Abstract
Description
Technical Field
[0001] The utility model relates to, but is not limited to, the technical field of household appliances, and more specifically, to an air conditioner and an inner air guide plate and an indoor unit thereof. Background Art
[0002] In related art, some air conditioners have inner and outer air guides. The outer air guide serves to guide air and also controls the opening and closing of the air outlet. The inner air guide also serves to guide air and is evenly distributed with ventilation holes to disperse the wind, achieving a windless effect. However, in heating mode, hot air can easily flow through the ventilation holes in the inner air guide and outward, resulting in a small amount of hot air flowing downward, affecting the heating effect. Utility Model Content
[0003] The technical problem to be solved by the present application is to provide an air conditioner and its inner air guide plate and indoor unit, which are conducive to improving the heating effect of the air conditioner.
[0004] An embodiment of the present application provides an inner air guide plate, which is applied to an air conditioner. The inner air guide plate includes a ventilation part and a compressed air part connected to each other. The ventilation part is provided with ventilation holes. The compressed air part is located on one side in the width direction of the ventilation part and is arranged to be located on the upper side of the ventilation part when the air conditioner is in heating mode, so as to limit the airflow passing through the compressed air part and guide the airflow to flow downward.
[0005] Thus, in heating mode, when the airflow from the upper portion of the air outlet flows toward the inner air guide plate, it cannot pass horizontally through the compressed air section and must change direction to flow downward along the compressed air section, thereby increasing the amount of hot air flowing downward. Therefore, the compressed air section can function as a heating compressed air source, which helps improve comfort and heating effects in heating mode. The ventilation section, on the other hand, is equipped with ventilation holes that disperse the wind, achieving a windless effect.

[0029] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.
[0030] The embodiment of the present application provides an air conditioner, an inner air guide plate 1 thereof, and an indoor unit.
[0031] The air conditioner can be a split type air conditioner, which includes an indoor unit and an outdoor unit, and the indoor unit is connected to the outdoor unit. The indoor unit can be but is not limited to a wall-mounted indoor unit, such as Figures 1 to 5 Alternatively, the air conditioner may be an integrated air conditioner.
[0032] Accordingly, the inner air guide plate 1 can be installed at the air outlet 31 of the indoor unit of a split-type air conditioner, or can be installed at the air outlet 31 of an integrated-type air conditioner.
[0033] The following explanation is given using a split air conditioner as an example.
[0034] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the indoor unit of the split-type air conditioner includes: a housing 3, an outer air guide plate 2 and an inner air guide plate 1.
[0035] The housing 3 is provided with an air outlet 31. The housing 3 may include a face frame, a chassis, and a panel. The face frame is connected to the chassis, with its front end open. The panel cover is located at the front opening of the face frame and forms the air outlet 31 between the panel cover and the bottom of the face frame. The indoor unit also includes an indoor heat exchanger 5 and a fan 4, disposed within the housing 3. The fan 4 rotates, drawing indoor air into the housing 3. After exchanging heat with the indoor heat exchanger 5, the air is discharged through the air outlet 31.
[0036] The outer air guide plate 2 is rotatably arranged at the air outlet 31, and is arranged to be able to open the air outlet 31 in the open position (such as Figure 2 and Figure 3 ) and the closed position of the air outlet 31 (as shown) Figure 1 When the outer air guide plate 2 is in the open position, the outer air guide plate 2 can be located at the lower side of the air outlet 31 to ensure that the air outlet 31 is fully open.
[0037] The inner air guide plate 1 is rotatably arranged at the air outlet 31 and is arranged to be able to Figure 1 and Figure 2 As shown) and the second wind guide position (as shown Figure 3 and Figure 5 As shown in FIG, the inner air guide plate 1 rotates between the first air guide position and the second air guide position, and the inner air guide plate 1 is configured to rotate toward the outside of the housing 3. In the first air guide position, the inner air guide plate 1 can be located inside the housing 3, and the inner air guide plate 1 is generally in a horizontal state (can be close to a horizontal direction), as shown in FIG. Figure 2 As shown, the air flow is guided to be transported to a distant place, which is conducive to long-distance air supply. In the second air guide position, the inner air guide plate 1 can be partially located outside the air outlet 31, and the inner air guide plate 1 can be roughly in a vertical state (can be close to the vertical direction), as shown in FIG. Figure 3 As shown, the airflow is guided downward, which is conducive to vertical air supply.
[0038] Based on the air conditioner being in heating mode (such as Figure 3 As shown): the outer air guide plate 2 is in the open position, the inner air guide plate 1 is in the second air guide position, and the inner air guide plate 1 is located on the upper side of the outer air guide plate 2.
[0039] Among them, such as Figure 4 As shown, the inner air guide plate 1 includes a ventilation portion 11 and a compressed air portion 12 connected to each other. The ventilation portion 11 is provided with a ventilation hole 111. The compressed air portion 12 is located on one side of the width direction of the ventilation portion 11 and is arranged to be located on the upper side of the ventilation portion 11 when the air conditioner is in heating mode, so as to limit the airflow passing through the compressed air portion 12 and guide the airflow to flow downward.
[0040] Thus, in heating mode, when the airflow above the air outlet 31 flows toward the inner air guide plate 1, it cannot pass horizontally through the compressed air portion 12 and can only change direction and flow downward along the compressed air portion 12, thereby increasing the amount of hot air flowing downward. Therefore, the compressed air portion 12 can function as a heating compressed air source, which is beneficial for improving comfort and heating effects in the air conditioning heating mode. The ventilation portion 11 is provided with ventilation holes 111, which can disperse the wind, achieving a windless effect.
[0041] In some exemplary embodiments, Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the rotation axis of the outer air guide plate 2 can be located below the rotation axis of the inner air guide plate 1, so that the inner air guide plate 1 can guide the air in the middle and upper range of the air outlet 31, and the outer air guide plate 2 can guide the air in the middle and lower range of the air outlet 31.
[0042] like Figure 4 As shown, the inner air guide plate 1 can be rotatably connected to the shell 3 through the connecting plate 13, and the connecting plate 13 can be connected to the inner plate surface of the air pressure part 12. The outer air guide plate 2 can be rotatably connected to the shell 3 through the connecting arm 21, as shown. Figure 3 shown.
[0043] Ignoring the thickness of the inner air guide plate 1, the contour line of the inner air guide plate 1 in the width direction can be a straight line, an arc, or a broken line. Ignoring the thickness of the outer air guide plate 2, the contour line of the outer air guide plate 2 in the width direction can be a straight line, an arc, or a broken line.
[0044] In some exemplary embodiments, the outer air guide plate 2 has a third air guide position, which is located between the open position and the closed position. Figure 5 In the third wind guide position, the outer wind guide plate 2 can be roughly in a horizontal state (can be close to the horizontal direction) to guide the airflow to a distance and avoid the airflow directly blowing on the user.
[0045] like Figure 1 As shown, based on the air conditioner being in the off state: the outer air guide plate 2 is in the closed position, and the inner air guide plate 1 is in the first air guiding position.
[0046] like Figure 2 As shown, the air conditioner is in cooling mode: the outer air guide plate 2 is in the open position, and the inner air guide plate 1 is in the first air guide position. This facilitates the rapid downward discharge of some cold air along the outer air guide plate 2, and also facilitates the transmission of some cold air along the inner air guide plate 1 to distant places, thereby improving the comfort of cooling mode.
[0047] like Figure 5As shown, based on the air conditioner being in the no-wind mode: the outer air guide plate 2 is located at the third air guide position, and the inner air guide plate 1 is located at the second air guide position.
[0048] The outer air guide plate 2 may also be provided with ventilation holes 111, such as Figure 3 When the outer air guide plate 2 is in the third air guide position and the inner air guide plate 1 is in the second air guide position, the upper end of the outer air guide plate 2 and the lower end of the inner air guide plate 1 can be substantially flush, so that the airflow output from the air outlet 31 is discharged through the ventilation holes 111 as much as possible, thereby improving the comfort of the no-wind mode.
[0049] In some exemplary embodiments, the air pressure portion 12 is provided with a blind hole 121, such as Figure 4 shown.
[0050] In some embodiments, the blind hole 121 and the ventilation hole 111 have the same cross-sectional shape, such as circular, polygonal, elliptical, etc. The cross-sectional shape refers to the shape of the cross section perpendicular to the depth direction of the blind hole 121 or the ventilation hole 111 .
[0051] In some embodiments, the blind holes 121 and the ventilation holes 111 have the same distribution density. The blind holes 121 and the ventilation holes 111 may also have the same cross-sectional area, where the cross-sectional area refers to the area of the section perpendicular to the depth direction of the blind holes 121 or ventilation holes 111.
[0052] In some embodiments, both sides of the air pressure part 12 are provided with blind holes 121. Figure 4 shown.
[0053] In this way, the inner air guide plate 1 has no obvious distinction between the ventilation part 11 and the air pressure part 12 in appearance, and the overall appearance is relatively regular, which is conducive to improving the aesthetics of the inner air guide plate 1.
[0054] Of course, the cross-sectional shape of the blind holes 121 and the ventilation holes 111 may be different, and the distribution density thereof may be different. Alternatively, the blind holes 121 may be provided on only one side of the plate. Alternatively, the air pressure portion 12 may not be provided with the blind holes 121.
[0055] It is understood that, compared to the prior art inner air guide plate 1 with uniformly distributed ventilation holes 111, in the embodiment of the present application, ventilation holes 111 are partially eliminated from the inner air guide plate 1. To ensure the effect of the windless mode, the distribution density of the ventilation holes 111 and the air outlet direction of the ventilation holes 111 can be adjusted accordingly. For example, the distribution density of the ventilation holes 111 of the inner air guide plate 1 can be appropriately increased, the density of the ventilation holes 111 can be appropriately increased, or the air outlet direction of the multiple ventilation holes 111 can be set to a gradual change.
[0056] In some exemplary embodiments, the ratio of the width of the air pressure portion 12 to the width of the inner air guide plate 1 is in a range of 1 / 4 to 3 / 4. The ratio of the width of the air pressure portion 12 to the width of the inner air guide plate 1 is the ratio of the area of the air pressure portion 12 to the area of the inner air guide plate 1.
[0057] In some embodiments, the ratio of the width of the air pressure portion 12 to the width of the inner air guide plate 1 is 1 / 2.
[0058] It has been verified through experiments that when the ratio of the width of the compressed air portion 12 to the width of the inner air guide plate 1 is within the above range, a better heating compressed air effect can be achieved, and the impact on the no-wind mode is relatively small.
[0059] Of course, the ratio of the width of the air pressure portion 12 to the width of the inner air guide plate 1 is not limited to the above range and can be adjusted as needed.
[0060] The embodiment of the present application also provides an air conditioner, including the indoor unit of any one of the above embodiments or the inner air guide plate 1 of any one of the above embodiments, thus having all the above beneficial effects, which will not be repeated here.
