[0044] Figure 1 is a schematic diagram of an air conditioner indoor unit 20 according to an embodiment of the utility model; Figure 2 It is a schematic exploded view of the first air guide plate 32 of the air conditioner indoor unit 20 according to an embodiment of the utility model.

[0045] This embodiment provides an air conditioner indoor unit 20, referring to Figure 1As shown, the air conditioner indoor unit 20 includes: a housing 22 , a front panel 24 and a first air guide plate 32 .

[0046] The front panel 24 is disposed on the front side of the housing 22 ; an air outlet is formed at the lower portion of the front panel 24 .

[0047] refer to Figure 2 As shown, the first air guide plate 32 includes a main board 322 , a light-transmitting plate 326 and a light-emitting module 324 .

[0048] The light-emitting module 324 is disposed in the main board 322 ; the light-transmitting plate 326 is made of a light-transmitting material and is disposed on the main board 322 , so as to allow the light emitted by the light-emitting module 324 to pass through the light-transmitting plate 326 to provide lighting.

[0049] The light emitting module 324 can emit light according to preset conditions, thereby improving the user's interactive experience when using the air conditioner 10. For example, the light emitting module 324 can provide lighting in the form of a breathing light.

[0050] In some optional embodiments, a temperature sensor can also be set on the air conditioner indoor unit 20 to detect the ambient temperature. The light-emitting module 324 can provide lighting according to the temperature difference between the detected ambient temperature and the preset temperature of the air conditioner indoor unit 20. For example, the greater the temperature difference, the higher the lighting brightness of the light-emitting module 324.

[0051] In addition to the above-mentioned exemplary embodiments, the light emitting module 324 may also, but is not limited to, provide lighting when the air conditioner indoor unit 20 is in a certain working mode, such as lighting in cooling, heating or dehumidification modes, or provide lighting according to certain parameters detected by the air conditioner indoor unit 20, such as lighting according to the concentration of pollutants in the ambient air, etc. The light emitting module 324 may also provide lighting of different colors or effects in different working modes.

[0052] The power line of the light emitting module 324 can be led out from the lateral ends of the first air guide plate 32 and introduced into the housing 22 of the air conditioner indoor unit 20. The power line of the light emitting module 324 is preferably led out along the rotation axis where the first air guide plate 32 is connected to the front panel 24 or the housing 22 to prevent the rotation of the first air guide plate 32 from damaging the power line of the light emitting module 324 and completely hide the power line of the light emitting module 324 in appearance.

[0053] The light-transmitting plate 326 can be made of various light-transmitting materials including PC (polycarbonate), PMMA (acrylic, organic glass), glass, etc., which are not limited here. The light-transmitting plate 326 can be integrally formed with the light-emitting module 324 or the light-transmitting plate 326 can be installed and fixed on the surface of the light-emitting module 324.

[0054] In some optional embodiments, the front panel 24 is detachably disposed on the front side of the housing 22, and the first air guide plate 32 is detachably disposed on the housing 22, so as to facilitate the maintenance and cleaning of the air conditioner indoor unit 20. However, it is understood that the first air guide plate 32 may also be detachably disposed on the front panel 24, so as to facilitate opening the air outlet while removing the front panel 24.

[0055] Figure 3 is a schematic cross-sectional view of an air conditioner indoor unit 20 according to an embodiment of the utility model; Figure 4 yes Figure 3 The diagram is a partial enlarged schematic diagram of part A of the indoor unit 20 of the air conditioner.

[0056] refer to Figure 3 and Figure 4 As shown, in some optional embodiments, the first air guide plate 32 has a fixed end close to the upper side of the air outlet and rotatably connected to the shell 22 or the front panel 24, and a rotating end away from the fixed end.

[0057] Furthermore, the surface of the first air guide plate 32 is bent toward the air outlet at the rotating end.

[0058] The air conditioner indoor unit 20 of this embodiment can be an embedded air conditioner indoor unit 20, that is, the air conditioner indoor unit 20 is embedded in the cabinet. Different from the traditional wall-mounted air conditioner indoor unit 20, the embedded air conditioner indoor unit 20 is embedded in the cabinet, so that the air conditioner indoor unit 20 is hidden in appearance, making the home layout more beautiful.

[0059] refer to Figure 3 As shown, in order to adapt to the opening of the cabinet, the air conditioner indoor unit 20 of this embodiment is provided with an air inlet on the upper part of the front panel 24, that is, the front panel 24 is provided with an air inlet and an air outlet at the same time, that is, the air inlet and outlet of the air conditioner indoor unit 20 are located on the same side and correspond to the opening position of the cabinet, so that the air conditioner indoor unit 20 can take in and out air from the front at the same time.

[0060] Figure 3 The diagram shows a position of the first air guide plate 32 when it is in the open state. The first air guide plate 32 of this embodiment is turned upward around the rotation axis of its fixed end, and uses its own plate body to separate the air inlet from the air outlet. Therefore, when the first air guide plate 32 of this embodiment is opened, it can not only guide the outlet air flow by adjusting the rotation height and change the outlet distance, but also separate the air inlet and outlet on its upper and lower sides, so as to prevent the air inlet from directly sucking the heat exchange air flow blown out from the air outlet back into the air conditioner indoor unit 20, thereby optimizing the air inlet and outlet effects of the air conditioner indoor unit 20 and improving the heat exchange efficiency and air supply effect.

[0061] Figure 4The arrows indicate the direction of the airflow at the air outlet guided by the first air guide plate 32. The first air guide plate 32 of this embodiment is bent toward the air outlet at the rotation end away from the rotation axis, so that the surface forms a concave arc surface. When the first air guide plate 32 is opened and the air conditioner indoor unit 20 is discharging air, the airflow direction at the air outlet is guided to tilt downward along the arc surface.

[0062] Since the air outlet of the embedded air conditioner indoor unit 20 is located at the front side thereof, the shape of the first air guide plate 32 of the present embodiment can ensure that the air flow can be blown obliquely downward when the opening of the air outlet is large, so as to avoid the situation where the air supply height of the air conditioner indoor unit 20 is too high and cannot meet the direct blowing requirements of some users. In addition, the air flow blown from the air outlet tends to flow away from the air inlet side due to the guidance of the first air guide plate 32, so it also has a certain effect on preventing the air flow blown from the air outlet from being directly sucked into the air inlet again.

[0063] refer to Figure 4 As shown, in some optional embodiments, the main board 322 has a windward surface facing the air outlet and forming a bend toward the air outlet at the rotating end of the first air guide plate 32, and a leeward surface away from the air outlet and being a straight surface.

[0064] The main board 322 forms the windward surface and / or leeward surface of the first air guide plate 32. In this embodiment, the windward surface and leeward surface of the first air guide plate 32 are formed on the main board 322 at the same time, and a receiving cavity for arranging the light emitting module 324 is formed between the windward surface and the leeward surface at the rotating end of the main board 322, and the light-transmitting plate 326 is arranged at the opening of the receiving cavity.

[0065] The light-transmitting plate 326 of the present embodiment is located at the rotating end of the first air guide plate 32, so the first air guide plate 32 only emits light at the rotating end of the first air guide plate 32, and the light-emitting area is in the shape of a horizontal strip in appearance, thus having a more simple and high-end feel.

[0066] In other optional implementations, for example Figure 2 In the illustrated embodiment, the light-transmitting plate 326 forms the entire leeward side of the first air guide plate 32 , so the entire leeward side of the first air guide plate 32 emits light and can also provide a lighting effect when the first air guide plate 32 is in a closed state.

[0067] The light-transmitting plate 326 may also form the entire windward surface of the first air guide plate 32 , so that the first air guide plate 32 can provide lighting in the direction of the air outlet.

[0068] In order to further enrich the function of the first air guide plate 32 and solve the condensation problem of the air guide plate of the air conditioner indoor unit 20 at the same time, in some optional embodiments, the light emitting module 324 is a heating light strip and is used to heat the main board 322 and the light-transmitting plate 326 when providing lighting.

[0069] The reason why condensation is easily formed at the air guide plate of the indoor unit 20 of the air conditioner is that the air guide plate has a low temperature under the influence of the heat exchange airflow. When it contacts the ambient air with a higher temperature, it is easy to cause the moisture in the ambient air to condense on the air guide plate and form condensation. By heating the first air guide plate 32 to reduce the temperature difference between the first air guide plate 32 and the ambient air, when the ambient air contacts the first air guide plate 32, it is difficult for the moisture in the ambient air to form condensation on the surface of the first air guide plate 32, thereby solving the condensation problem of the air guide plate of the indoor unit 20 of the air conditioner.

[0070] Including Figure 3 and Figure 4 In some embodiments, in order to improve the guiding effect of the outlet airflow, the surface of the first air guide plate 32 is bent at the rotating end toward the air outlet, and the first air guide plate 32 is more directly blown by the heat exchange airflow at the bent position than at other positions, so the temperature is lower. In this embodiment, a heating light strip is arranged in the accommodation cavity formed by the bend, so that this position of the first air guide plate 32 can be heated in a targeted manner, thereby effectively reducing the temperature difference between the temperature of the first air guide plate 32 at this position and the ambient air, and avoiding the condensation problem.

[0071] The heating light bar can be an LED light bar or other heating light bar that has a heating effect while providing lighting.

[0072] In the embodiment where the light emitting module 324 is a heating light strip, since the light emitting module 324 provides lighting and heats the first air guide plate 32 simultaneously, the light emitting module 324 can also provide lighting to prompt the user that the anti-condensation function of the air conditioner indoor unit 20 has been activated.

[0073] In some optional embodiments, the first air guide plate 32 may further include a water immersion sensor for detecting whether condensation is generated on the surface of the first air guide plate 32. When the water immersion sensor detects that condensation is generated on the surface of the first air guide plate 32, a signal is sent to start the light emitting module 324, so that the first air guide plate 32 emits a prompt lighting and is heated to remove the condensation.

[0074] The water immersion sensor can be set on the surface of the first air guide plate 32, or can be set in the main board 322 of the first air guide plate 32, by setting water-permeable holes or water-permeable materials on the surface of the main board 322 or the transparent plate 326 to detect whether condensation is generated on the surface of the first air guide plate 32.

[0075] The air conditioner indoor unit 20 of this embodiment can be an embedded air conditioner indoor unit 20, that is, the air conditioner indoor unit 20 is embedded in the cabinet. Different from the traditional wall-mounted air conditioner indoor unit 20, the embedded air conditioner indoor unit 20 is embedded in the cabinet, so that the air conditioner indoor unit 20 is hidden in appearance, making the home layout more beautiful.

[0076] refer to Figure 3 As shown, in order to adapt to the opening of the cabinet, the air conditioner indoor unit 20 of this embodiment is provided with an air inlet on the upper part of the front panel 24, that is, the front panel 24 is provided with an air inlet and an air outlet at the same time, that is, the air inlet and outlet of the air conditioner indoor unit 20 are located on the same side and correspond to the opening position of the cabinet, so that the air conditioner indoor unit 20 can take in and out air from the front at the same time.

[0077] In some optional embodiments, the front panel 24 forms a plurality of transversely extending air inlet grilles 25 at the air inlet; and each air inlet grille 25 is inclined downward toward the air conditioner indoor unit 20, thereby guiding the airflow to enter the air conditioner indoor unit 20 from the air inlet in a downward inclined direction.

[0078] Figure 3 Arrows are also used to indicate the direction of air flow at the air inlet. Figure 1 and Figure 3 As shown, the front panel 24 of this embodiment forms a plurality of transversely extending air inlet grilles 25 at the air inlet, and the air inlet grilles 25 are arranged in parallel in the longitudinal direction, so that an air inlet gap extending obliquely downward toward the interior of the air conditioner indoor unit 20 is formed between two adjacent air inlet grilles 25 in the longitudinal direction, and the air flow enters the air conditioner indoor unit 20 from the air inlet in an oblique downward direction.

[0079] The air inlet grille 25 at the air inlet can be either a continuous line or multiple intervals in the horizontal direction.

[0080] As Figure 3 As indicated by the middle arrow, the air inlet grille 25 of the present embodiment guides the airflow at the air inlet to enter the air inlet obliquely downward from the upper side, thereby preventing the airflow at the air inlet from convection with the air flow at the air outlet and the airflow blown out of the air outlet from being directly sucked into the air inlet again.

[0081] In some optional embodiments, the air inlet and the air outlet of the front panel 24 are spaced apart in height, so that there is a certain distance between the lower end of the air inlet and the air outlet and the first air guide plate 32 when in the open state, thereby further separating the air inlet and the air outlet, preventing the airflow blown out of the air outlet from being directly sucked into the air inlet again, and reducing the convection between the airflow at the air inlet and the air outlet.

[0082] The reason why condensation is easily formed at the air guide plate of the indoor unit 20 of the air conditioner is that the air guide plate has a lower temperature under the influence of the heat exchange airflow. When it contacts the ambient air with a higher temperature, it is easy to cause the moisture in the ambient air to condense on the air guide plate and form condensation. When the airflow at the air inlet forms convection with the airflow at the air outlet, the upper surface of the first air guide plate 32 in the open state will contact more moisture in the ambient air with the airflow at the air inlet and condensation is more likely to occur.

[0083] Therefore, the utility model sets the rotating end of the first air guide plate 32 to be bent toward the air outlet, each air inlet grille 25 is tilted downward toward the air conditioner indoor unit 20, or the air inlet and the air outlet of the front panel 24 are spaced apart in height, so that the airflows at the air inlet and the air outlet are separated in the flow direction, thereby reducing the convection between the airflow at the air inlet and the air outlet, so as to reduce or even avoid the formation of condensation on the surface of the first air guide plate 32.

[0084] In some optional embodiments, the air conditioner indoor unit 20 can simultaneously set the rotating end of the first air guide plate 32 to be bent toward the air outlet, each air inlet grille 25 to be downwardly inclined toward the air conditioner indoor unit 20, and the air inlet and air outlet of the front panel 24 to be spaced in height, so as to maximize the anti-condensation effect of the air guide plate of the air conditioner indoor unit 20.

[0085] In some optional implementations, the air conditioner indoor unit 20 further includes: an air supply fan 26 , a heat exchanger 28 , and an air inlet baffle 23 .

[0086] The air supply fan 26 is disposed in the housing 22 to facilitate the formation of an air flow that enters the air conditioner indoor unit 20 from the air inlet and is blown out from the air outlet.

[0087] The heat exchanger 28 is disposed in the housing 22 and is located between the air inlet and the air supply fan 26 for exchanging heat with the air flow entering the indoor unit 20 of the air conditioner from the air inlet.

[0088] The air inlet baffle 23 is horizontally arranged in the housing 22, with one end close to the air inlet and the other end close to the heat exchanger 28, so as to separate the air flow entering the air conditioner indoor unit 20 from the air inlet into two parts, upper and lower parts.

[0089] refer to Figure 3 As shown, in order to improve the heat exchange efficiency, the air conditioner indoor unit 20 of this embodiment has a heat exchanger 28 arranged on the upper peripheral side of the air supply fan 26, wherein part of the heat exchanger 28 is close to and faces the air inlet of the air conditioner indoor unit 20, while another part of the heat exchanger 28 is away from the air outlet due to being bent backward and downward.

[0090] In order to prevent the incoming air flow from only passing through the front half of the heat exchanger 28 near the air inlet, causing the rear half of the heat exchanger 28 to not participate in or participate less in heat exchange, an air inlet baffle 23 is particularly arranged in the shell 22, with one end of the air inlet baffle 23 close to the air inlet and the other end close to the heat exchanger 28, thereby dividing the airflow entering the air conditioner indoor unit 20 from the air inlet into two parts, an upper part and a lower part.

[0091] The air conditioner indoor unit 20 of this embodiment utilizes the spacing of the air inlet baffle 23 to allow the air flow entering the air conditioner indoor unit 20 from the lower air inlet to pass through the front half heat exchanger 28, while also ensuring that the air flow entering the air conditioner indoor unit 20 from the upper air inlet can flow to and pass through the rear half heat exchanger 28, thereby making full use of the heat exchanger 28 and avoiding the accumulation of cold energy.

[0092] In this embodiment, a gap is formed between the upper end of the heat exchanger 28 and the upper part of the shell 22 to allow air flow to pass through, and the end of the air inlet baffle 23 can be close to the upper end of the heat exchanger 28, thereby dividing the heat exchanger 28 into two parts, front and rear, and ensuring that the air flow entering from the air inlet of the upper half is guided to the rear half of the heat exchanger 28.

[0093] In the embodiment where the front panel 24 forms an air inlet grille 25 at the air inlet, an end of the air inlet partition plate 23 may abut against an air inlet grille 25 .

[0094] In some embodiments of the present application, the air inlet baffle 23 may not be horizontally arranged in the housing 22, that is, it may be inclined or bent, and the airflow entering the air conditioner indoor unit 20 from the air inlet is also divided into upper and lower parts. However, the above embodiment may affect the normal flow of the airflow and cause the air intake efficiency of the air conditioner indoor unit 20 to decrease, and therefore it is generally not the most preferred embodiment.

[0095] In some optional embodiments, the heat exchanger 28 may also be Figure 3 The illustrated embodiment is arranged on the upper peripheral side of the air supply fan 26, for example, it can be arranged longitudinally or in other ways in the shell 22, and the air inlet baffle 23 can also be correspondingly arranged with its end located in the middle of the height of the heat exchanger 28, thereby dividing the heat exchanger 28 into two upper and lower parts opposite to the air inlet.

[0096] In some optional implementations, the air conditioner indoor unit 20 further includes: an air supply duct 30 and a second air guide plate 34 .

[0097] The air supply duct 30 is disposed in the housing 22 and one end of the air supply duct is connected to the air outlet.

[0098] The second air guide plate 34 is disposed in the air supply duct 30 and has a rotation axis close to the lower surface of the air supply duct 30 and extending laterally, and is used to guide the air outlet direction of the air conditioner indoor unit 20.

[0099] refer to Figure 3 As shown, the air supply duct 30 of this embodiment is connected to the air outlet at one end and to the air supply fan 26 at the other end, so as to guide the air flow formed by the air supply fan 26 to blow toward the air outlet. The first air guide plate 32 is arranged at the air outlet, and the two ends of its rotation axis are connected to the two lateral walls of the air supply duct 30. The second air guide plate 34 is arranged close to the lower surface of the air supply duct 30, and the two ends of its rotation axis can also be connected to the two lateral walls of the air supply duct 30.

[0100] The second air guide plate 34 can swing upward from a position close to the lower surface of the air supply duct 30, so as to adjust the air outlet height of the air conditioner indoor unit 20. When the swing height of the second air guide plate 34 is high, the size of the air outlet can also be reduced, so as to change the distance of the air outlet and the perceived wind speed in accordance with the speed change of the air supply fan 26. For example, when the speed of the air supply fan 26 remains unchanged, when the swing height of the second air guide plate 34 is high and the air outlet is reduced, the actual air outlet speed of the air conditioner indoor unit 20 becomes faster due to the reduction of the air outlet. When the speed of the air supply fan 26 decreases, the actual air outlet speed of the air conditioner indoor unit 20 can be maintained stable by reducing the size of the air outlet by swinging the second air guide plate 34, so as to reduce the air supply volume of the air conditioner indoor unit 20 when the perceived wind speed remains basically unchanged, so as to adjust the ambient temperature.

[0101] In some optional implementations, the air conditioner indoor unit 20 further includes: a third air guide plate group.

[0102] The third air guide plate group is arranged in the air supply duct 30 and includes a plurality of third air guide plates 36 distributed in the transverse direction; each third air guide plate 36 has a longitudinally extending rotation axis for guiding the air outlet direction of the air conditioner indoor unit 20.

[0103] Figure 3 Only one third air guide plate 36 in the third air guide plate group can be seen, but it can be understood that multiple third air guide plates 36 of this embodiment are arranged side by side in the air supply duct 30. In some optional embodiments, multiple third air guide plates 36 in the third air guide plate group can be synchronously controlled to rotate and adjust the lateral air outlet direction of the air conditioner indoor unit 20.

[0104] exist Figure 3 In the illustrated embodiment, the third air guide plate group is disposed on the lower surface of the air supply duct 30 , while in other optional implementations, the third air guide plate group may also be disposed on the upper surface of the air supply duct 30 .
