Description

Technical Field

[0001] The utility model relates to the field of air conditioning, in particular to an indoor unit of an air conditioning. Background Art

[0002] There are two different trends in the current development of air conditioning technology: one is to pursue a stable, clean, non-irritating (neither hot nor cold) artificial environment, because this environment is most conducive to human health; the other is to advocate the appropriate dynamicization of the thermal environment, that is, not completely changing the adaptive relationship between people and the natural environment, and only using simple to complete conscious adjustment methods (such as natural ventilation, artificial isothermal dynamic air supply, non-isothermal dynamic air supply, etc.) to improve the indoor environment when necessary. The blowing method is one of the main factors affecting human thermal comfort. A reasonable blowing method can not only improve people's blowing feeling, but also increase the upper temperature limit of human thermal comfort, reduce air conditioning energy consumption, and achieve energy saving; the traditional mechanical air supply of air conditioning is a continuous steady-state airflow, which is easy to cause a blowing feeling and discomfort, and the transient airflow can significantly improve human comfort; therefore, creating a dynamic and disorderly changing airflow and improving the fatigue of air conditioning blowing has gradually become a common demand. At present, there is no better solution to this problem; solving the obvious blowing feeling and monotonous wind feeling and breaking the traditional mechanical air guide form have become important directions for comfortable air supply of air conditioning.

[0003] There are two main solutions currently available in the industry:

[0004] 1. Motor frequency conversion method (commonly used in academic research): simulate natural wind by controlling the fan speed. However, the speed fluctuation can easily cause the noise to fluctuate, and the low wind speed accounts for a large proportion, resulting in poor heat exchange effect; 2. Multiple wind plate sequential sweeping method (commonly used by Japanese brands): multiple horizontal and vertical wind plates sweep in different orders to simulate natural wind. There is still periodic wind speed, the natural wind feeling is weak, and multiple wind plates sweep across the human body, generating multiple airflows that are perceived at the same time, and the cold feeling is obvious.

[0048] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0049] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0050] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0051] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0052] The air conditioner in this application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0053] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0054] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0055] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0056] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0057] like Figure 1-7As shown, a first aspect of an embodiment of the present application proposes an air-conditioning indoor unit, comprising: a shell 1, an indoor heat exchanger and an air guide plate 2, the shell 1 is provided with an air outlet 11, the indoor heat exchanger is arranged in the shell 1, and is used for heat exchange with indoor air, and the air guide plate 2 is rotatably installed on the air outlet 11, and is used for changing the air outlet angle; wherein, the air guide plate 2 is a double-layer structure, comprising a first plate 21 and a second plate 22 arranged at intervals from top to bottom, and the first plate 21 is provided with a plurality of spoilers 23 at intervals along the length direction, and the spoilers 23 are holes or protrusions. When the spoilers 23 are holes, the spoilers 23 pass through the first plate 21 up and down; when the spoilers 23 are protrusions, the spoilers 23 are arranged on the first plate 21, and are used for breaking up the airflow of the air outlet 11. Preferably, the spoilers 23 are perpendicular to the air outlet direction and are arranged above the first plate 21.

[0058] Based on the above technical scheme, in the air-conditioning indoor unit of the present application, the outer shell 1 serves as a carrier for accommodating the indoor heat exchanger, and an air outlet 11 is arranged on it for air conditioning to discharge air. The indoor heat exchanger can exchange heat with the indoor air, thereby cooling or heating the indoor temperature. The rotating shaft on the air guide plate 2 cooperates with the outer shell 1 to realize rotation, thereby changing the air outlet angle to realize functions such as blowing. The first plate 21 is closer to the air outlet 11 than the second plate 22, corresponding to the air outlet position. Therefore, a spoiler 23 is arranged on the side of the first plate 21 close to the top to effectively break up the airflow, and when the air guide plate 2 rotates to the upper limit position, the first plate 21 is located away from the upper volute tongue, which is conducive to breaking up the airflow and does not affect the wind guiding; if the spoiler 23 is arranged on the second plate 22, when the air guide plate 2 rotates to the upper limit position, one side of the spoiler 23 is located close to the upper volute tongue, and the wind field will not be transmitted to the other side, thereby losing the wind guiding and sweeping functions. When the spoiler 23 is a hole-slot structure, the airflow can be dispersed from the hole-slot gap and partially blown out from between the first plate 21 and the second plate 22, which has the effect of dispersing wind and spoiling flow and improving the ability to prevent direct blowing. When the spoiler 23 is a convex block structure, the airflow hitting the spoiler 23 can also play the role of dispersing wind and spoiling flow and improving the ability to prevent direct blowing. Preferably, the number of rotating shafts on the air guide plate 2 is four, which are respectively located at the two ends and the middle of the length direction of the air guide plate 2, and are symmetrically arranged, taking into account the stability of installation and rotation. In addition, the spoilers 23 are preferably evenly distributed, and the spacing between the spoilers 23 arranged on each part between the rotating shafts is completely consistent, with the purpose of evenly dispersing wind while satisfying the principle of symmetrical, uniform and beautiful appearance.

[0059] In some embodiments of the present application, Figure 1-7As shown, the spacing between the first plate 21 and the second plate 22 is 6mm-12.5mm. The spacing between the first plate 21 and the second plate 22 is 6mm to 12.5mm, which is a more suitable size. If the spacing is too small, when the spoiler 23 is a hole slot, the wind passing through the spoiler 23 is difficult to disperse from between the first plate 21 and the second plate 22, thereby affecting the spoiler effect and the air outlet efficiency; and if the spacing is too large, too much internal space of the air conditioner indoor unit will be occupied, and the air conditioner's ability to prevent direct blowing will be significantly impeded.

[0060] Specifically, Figure 1-7 As shown, the spacing between the first plate 21 and the second plate 22 is 8.5 mm. Through experiments and simulation verification, the performance of the air guide plates 2 of various sizes, such as 12.5 mm, 10.5 mm, 8.5 mm and 6 mm, is verified respectively. Finally, it can be found that reducing the spacing between the first plate 21 and the second plate 22 within a certain range is beneficial to improving the anti-direct blowing capability. Considering the appearance and mold feasibility, 8.5 mm is a more suitable size.

[0061] In some embodiments of the present application, Figure 2-5 As shown, when the spoiler 23 is a hole slot, the spoiler 23 divides the first plate 21 into a plurality of three-pointed star shapes or four-pointed star shapes spaced apart along the length direction of the first plate 21, and the spoilers 23 are arranged in sequence from left to right with a phase difference of 60°. When the spoiler 23 is a hole slot, the air from the air outlet 11 will be dispersed when passing through the hole slot, achieving a natural wind feeling, and in order to further enhance the effect of dispersing the airflow, the present embodiment adopts a method of combining a plurality of spoilers 23 to form a plurality of groups of hole slots. Among them, when the first plate 21 is divided into a three-pointed star shape, the spoiler 23 is a fan-shaped structure with a smooth transition, and the three fan-shaped structures are arranged circumferentially to form a group of holes and slots for breaking up the airflow. When observed from the front, the overall structure is similar to the Mercedes-Benz logo shape, and in order to further enhance the sense of disorder of the air outlet, each adjacent group of holes and slots adopts a 60° phase difference array distribution arrangement, which makes the effect of breaking up the air outlet better; when the first plate 21 is divided into a four-pointed star shape, the spoiler 23 is an arc-shaped long strip structure, and multiple spoilers 23 are arranged at intervals to form a shape similar to the volume button, and four are arranged circumferentially to form a four-pointed star shape, so as to achieve the purpose of breaking up the air outlet. Similarly, in order to further enhance the sense of disorder of the air outlet, each adjacent group of holes and slots adopts a 60° phase difference array distribution arrangement. With the above structure, the natural wind feeling performance and the direct blowing protection requirements can be met at the same time.

[0062] Here, the effect that can be achieved by using the air guide plate 2 of this embodiment is described:

[0063] At present, the evaluation index of natural wind in the industry is generally the power spectrum density index β value and the turbulence intensity of the airflow. It is generally believed that 1.1<β<2 is used as the basis for judging natural wind. The air guide plate 2 built in this embodiment is equipped with natural wind control logic, and the β value is 1.448, which meets the natural wind standard. According to the evaluation guide book KCPWD50040372 for anti-direct blowing and soft wind sensing, under the anti-direct blowing or soft wind sensing function, the measured average wind speed value of the air guide plate 2 in various positions should be ≤0.6m / s.

[0064] First, according to the simulation results, Figure 8 , 9 As shown, it can be seen that the wind deflector 2 of this embodiment has a larger wind field upward angle than the original single-layer wind plate, and the ability to prevent direct blowing is improved; Fig.10 , 11 As shown, it can be seen that the wind guide plate 2 of this embodiment has a more obvious turbulence effect than the original single-layer wind plate, and the disorder and turbulence characteristics of the wind field are enhanced.

[0065] Then, according to the experimental results of the anti-direct blowing mode, such as Fig.12 , 13 As shown, it can be seen that in the original single-layer wind plate anti-direct blowing mode, the wind speed within a horizontal distance of 1m is relatively small, the average wind speed is <0.3m / s, and there is no wind feeling. The average wind speed at the measuring points (2,1.7) and (3,1.7) is >0.6m / s, which does not meet the anti-direct blowing standard. The wind guide plate 2 of this embodiment can increase the no wind feeling distance to 2m, and the average wind speed at each measuring point meets the anti-direct blowing standard, the average wind speed is reduced by 31.25%, and the anti-direct blowing ability is improved.

[0066] Finally, according to the experimental results of natural wind mode, such as Fig.14 , 15 As shown, it can be seen that in the natural wind mode, the wind field is highly volatile, presents a three-dimensional spatial distribution, and has no obvious periodicity. The 2β value of the wind guide plate in this embodiment is increased by 3.95% compared with the original single-layer wind plate, and the average turbulence is increased by 11.38% compared with the original wind plate, and the natural wind feeling is improved.

[0067] In some embodiments of the present application, Figure 6 , 7As shown, when the spoiler 23 is a hole slot, the spoiler 23 is in the shape of a long hole and extends along the length direction of the first plate 21, and the spoiler 23 is arranged at intervals along the width direction of the first plate 21. When the spoiler 23 is a hole slot, the air outlet of the air outlet 11 will be scattered when passing through the hole slot, achieving a natural wind feeling, and in order to further improve the effect of scattering the airflow, the present embodiment adopts a form of multiple groups of hole slots in cooperation with multiple spoilers 23, and the air outlet passes through multiple groups of hole slots, and the scattering effect is better, and the number of adjacent two groups of hole slots in the width direction is preferably different, for example, the spoiler 23 in the first group of hole slots is six, the spoiler 23 in the second group of hole slots is five, and the spoiler 23 in the third group of hole slots is six, and they are arranged in a cycle in sequence.

[0068] In some embodiments of the present application, when the spoiler 23 is a hole slot, the spoiler 23 is in the shape of a long hole and extends along the width direction of the first plate 21. When the spoiler 23 is a hole slot, the air from the air outlet 11 will be scattered when passing through the hole slot, achieving a natural wind feeling, and in order to further improve the effect of breaking up the airflow, the present embodiment adopts a method of arranging the spoilers 23 at intervals along the length direction, and each spoiler 23 will play a role in breaking up the air when the air passes through the first plate 21, thereby achieving the purpose of optimizing the natural wind feeling and improving the ability to prevent direct blowing.

[0069] In some embodiments of the present application, when the spoiler 23 is a convex block, the spoiler 23 is in a long strip shape and extends along the length direction of the first plate 21. When viewed from above the first plate 21, the center of the spoiler 23 extends from left to right in a broken line shape. When the spoiler 23 is a convex block, the air outlet of the air outlet 11 hits the convex block, and the air outlet will be scattered, achieving a natural wind feeling. In order to further enhance the effect of dispersing the airflow, the present embodiment adopts an irregular arrangement, and the spoilers 23 are staggered in both the length direction and the width direction of the first plate 21, thereby further enhancing the spoiler effect.

[0070] In some embodiments of the present application, when the spoiler 23 is a convex block, the spoiler 23 is in the shape of a long hole and extends along the length direction of the first plate 21, and the spoiler 23 is arranged at intervals along the width direction of the first plate 21. When the spoiler 23 is a convex block, the air outlet of the air outlet 11 hits the convex block, and the air outlet will be scattered, achieving a natural wind feeling, and in order to further enhance the effect of dispersing the airflow, the spoiler 23 of this embodiment is composed of multiple groups of convex blocks, and adjacent convex blocks are staggered, thereby further enhancing the spoiler effect.

[0071] In some embodiments of the present application, Figure 1-7As shown, the two ends of the first plate 21 and the second plate 22 in the width direction extend in a wave shape. The wave-shaped end design can play a role in breaking up the airflow, and with the above-mentioned spoiler 23 structure, it can play a better natural wind feeling and anti-direct blowing ability.

[0072] The second aspect of an embodiment of the present application proposes an air conditioner, comprising: an air conditioner indoor unit as described above; and an air conditioner outdoor unit, comprising a compressor and an outdoor heat exchanger, the compressor being used to compress and drive refrigerant, the indoor heat exchanger being connected to the compressor and the outdoor heat exchanger, and the outdoor heat exchanger being used to exchange heat with outdoor air. Based on the above technical solution, when the air conditioner is cooling, the outdoor heat exchanger in the air conditioner outdoor unit serves as a condenser, and the indoor heat exchanger in the air conditioner indoor unit serves as an evaporator to provide continuously circulating cold air for the indoor room. In order to improve the efficiency of indoor heat exchange, a fan is also provided on the inner side of the air outlet 11 of the air conditioner indoor unit. The fan blows out the cold air from the indoor heat exchanger, and the air guide plate 2 of the present application is used to adjust the air outlet; when the air conditioner is heating, the outdoor heat exchanger in the air conditioner outdoor unit serves as an evaporator, and the indoor heat exchanger in the air conditioner indoor unit serves as a condenser to provide continuously circulating hot air for the indoor room. In order to improve the efficiency of indoor heat exchange, a fan is also provided on the inner side of the air outlet 11 of the air conditioner indoor unit. The fan blows out the hot air from the indoor heat exchanger, and the air guide plate 2 of the present application is used to adjust the air outlet.

[0073] In summary, in the air-conditioning indoor unit of the present application, the outer shell 1 serves as a carrier for accommodating the indoor heat exchanger, and an air outlet 11 is provided on it for air conditioning to discharge air. The indoor heat exchanger can exchange heat with the indoor air, thereby cooling or heating the indoor temperature. The rotating shaft on the air guide plate 2 cooperates with the outer shell 1 to rotate, thereby changing the air outlet angle to achieve functions such as blowing. The first plate 21 is closer to the air outlet 11 than the second plate 22, corresponding to the air outlet position. Therefore, a spoiler 23 is provided on the side of the first plate 21 near the top to effectively disperse the airflow. When the spoiler 23 is a hole and slot structure, the airflow can be dispersed from the hole and slot gap, and partially blown out from between the first plate 21 and the second plate 22, which has the effect of dispersing wind and disturbing the flow and improving the ability to prevent direct blowing. When the spoiler 23 is a convex block structure, the airflow hitting the spoiler 23 can also play the role of dispersing wind and disturbing the flow and improving the ability to prevent direct blowing.

[0074] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
