Technical Field

[0001] The invention relates to the technical field of air conditioning, in particular to a vertical air-conditioning indoor unit. Background Art

[0002] The existing vertical air conditioner indoor unit usually has an air outlet on the front side of the shell, which is mainly used to blow air forward. The air outlet is provided with an air guide device, such as an air guide plate, a vertical swing blade, etc., to guide the air horizontally so that the air flow is blown to a set area such as the front, left front, and right front of the air conditioner.

[0003] In recent years, anti-direct blowing air supply technology has emerged. A hole is opened on the shell of the air conditioner. In the anti-direct blowing mode, the original air outlet is closed, forcing the air flow to blow out through the hole of the shell, achieving a breeze effect and making the human body more comfortable. However, in the anti-direct blowing mode, the air outlet angle range is too small, and basically only the air can be discharged forward. There is no way to use the air guide device to guide the direction of the airflow. Summary of the invention

[0012] At the front wind guide position, the inner side surfaces of the two wind guide plates face each other;

[0013] At the double-sided wind guiding position and the multi-dimensional wind guiding position, outer side surfaces of the two wind guiding plates face each other.

[0014] Optionally, the two wind guide plates are configured such that, at the double-sided wind guide position and the multi-dimensional wind guide position, each plate body is gradually inclined from back to front in a direction away from the lateral center.

[0015] Optionally, the vertical air conditioner indoor unit further includes: at least one baffle plate for adjusting the opening and closing state and the opening area of ​​the air outlet area in the middle of the front cover plate of the air scattering hood; so that the vertical air conditioner indoor unit has:

[0016] The two air guide plates are placed in the front air guide position, and the baffle plate opens the middle air outlet area of ​​the front cover plate, so that the air dispersion cover is in the front air supply mode where the air is discharged forward;

[0017] The two air guide plates are placed in the double-sided air guide position, and the baffle closes the middle air outlet area of ​​the front cover plate, so that the air dispersion cover discharges air to both sides in a double-sided air supply mode; and / or

[0018] The two air guide plates are placed in the multi-dimensional air guide position, and the baffle opens the middle air outlet area of ​​the front cover plate, so that the air dispersion cover simultaneously discharges air forward and to both sides in a multi-dimensional air supply mode.

[0019] Optionally, there are two baffles, and the two baffles can be reciprocated and translated in a lateral direction to be abutted against the inner side of the front cover plate in an open position.

[0020] Optionally, when the baffle closes the middle air outlet area of ​​the front cover plate, the areas of the front cover plate on both lateral sides of the baffle plate have open air outlet areas.

[0021] Optionally, the wind dissipation cover includes a front cover plate arranged upright and two side cover plates extending backwards from two lateral sides of the front cover plate respectively, and the front cover plate and the two side cover plates are both used for discharging air.

[0038] The embodiment of the present invention provides a vertical air conditioner indoor unit, which is the indoor part of a split vertical air conditioner. The air conditioner is used to adjust the indoor air, including adjusting the temperature, humidity, air quality of the air, humidifying, dehumidifying, introducing fresh air, etc.

[0039] like Figures 1 to 6 As shown, the vertical air-conditioning indoor unit according to the embodiment of the present invention may generally include a housing 10 , a wind dissipation cover 20 and two wind guide plates 54 .

[0040] The front wall 13 of the housing 10 is provided with an air outlet 12 for blowing out the airflow inside the housing 10. The front wall 13 is the wall of the housing 10 that is exposed to the outside and faces forward. When the air conditioner is in cooling mode, the airflow from the air outlet 12 is cold air; when the air conditioner is in heating mode, the airflow from the air outlet 12 is hot air. Of course, if the air conditioner has additional regulating functions such as purification and fresh air, the airflow from the air outlet 12 may also include regulated airflows such as purification airflow and fresh air airflow.

[0041] Specifically, Figure 4 As shown, the housing 10 defines a containing space for containing the main components of the vertical air conditioner indoor unit, including the fan 30, the indoor heat exchanger 40, the controller, etc. The rear portion of the housing 10 may be provided with an air inlet 11. The indoor heat exchanger 40, the throttling device, the compressor, the outdoor heat exchanger and other refrigeration elements arranged in the air conditioner outdoor unit are connected through pipelines to form a vapor compression refrigeration cycle system. In the cooling mode, the indoor heat exchanger 40 is an evaporator. In the heating mode, the indoor heat exchanger 40 is a condenser. Under the action of the fan 30, the indoor air enters the interior of the housing 10 through the air inlet 11, and after completing the forced convection heat exchange with the indoor heat exchanger 40, a heat exchange airflow is formed, which is guided by the air duct 15 and flows out from the air outlet 12. The housing 10 can be made into an upright column as a whole, and its cross section can be square, rectangular, cylindrical, elliptical or other shapes. The fan 30 may be a cross-flow fan, the air duct 15 may be a cross-flow air duct, and the outlet of the air duct 15 is connected to the air outlet 12 .

[0042] The wind hood 20 is buckled in front of the front wall 13 of the housing 10 to define an airflow space 205 with the front wall 13. Figure 4 .like Figure 1 As shown, the air hood 20 has a grille outlet area, and the area is defined by a plurality of grille bars to form a plurality of long strip or block-shaped grille holes for air outlet. Alternatively, in some alternative embodiments, the air hood 20 may have a micropore outlet area, that is, the area of ​​the air hood 20 is provided with a plurality of micropores for air outlet. Alternatively, the air hood 20 has both a grille outlet area and a micropore outlet area. The air hood 20 and the housing 10 may be fastened together by a snap connection or a screw connection. Alternatively, the air hood 20 and the housing 10 may be an integrally formed integral part.

[0043] like Figures 1 to 4 As shown, the wind dispersing cover 20 may include a front cover plate 21 arranged vertically and two side cover plates 22, 23 extending backward from the lateral sides of the front cover plate 21, respectively. The front cover plate 21 and the two side cover plates 22, 23 are all used for discharging air. The front cover plate 21 has an air outlet area 211, the side cover plate 22 on the left side has an air outlet area 222, and the side cover plate 23 on the right side has an air outlet area 233.

[0044] The vertical air conditioner indoor unit is configured so that the airflow from the air outlet 12 first enters the airflow space 205, and then penetrates the air hood 20 to blow forward and / or to the lateral sides. The direction referred to by "lateral" in this article has been marked in the figure, that is, the left and right direction. In this way, the airflow from the air outlet 12 will not blow directly to the indoor environment, but first enters the airflow space 205 between the air hood 20 and the outer wall of the shell 10, and then penetrates different areas of the air hood 20 to blow in different directions, so that the air outlet angle range is larger than the air outlet angle range of the original air outlet 12, so that the vertical air conditioner indoor unit can better take into account the anti-direct blowing function and the air outlet angle range, and the design is very clever.

[0045] The two air guide plates 54 are arranged at two lateral sides (left and right) of the air outlet 12 to guide the air flow forward. Figure 4 In the front wind guide position, the two wind guide plates 54 are respectively blocked on the left and right sides of the air outlet 12, so that the air flow cannot flow horizontally in large quantities or completely, and can only flow forward. In addition, the two wind guide plates 54 also have a double-sided wind guide position that is horizontally attached to the front central area of ​​the air outlet 12 to guide the air flow to the horizontal sides, such as Figure 5 In the double-sided wind guide position, since the two wind guide plates 54 are very close and located in the center in front of the air outlet 12, the forward path of the outlet air flow will be blocked to guide the outlet air flow to flow toward the lateral sides.

[0046] When the two air guide plates 54 are in the aforementioned front air guide position, the air is mainly discharged from the front air outlet area 211 of the air scattering cover 20, so that the air flow flows out forward, and this air supply mode of the vertical air conditioner indoor unit can be called the front air supply mode. When the two air guide plates 54 are in the aforementioned double-sided air guide position, the air is mainly discharged from the air outlet areas 222 and 233 on the lateral sides of the air scattering cover 20, and the main body or all of the air flow flows out in two lateral directions (left and right), and this air supply mode of the vertical air conditioner indoor unit can be called the double-sided air supply mode.

[0047] Furthermore, if Figure 6 As shown, the two air guide plates 54 also have multi-dimensional air guide positions arranged transversely in the front central area of ​​the air outlet 12 and spaced apart to guide the outlet air flow to the transverse sides and allow the outlet air interval (mn) to be discharged forward at the same time. So that the air hood 20 discharges air forward and to the transverse sides at the same time. That is, the outlet area 211 of the front cover plate 21, the outlet area 222 of the side cover plate 22, and the outlet area 233 of the side cover plate 23 all discharge air.

[0048] The vertical air conditioner indoor unit of the present invention adjusts the air outlet direction of the air outlet through two air guide plates 54 so as to have multiple air supply modes such as front air supply mode, double-side air supply mode, and multi-dimensional air supply mode, which fully meet various needs of users.

[0049] In some embodiments, Figures 4 to 6 As shown, the two air guide plates 54 can rotate around the vertical axis x3. Each air guide plate 54 is equipped with a motor 90, which is installed in the drive box 16 of the housing 10. The drive box 16 is located directly above the air hood 20. Figure 2 The rotation axis x3 of the two air guide plates 54 is located inside the plate body 540 of the air guide plate 54 and is spaced apart from the inner side surface 541 of the plate body 540. The other side surface of the plate body 540 is the outer side surface 542. In the front air guide position, the inner side surfaces 541 of the two air guide plates 54 face each other. Figure 4 In the double-sided wind guiding position and the multi-dimensional wind guiding position, the outer side surfaces 542 of the two wind guiding plates 54 face each other. Figure 5 and Figure 6 In some alternative embodiments, the two wind guide plates 54 may be switched between the front wind guide position, the double-side wind guide position and the multi-dimensional wind guide position in a translational or planar motion (translation+rotation) manner.

[0050] like Figure 5 and Figure 6 As shown, the two air guide plates 54 can be configured in a double-sided air guide position and a multi-dimensional air guide position, so that each plate body 540 gradually tilts from back to front in a direction away from the lateral center, so as to better guide the airflow toward the lateral sides.

[0051] In some embodiments, Figures 2 to 6 As shown, the vertical air conditioner indoor unit may further include at least one baffle 62. The baffle 62 is used to adjust the opening and closing state and the opening area of ​​the middle air outlet area of ​​the front cover plate 21 of the air hood 20. In this way, the vertical air conditioner indoor unit has one or more of the following air supply modes.

[0052] (1) Front air supply mode. Figure 4 As shown, the two air guide plates 54 are in the front air guide position, and the baffle 62 opens the middle air outlet area of ​​the front cover plate 21 (i.e., the part of the air outlet area of ​​the front cover plate 21 located directly in front of the air outlet 12), so that the air hood 20 discharges air forward.

[0053] (2) Double-sided air supply mode. Figure 5 As shown, the two air guide plates 54 are in the double-sided air guide position, and the baffle 62 closes the middle air outlet area of ​​the front cover plate, so that the air dispersion cover 20 discharges air toward both lateral sides.

[0054] (3) Multi-dimensional air supply mode. Figure 6As shown, the two air guide plates 54 are placed in the multi-dimensional air guide position, and the baffle 62 opens the middle air outlet area of ​​the front cover plate 21, so that the air hood 20 discharges air forward and to both sides. That is, the air outlet area 211 of the front cover plate 21 discharges air, and the air outlet area 222 of the side cover plate 22 and the air outlet area 233 of the side cover plate 23 discharge air.

[0055] Furthermore, when the baffle 62 closes the middle air outlet area of ​​the front cover plate 21, it is preferred that the areas of the front cover plate 21 on both sides of the baffle 62 still have open air outlet areas 211. For example, it is preferred that the air outlet area 211 of the front cover plate 21 covers the entire width direction of the front cover plate 21, and the middle part of the air outlet area 211 in the horizontal direction constitutes the aforementioned "middle air outlet area". In this way, in the double-sided air supply mode, although the middle air outlet area (the middle part of the air outlet area 211 in the horizontal direction of the front cover plate 21) is blocked, the left and right parts of the air outlet area 211 of the front cover plate 21 are still open and can be used for air outlet.

[0056] In some embodiments, Figures 4 to 6 As shown, the number of the aforementioned at least one baffle 62 is two, and the two baffles 62 can be reciprocated and translated in the lateral direction to be abutted against the inner side of the front cover plate 21. When the two baffles 62 are laterally separated from each other, so that the right end d of the left baffle 62 and the left end e of the right baffle 62 are spaced apart, the middle air outlet area of ​​the front cover plate 21 is opened. When the right end d of the left baffle 62 and the left end e of the right baffle 62 abut against each other, the middle air outlet area of ​​the front cover plate 21 is closed.

[0057] Each baffle 62 may be provided with a drive mechanism such as a gear rack mechanism to drive it to reciprocate in the lateral direction. Figure 3 As shown, each gear rack mechanism 80 includes a motor 81, a gear 82 and a rack 83. When the motor 81 rotates, the gear 82 is driven to rotate, and when the gear 82 rotates, the rack 83 is driven to translate. The rack 83 is connected to the baffle 62 to drive the baffle 62 to translate.

[0058] In some embodiments, Figure 1-Figure 2 As shown, the portion of the outer wall of the housing 10 where the air outlet 12 is provided is recessed inwardly so that the outer contour of the air hood 20 is smoothly connected with the outer contour of the outer wall of the surrounding housing 10. For example, the outer surface of the air hood 20 is flush with the outer surface of the housing 10 without being seriously protruding or recessed. Figure 1 This makes the air diffuser 20 more integrated with the housing 10 at least in terms of appearance, and does not appear abrupt.

[0059] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
