Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning indoor unit. Background Art

[0002] The traditional four-way installation consists of two parts, the panel and the body, which results in the need for two different types of assembly lines for production. At the same time, the panel and the body are quite different, which requires separate packaging and transportation, and also requires separate installation during installation. In addition, the panel generally has 4-8 air outlets, including 4 main air outlets and 4 auxiliary air outlets. Due to the structure of the whole machine, the air volume of the 4 main air outlets is different, which affects the uniformity of indoor distribution. The single air guide plate structure is affected by the position of the return air outlet and cannot achieve a wide range of air supply angles and effectively adjust the outlet speed. The air volume of the auxiliary air outlet is only 10% of that of the main air outlet, and the outlet wind speed is lower than 2m / s. At the same time, the air supply angle is limited to prevent the return air from short-circuiting due to the fact that the inlet and return air outlets are in the same plane. The general opening angle range is about 30° to 60°. In order to prevent condensation, the air guide plate has a 6mm gap around the panel, which causes the cold air to overflow and blow directly to the user, resulting in a poor user experience. In addition, the panel needs additional insulation and a limited opening angle of the air guide plate shape to prevent condensation.

[0003] In summary, it is urgent to design an air-conditioning indoor unit to solve the above technical problems. Summary of the invention

[0054] The air conditioner of the present invention 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 to cool or heat the indoor space.

[0055] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas 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.

[0056] 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 low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling 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.

[0057] 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.

[0058] 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.

The control module is configured to adjust the opening angle of the air guide component 400 according to the operating mode, and is also configured to adjust the swing angle of the air guide component 400 according to the difference ΔT between the set room temperature and the real room temperature.

[0066] In some embodiments of the present invention, continue to refer to Figure 4 As shown, a plurality of air guide components 400 are provided, and are evenly arranged at the periphery of the housing 100. When the housing 100 is a rectangular cube, the number of the air guide components 400 can be four, and they are distributed at four connection points between the housing 100 and the panel component 300.

[0067] The panel assembly 300 includes a panel body 310 and a water receiving part 320, which are an integrally formed structure; the whole machine is manufactured, installed and transported as a whole, and the panel body 310 and the water receiving part 320 are combined with heat-insulating materials. The combination of components reduces manufacturing costs and working hours, and eliminates the insulation assembly required by the original product. The bottom of the water receiving part 320 and the housing 100 are both provided with an installation groove for matching the installation of the air guide assembly 400.

[0068] In some embodiments of the present invention, reference Figure 5As shown, the first air guide structure 410 includes a first air guide member 411, a second air guide member 412, a third air guide member 413 and a fourth air guide member 414 connected in sequence, the first air guide member 411 and the third air guide member 413 are arranged in parallel with each other, and the second air guide member 412 and the fourth air guide member 414 are arc-shaped members; further, the first air guide member 411, the second air guide member 412, the third air guide member 413 and the fourth air guide member 414 can be an integrally formed structure to enhance the structural strength of the first air guide structure 410, and the outer sides of the second air guide member 412 and the fourth air guide member 414 are both provided with a driving member 415, and the driving member 415 is connected to the control module for adjusting the swing angle of the first air guide structure 410. Further, the driving member 415 is a motor drive shaft, which is connected to the motor and can adjust the rotation angle of the first air guide structure 410 according to the instruction of the control module.

[0069] In some embodiments of the present invention, reference Figure 7-Figure 9 As shown, the cross section of the first air guide structure 410 is a rectangle, one of the corners of the rectangle is rounded, and the air outlet 430 formed by it is a rectangle, which is a jet-type air outlet 430, which can realize a large amount of air supply and quickly even the indoor temperature.

[0070] When the air outlet 430 is parallel to the panel assembly 300, that is, when the angle between the air outlet 430 and the horizontal direction is 0°, the first air guide structure 410 is in a horizontal air supply mode. Figure 7 As shown, in general, the horizontal air supply mode can be used in the cooling mode to achieve cold air settling; when the air outlet 430 is perpendicular to the panel assembly 300, that is, when the angle between the air outlet 430 and the horizontal direction is 90°, the first air guide structure 410 is in the vertical air supply mode; refer to Fig. 9 As shown, in general, the vertical air supply mode can be used in the heating mode to achieve direct hot air blowing. Both the cold air settling and the hot air blowing are for the purpose of quickly reaching the set indoor temperature. In addition, the control module is configured to adjust the first air guide structure 410 to rotate at any angle between the horizontal air supply mode and the vertical air supply mode, specifically referring to Figure 8 As shown, the control module can adjust the first air guiding structure 410 to rotate within the range of 0° to 90°.

[0071] In some embodiments of the present invention, reference Figure 5 and Figure 6As shown, the second wind guide structure 420 includes a wind guide body 421 and a connecting member 422, wherein the connecting member 422 runs through the wind guide body 421 and is rotatably connected to the first wind guide structure 410; the control module is configured to communicate with the connecting member 422 to adjust the swing angle of the second wind guide structure 420. The second wind guide structure 420 mainly cooperates with the first wind guide structure 410 to further adjust the wind speed and direction at the air outlet 430.

[0072] In some embodiments of the present invention, the second wind guide structure 420 also includes a connecting fitting 423 and a conductive member 424. The connecting fitting 423 is disposed in the wind guide body 421 and used in conjunction with the connecting member 422. The connecting member 422 is magnetic and electrically connected to the conductive member 424. The control module is configured to adjust the current of the conductive member 424 to control the rotation speed and swing angle of the wind guide body 421.

[0073] That is to say, a connecting fitting 423 is provided in the air guide body 421, which can be specifically an oil-containing metal sleeve. After the connecting fitting 422 passes through the connecting fitting 423 and the air guide body 421, it is connected to the second air guide 412 and the fourth air guide 414. The connecting fitting 422 is an electromagnetic shaft, and the connecting fitting 423 and the air guide body 421 can rotate around the connecting fitting 422. In addition, the connecting fitting 422 is connected to the conductive member 424, and the control module can adjust the magnetic flux of the connecting fitting 422 by adjusting the current in the conductive member 424, and the rotation speed of the air guide body 421 can be controlled by the change of magnetic force, and completely free rotation to stagnation can be achieved. When simulating natural wind, the current in the conductive member 424 can be discretely changed by MAX-MIN, and the air guide body 421 presents irregular rotation, which is beneficial when the fan motor has a constant speed and the current is constant. The non-changing current is beneficial to protecting the wind drive and extending the service life.

[0074] In some embodiments of the present invention, the connecting member 422 passes through the middle of the air guide body 421, and the air guide body 421 is formed of curved panels on both sides of the connecting member 422, but the bending directions of the two curved panels are opposite. This design can effectively adjust the wind direction.

[0075] In some embodiments of the present invention, the air guide body 421 is provided with a plurality of hollow portions 4211, and the hollow portions 4211 can effectively reduce wind resistance and high-speed and low-speed airflow mixing, thereby improving comfort. Figure 5 As shown, the area of ​​the hollow portion 4211 located in the middle is larger than the area of ​​the hollow portions 4211 located on both sides.

[0076] In some embodiments of the present invention, the panel assembly 300 includes a panel body 310 and a water receiving part 320, wherein the water receiving part 320 is a water receiving tray, and the panel body 310 and the water receiving part 320 are an integrally formed structure; the whole machine is manufactured, installed and transported as a whole, and the panel water receiving tray is combined with insulating materials. The combination of components reduces manufacturing costs and working hours, and eliminates the insulation assembly required for the original product.

[0077] In some embodiments of the present invention, the panel assembly 300 further includes a grille 330, and the grille 330 is fixedly connected to the panel body 310 to serve as a return air outlet of the air conditioner indoor unit.

[0078] In some embodiments of the present invention, a Hall position sensor is provided on one side of the air outlet 430, which is connected to the control module and is used to collect the rotation position of the second air guide structure 420 and send it to the control module. The position of the second air guide structure 420 can also be controlled by magnetic force changes.

[0079] The structure of the present invention can be installed, packaged, transported and manufactured as a whole at one time without changing the size of the installation hook. Some components can be combined through structural optimization and process optimization to improve production efficiency and reduce material usage. The EPP body structure can reduce the splicing and pasting of local insulation.

[0080] The control principle of the control module on the rotation angle of the air guide assembly 400 in the heating mode and the cooling mode will be described in detail below.

[0081] In heating mode

[0082] In some embodiments of the present invention, in the heating mode, it is necessary to achieve direct blowing of hot air. Since the quality of the hot air is low, the air outlet 430 needs to be as vertical as possible to facilitate the hot air to be dispersed throughout the room as quickly as possible.

[0083] When the heating mode is turned on, the control module is configured to adjust the first air guide structure 410 to an opening angle α; at this time, the opening angle α is 75°, that is, the air outlet 430 is 75° relative to the horizontal direction. In this embodiment, the maximum opening angle of the first air guide structure 410 and the second air guide structure 420 is 75°. In other words, when the heating mode is just entered, the opening angles of the first air guide structure 410 and the second air guide structure 420 are first adjusted to the maximum opening angle.

[0084] Then the timing starts. After t1 time, for example, 10 minutes, the control module collects the indoor temperature at this moment and calculates the difference ΔT between it and the set room temperature.

[0085] If ΔT reaches above the threshold, the control module is configured to reduce the opening angle α of the first air guide structure 410, that is, to adjust the opening angle to 60°, and control the swing amplitude of the second air guide structure 420 to swing periodically according to the following formula:

[0086] ;

[0087] Where t is time, N is motor speed; its maximum value is not greater than the opening angle α; refer to Fig.10 As shown, the second air-guiding structure 420 mainly swings at a large angle, with a large swing amplitude, and the airflow is vertically supplied, and the hot air can reach the ground directly. At the same time, the large swing is conducive to improving the temperature uniformity in the house. That is to say, after the second air-guiding structure 420 swings for 3 minutes according to the above formula, it stops for 5 minutes and circulates to time t2. The stop position of the second air-guiding structure 420 is the position of the maximum opening angle. After time t2, for example, after 20 minutes, the control module collects the indoor temperature at this moment and calculates the difference ΔT between it and the set room temperature. If ΔT reaches below the threshold, the air-guiding component 400 enters a stable state. If ΔT reaches above the threshold, the control module continues to reduce the opening angle α of the first air-guiding structure 410, and the second air-guiding structure 420 continues to swing periodically according to the above formula.

[0088] If ΔT reaches below the threshold, the air guide assembly 400 enters a stable state, and the control module is configured to periodically adjust the opening angle α of the first air guide structure 410 from large to small and then to large, for example, the changing order is 60°, 65°, 70°, 65°, 60°, for example, once every 10 minutes. The control module is also configured to adjust the second air guide structure to enter a free swinging state.

[0089] In the free swinging state, the control module is configured to control the swing amplitude of the second air guide structure 420 to swing periodically according to the following formula:

[0090] ;

[0091] Among them, t is time and N is the motor speed.

[0092] At this time, refer to Fig.12 As shown, the second air guide structure 420 oscillates and swings to achieve vertical air supply. In a stable state, the control module collects the indoor temperature every t3 time and calculates the difference ΔT.

[0093] In some embodiments of the present invention, when the difference ΔT is determined for the first time and the difference ΔT reaches a threshold value or above, if the control module is configured to reduce the opening angle α of the first air guide structure 410, that is, when the opening angle is adjusted to 65°, the second air guide structure 420 is adjusted according to the formula After swinging for 5 minutes, stop for 5 minutes, and the stop position of the second air guide structure 420 is the position of the maximum opening angle. After t2 time, for example, 10 minutes later, the control module collects the indoor temperature at this moment and calculates the difference ΔT between it and the set room temperature, and continues to judge the difference ΔT and the threshold value. The control module adjusts the angle of the air guide component 400 according to the judgment structure.

[0094] In cooling mode

[0095] In some embodiments of the present invention, in cooling mode, it is necessary to prevent cold air from blowing directly because the cold air has a large mass, so the air outlet 430 needs to be in a parallel direction as much as possible to avoid the cold air blowing on people.

[0096] When the cooling mode is turned on, the control module is configured to adjust the first air guide structure to an opening angle β; specifically, when the set temperature is 16-20 degrees, the default opening angles of the first air guide structure 410 and the second air guide structure 420 are 35 degrees; when the set temperature is 21-26 degrees, the default opening angles of the first air guide structure 410 and the second air guide structure 420 are 30 degrees

[0097] Then the timing starts. After t1 time, for example, 10 minutes, the control module collects the indoor temperature at this moment and calculates the difference ΔT between it and the set room temperature.

[0098] If ΔT reaches above the threshold, the control module is configured to increase the opening angle β of the first air guide structure 410, for example, the opening angle is 40°, and control the swing amplitude of the second air guide structure 420 to swing periodically according to the following formula:

[0099] ;

[0100] Where t is time, N is motor speed; its maximum value is not greater than 60% of the opening angle β; refer to Fig.11 As shown, the second air guiding structure 420 mainly swings at a small angle, the swing amplitude is small, and the airflow is delivered horizontally to prevent cold wind from blowing on people.

[0101] That is to say, when the set temperature is 16-20 degrees, the second air-guiding structure 420 swings according to the above formula for 3 minutes, stops for 5 minutes and cycles to t2 time, and the stop position of the second air-guiding structure 420 is the position of the maximum opening angle. After t2 time, for example, 20 minutes later, the control module collects the indoor temperature at this moment and calculates the difference ΔT between it and the set room temperature. If ΔT reaches below the threshold, the air-guiding component 400 enters a stable state. If ΔT reaches above the threshold, the control module continues to increase the opening angle β of the first air-guiding structure 410, and the second air-guiding structure 420 continues to swing periodically according to the above formula. When the set temperature is 21-26 degrees, the second air-guiding structure 420 swings according to the above formula for 5 minutes, stops for 1 minute and cycles to t2 time, and the stop position of the second air-guiding structure 420 is the position of the maximum opening angle. After time t2, for example 20 minutes later, the control module collects the current indoor temperature and calculates the difference ΔT between it and the set room temperature. If ΔT reaches below the threshold, the air guide assembly 400 enters a stable state. If ΔT reaches above the threshold, the control module continues to increase the opening angle β of the first air guide structure 410, and the second air guide structure 420 continues to oscillate periodically according to the above formula.

[0102] When the difference ΔT reaches below the threshold, the air guide assembly 400 enters a stable state, the control module is configured to reduce the rotation speed of the fan assembly 200, for example, by one gear, and the control module is further configured to adjust the second air guide structure 420 to enter a free swinging state.

[0103] In some embodiments of the present invention, in the free swinging state, the control module is configured to control the swing amplitude of the second air guide structure 420 to swing periodically according to the following formula:

[0104] ;

[0105] Among them, t is time and N is the motor speed.

[0106] At this time, refer to Fig.12 As shown, the second air guide structure 420 oscillates and swings to achieve horizontal air supply. In a stable state, the control module collects the indoor temperature every t3 time and calculates the difference ΔT.

[0107] The present invention has the following beneficial effects:

[0108] The air guide structure provided in the present invention can solve the problem of uneven airflow at the air outlet. At the same time, the control module is used to adjust the rotation angle of the air guide structure 400 according to data such as the operating mode and indoor temperature to achieve the effect of rapid and uniform indoor temperature distribution. In addition, the design of the jet-type air outlet realizes ultra-long-distance air supply.

[0109] In heating mode, the control module adjusts the second air guide structure 420 to swing according to the formula to simulate natural wind. The second air guide structure 420 swings mainly at a large angle, with a large swing amplitude, and the airflow is vertically supplied, and the hot air can reach the ground directly. At the same time, the large swing is conducive to improving the indoor temperature. In cooling mode, the control module adjusts the second air guide structure 420 to swing according to the formula to simulate natural wind. The second air guide structure 420 swings mainly at a small angle, with a small swing amplitude, and the airflow is horizontally supplied to prevent cold wind from blowing on people.

[0111] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
