner indoor unit according to an embodiment of the utility model; Figure 3 yes Figure 2 The diagram shown is a schematic diagram of the air conditioner indoor unit when the guide block 20 is in the air guiding position.

[0050] like Figures 1 to 3As shown, the indoor unit of the air conditioner according to the embodiment of the present invention may generally include a casing 10 and a guide block 20 .

[0051] The housing 10 defines a receiving space for receiving the main components of the indoor unit of the air conditioner, including the fan 30, the indoor heat exchanger 40, the controller, etc. The indoor heat exchanger 40 and the throttling device are connected with the compressor, the outdoor heat exchanger and other refrigeration elements disposed in the outdoor unit of the air conditioner through pipelines to form a vapor compression refrigeration cycle system.

[0052] The compressor is usually a rolling rotor compressor. The throttling device may include a capillary tube and an electronic expansion valve. For a heat pump air conditioner, the vapor compression refrigeration cycle system also includes a four-way valve for switching the air conditioner between a cooling mode and a heating mode.

[0053] For a heat pump air conditioner, in cooling mode, the indoor heat exchanger 40 functions as an evaporator. In heating mode, the indoor heat exchanger 40 functions as a condenser. The housing 10 may be provided with an air inlet 11 for introducing indoor air.

[0054] An air duct 15 is formed inside the housing 10, and the air duct 15 has an air outlet 12 to allow the heat exchange air in the housing 10 to be blown out of the housing 10 through the air outlet 12. Under the action of the fan 30, the indoor air enters the housing 10 through the air inlet 11, and after completing the forced convection heat exchange with the indoor heat exchanger 40, forms a heat exchange airflow, which is guided by the air duct 15 and blown out from the outlet of the air duct 15.

[0055] For a vertical air conditioner indoor unit, the housing 10 is generally in the shape of an upright column, and its cross section may be square, rectangular, cylindrical, elliptical or other shapes. The air inlet 11 is generally arranged at the back of the housing 10. The aforementioned air duct 15 is generally a cross-flow air duct, and the fan is generally a cross-flow fan.

[0056] In some embodiments of the utility model, the fan 30 is a crossflow fan. For a vertical air conditioner indoor unit, the axis of the crossflow fan 30 can be extended in the vertical direction, and the whole is in a vertical column shape. The fan 30 is also equipped with a crossflow air duct. The outlet of the crossflow air duct is connected to or faces the air outlet 12, so as to guide the airflow of the fan 30 to the air outlet 12.

[0057] In other embodiments, the fan 30 may also be a centrifugal fan, an axial flow fan, a laminar flow fan or other types of fans. Of course, different types of fans will also be configured with corresponding types of air ducts, and the embodiment of the utility model does not limit the type of the fan 30.

[0058] like Figure 3As shown, the guide block 20 is disposed at the air outlet 12. The guide block 20 includes a wind shield 21 and a dividing plate 22. The guide surface 211 of the wind shield 21 faces the inside of the air duct 15, and the dividing plate 22 extends from the guide surface 211 toward the inside of the air duct 15. The dividing plate 22 is used to divide the heat exchange airflow into two streams, and the portions of the guide surface 211 located on both sides of the dividing plate 22 guide the two heat exchange airflows toward the two sides of the air outlet 12 respectively.

[0059] The indoor unit of the air conditioner of the embodiment of the utility model has a guide block 20, which includes a windshield 21 and a partition plate 22. The guide surface 211 of the windshield 21 faces the inside of the air duct 15, and the partition plate 22 extends from the guide surface 211 toward the inside of the air duct 15. The partition plate 22 is used to divide the heat exchange airflow into two streams, and the portions of the guide surface 211 located on both sides of the partition plate 22 respectively guide the two heat exchange airflows toward the two sides of the air outlet 12. The partition plate 22 and the windshield 21 cooperate with each other to achieve the division and diversion of the heat exchange airflow, thereby preventing the heat exchange airflow from being blown forward from the air outlet 12 and directly blowing on the human body.

[0060] In addition, the air-conditioning indoor unit of the embodiment of the utility model can not only prevent direct blowing, but also separate the heat exchange airflow into two streams, thereby realizing wide-angle zoned air supply, reducing air supply dead corners, and making the overall cooling and heating of the indoor environment more uniform and rapid.

[0061] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, it is preferred that the wind shield 21 and the partition plate 22 are integrally formed as a whole, so as to facilitate design and processing.

[0062] Of course, in other embodiments of the present invention, the wind shield 21 and the partition plate 22 may be independent components, and the two may be fastened together by various fastening methods such as gluing, screw connection or clamping.

[0063] In some embodiments of the present invention, Figure 2 As shown, the thickness of the dividing plate 22 gradually decreases from the guide surface 211 and in the direction away from the guide surface 211. In this way, the two side surfaces of the dividing plate 22 form a certain acute angle, so that the two airflows divided by the dividing plate 22 hold an acute angle and gradually move away from each other, making the turning of the airflow smoother and reducing the wind loss.

[0064] Further, in some embodiments of the present invention, Figure 2 and Figure 3 As shown, the end t of the dividing plate 22 away from the guide surface 211 is a sharp tip. Of course, due to the influence of processing accuracy, the end t cannot be a sharp tip in a mathematical sense, and a rounded corner or chamfer based on process considerations is allowed.

[0065] In this way, the cross section of the dividing plate 22 is roughly triangular. With this design, when the heat exchange air flows toward the air outlet 12, it will be "split" more smoothly after reaching the tip t of the dividing plate 22 to form two air flows, so that the energy loss and wind force loss of the heat exchange air flow when colliding with the tip are smaller.

[0066] Further, in some embodiments of the present invention, Figure 2 As shown, the width of the bottom edge where the dividing plate 22 meets the guide surface 211 is b, and the distance between the tip of the dividing plate 22 and the guide surface 211 is h, satisfying: 1≤h / b≤1.5, preferably 0.7≤h / b≤1.2, for example 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 0.75, 0.83, 1.01, etc.

[0067] The inventors consider that, as h / b increases, the two sides of the dividing plate 22 become relatively steeper, and the splitting effect on the heat exchange airflow becomes stronger, but each heat exchange airflow has to go through a larger turning angle when flowing from the side of the dividing plate 22 to the guide surface 211, resulting in greater energy loss. As h / b decreases, the two sides of the dividing plate 22 become relatively flatter, and the splitting effect on the heat exchange airflow becomes weaker, but each heat exchange airflow has a smoother turning process when flowing from the side of the dividing plate 22 to the guide surface 211, resulting in less energy loss.

[0068] The above scheme of the embodiment of the utility model can achieve a balance between the splitting effect and the energy loss by optimizing the design of the value of h / b, thereby achieving the best wind guiding effect.

[0069] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, arc transitions can be adopted between both sides of the dividing plate 22 and the guide surface 211 .

[0070] In this way, when each heat exchange airflow flows from the side of the dividing plate 22 to the flow guide surface 211, the turning process is smoother and the energy loss is smaller.

[0071] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the guide block 20 can move in a direction close to or away from the air outlet 12 to have a closed position in which the wind shield plate 21 closes the air outlet 12, such as Figure 2 , and the wind shield 21 is located outside the air outlet 12 and the end of the guide block 20 is located at the wind guiding position inside the air duct 15, such as Figure 3 .

[0072] In this way, the guide block 20 has the function of closing the air outlet 12. For example, when the air conditioner indoor unit is in the off state, the guide block 20 can be moved to Figure 2 The closed position shown in the figure prevents dust and impurities in the outside air from entering the interior of the housing 10. When the air conditioner indoor unit is turned on, the guide block 20 is moved to the closed position. Figure 3 Air guide position shown.

[0073] In addition, it is understood that the air volume can also be adjusted by adjusting the distance between the wind shield 21 and the air outlet 12. Specifically, when the distance between the wind shield 21 and the air outlet 12 is increased, the air volume increases. When the distance between the wind shield 21 and the air outlet 12 is decreased, the air volume decreases.

[0074] In some embodiments of the present invention, the air conditioner indoor unit further comprises a driving mechanism, which is used to drive the guide block 20 to move.

[0075] Specifically, the driving mechanism may include a motor and a gear rack mechanism. The gear rack mechanism includes a gear and a rack. The motor is used to drive the gear to rotate, and the rack is installed on the housing 10 in a translational manner, meshed with the gear, and connected to the guide block 20. When the motor is running, it drives the gear to rotate, and the gear drives the rack to translate, so as to drive the guide block 20 to translate.

[0076] In addition, the driving mechanism may also include a linear motor, which drives the guide block 20 to translate. Alternatively, the driving mechanism may also include a rotary motor and other commonly used motion mechanisms for converting the rotation of a motor into translation.

[0077] In some embodiments of the present invention, the air conditioner indoor unit further includes a cross-flow fan 30 , which is disposed at the entrance of the air duct 15 to force the heat exchange air flow to enter the air duct 15 .

[0078] In order to cooperate with the crossflow fan 30, the air duct 15 is a crossflow air duct. The air duct 15 includes a first diffuser section, a second diffuser section and a third diffuser section from upstream to downstream.

[0079] like Figure 2 As shown, the walls constituting the air duct 15 include a first air duct wall 151 and a second air duct wall 152. The A1C1 section of the first air duct wall 151 and the A2C2 section of the second air duct wall 152 constitute a first diffuser section. The C1D1 section of the first air duct wall 151 and the C2D2 section of the second air duct wall 152 constitute a second diffuser section. The D1E1 section of the first air duct wall 151 and the D2E2 section of the second air duct wall 152 constitute a third diffuser section.

[0080] like Figure 3As shown, the crossflow fan 30 is arranged in the first diffuser section. The second diffuser section bends and extends from the outlet of the first diffuser section in a first direction. The third diffuser section bends and extends from the outlet of the second diffuser section in a second direction, and the second direction is opposite to the first direction. The outlet of the third diffuser section constitutes the air outlet 12. For example, in Figure 2 In the illustrated orientation of the illustrated embodiment, the first direction is the right side and the second direction is the left side.

[0081] The above-mentioned solution of the embodiment of the utility model is designed in this way to improve the pressure diffusion performance of the air duct 15 and reduce wind loss.

[0082] In some embodiments of the present invention, Figure 3 As shown, the two air duct walls D1E1 and D2E2 of the air duct constituting the third diffuser section can be respectively parallel to the two side surfaces tn and tm of the opposite dividing plate 22. With such a design, the shapes of the airflow channel between the D1E1 section and the side surface tn and the airflow channel between the D2E2 section and the side surface tm can be made more symmetrical, so that the heat exchange airflow flows more smoothly in the two airflow channels.

[0083] In some embodiments of the present invention, please refer to Figure 3 As shown, the third diffuser section is gradually expanded from the inlet to the outlet, or is called a trumpet shape. In other words, the distance between D2 and D1 is smaller than the distance between E2 and E1.

[0084] Due to the provision of the wind shield 21, the air outlet cross section of the air duct 15 adjacent to the air outlet 12 becomes smaller, which may affect the smoothness of the air outlet. To this end, the embodiment of the utility model specifically makes the third diffuser section gradually expand from the inlet to the outlet, so that the ventilation cross section of the air duct 15 adjacent to the air outlet 12 is appropriately increased to make the air outlet smoother.

[0085] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the air conditioner indoor unit further includes two air guide devices 51, 52, which are respectively arranged on both sides of the dividing plate 22 to guide the wind direction of the heat exchange airflow.

[0086] Specifically, each air guide device 51, 52 can be an air guide plate, a swing blade group, or other commonly used forms in existing air conditioners, which will not be described in detail here.

[0087] In some embodiments of the present invention, Figures 1 to 3 As shown, the air-conditioning indoor unit is a vertical air-conditioning indoor unit.

[0088] For a vertical air conditioner indoor unit, the housing 10 is a vertically extending column, and the air outlet 12 can be arranged at the front side of the housing 10, preferably in the shape of a vertical strip with its length direction extending in the vertical direction. The axis of the crossflow fan 30 extends in the vertical direction. The wind shield 21 and the dividing plate 22 of the guide block 20 are both vertical strips with their length direction extending in the vertical direction.

[0089] Due to the provision of the guide block 20, the heat exchange air flow flowing out of the air outlet 12 will not be blown forward, but will be blown out in lateral directions from both lateral sides of the wind shield 21, and will not directly blow on the human body in front of the air conditioner indoor unit, thereby achieving the effect of avoiding people with cold air or hot air.

[0090] In addition, in some other embodiments of the present invention, the air-conditioning indoor unit may also be a wall-mounted air-conditioning indoor unit.

[0091] For a wall-mounted air conditioner indoor unit, the housing 10 is a horizontal column extending horizontally. The air outlet 12 can be arranged at the lower front part of the housing 10 and open to the front and bottom. The air outlet 12 is preferably a horizontal strip with a length direction along the horizontal direction. The wind shield 21 and the dividing plate 22 of the guide block 20 are both horizontal strips with a length direction extending horizontally.

[0092] Due to the provision of the guide block 20, the heat exchange air flow flowing out of the air outlet 12 will not be blown forward, but will be blown out in the lateral direction from the upper and lower sides of the wind shield 21 respectively, and will not directly blow on the human body in front of the air conditioner indoor unit, thereby achieving the effect of keeping cold air or hot air away from people.
