[0050] Due to the adoption of the air conditioner and control method thereof with a combination of multiple air supply modes proposed by the present invention, during the operation of the air conditioner, the two centrifugal fans 27, the two separate air ducts, the two air supply cylinders, and the rotation of the volute 24 and the volute 23 realize the air supply mode of all-up, all-down, and simultaneous upper and lower air outlets, and upper, middle, and lower baffles that can slide left and right are respectively arranged at the connection between the two air supply cylinders and the two air ducts, and the six baffles are controlled to slide left and right to realize the left and right partitioned combined air supply of the two air supply cylinders for the upper, middle, and lower three areas; at the same time, by detecting and recording the air conditioner set temperature, indoor temperature, and outdoor temperature in real time, the six baffles that can slide left and right are adjusted and controlled according to the difference between the three to realize the use of different air supply mode combinations under different operating conditions, and the opening and closing of the two centrifugal fans 27 are combined to realize multiple combinations of different air supply modes in multiple working conditions and regions, thereby solving the discomfort caused by the long-term operation of a single air supply mode, meeting the comfort requirements of users in different working conditions under the cooling / heating mode, realizing partitioned centralized air supply for different human activity areas, and improving the overall comfort of the room during the operation of the air conditioner.

[0051] Embodiment 2 of the present invention provides an air conditioner indoor unit, which includes an air outlet device, which is the air outlet device provided in embodiment 1. The first air supply part 11 and the second air supply part 12 of the air outlet device are part of the indoor unit housing 10.

[0052] The air conditioner with multiple air supply modes and its control method proposed in this patent realize multiple combinations of different air supply modes in multiple working conditions and regions by controlling the start-up of two fans 27 and the opening and closing of the upper, middle and lower air supply areas of the left and right cylinders. It solves the discomfort caused by long-term operation of a single air supply mode, meets the comfort needs of users in different working conditions in cooling / heating mode, and improves the overall comfort of the room during air-conditioning operation.

[0053] The implementation methods of different air supply modes are as follows: the air conditioner mentioned in this patent includes two centrifugal fans 27, two separate air duct structures 20, and two air supply cylinders. The rotation of the volute 24 and the volute 23 realizes full-up, full-down, and simultaneous up and down air outlets, and upper, middle, and lower baffles that can slide left and right are respectively arranged at the connection between the two air supply cylinders and the two air ducts. By controlling the six baffles to slide left and right, the left and right air supply cylinders can perform left and right partitioned combined air supply for the upper, middle, and lower three areas.

[0054] Specifically, the structures of the fan 27, the air duct, the air supply cylinder and the baffle are as follows: Figure 3As shown, two centrifugal fans 27 are placed vertically, and the left and right air ducts are independent of each other. The left air duct is responsible for the upper air supply on the left side, the middle air supply on the right side and the lower air supply area, and the right air duct is responsible for the upper air supply on the right side, the middle air supply on the left side and the lower air supply area. Different air supply modes and zoned combined air supply are achieved by sliding the upper, middle and lower baffles at the connection between the left and right air ducts and the left and right air supply cylinders.

[0055] Specifically, the different air supply modes mainly include three different air supply modes: all-up, all-down, and both up and down air supply. Among them, the switching of the air supply modes is mainly achieved by the rotation of the volute tongue 24 and the volute 23. Figure 1 and Figure 2 As shown: when the volute tongues 24 of the two fans 27 are rotated to the bottom of the air duct, the opening directions of the two volutes 23 are upward, and the full-up air supply mode can be achieved. When the volute tongues 24 of the two fans 27 are rotated to the top of the air duct, the opening directions of the two volutes 23 are upward, and the full-down air supply mode can be achieved.

In this way, the comfort of air outlet is improved.

With such a structural setting, the flexibility of the air supply direction can be improved, so as to improve the comfort of air supply.

[0059] In this embodiment, the air outlet device provided above is adopted, and the three first air outlets 21 of the air outlet device are the first upper air outlet, the first middle air outlet and the first lower air outlet, and the three second air outlets 22 of the air outlet device are the second upper air outlet, the second middle air outlet and the second lower air outlet; during cooling, the method of controlling the air outlet of the first air outlet 21 or the second air outlet 22 according to the comparison result of ΔTout and T3 includes: when ΔTout≤T3, controlling the air outlet of the first upper air outlet and the first lower air outlet, or controlling the air outlet of the second upper air outlet and the second lower air outlet; when ΔTout>T3, controlling the air outlet of the first upper air outlet and / or the second upper air outlet. The use of such a structural setting can facilitate further optimization of the air supply method and improve the air supply comfort.

[0060] Specifically, during cooling, the method of controlling the air outlet of the first air outlet 21 or the second air outlet 22 according to the comparison result of ΔTout and T2 includes: when ΔTout≤T2, controlling the air outlet of the first upper air outlet, the first middle air outlet and the first lower air outlet, or controlling the air outlet of the second upper air outlet, the second middle air outlet and the second lower air outlet; when ΔTout>T2, controlling the air outlet of the first upper air outlet and the first middle air outlet, or controlling the air outlet of the second upper air outlet and the second middle air outlet.

[0061] In this embodiment, the air outlet device provided above is adopted, and the three first air outlets 21 of the air outlet device are the first upper air outlet, the first middle air outlet and the first lower air outlet, and the three second air outlets 22 of the air outlet device are the second upper air outlet, the second middle air outlet and the second lower air outlet; when heating, the method of controlling the air outlet of the first air outlet 21 or the second air outlet 22 according to the comparison result of ΔTout and T3 includes: when ΔTout≤T3, controlling the first middle air outlet and / or the second middle air outlet to discharge air; when ΔTout>T3, controlling the first lower air outlet and / or the second lower air outlet to discharge air.

[0063] The specific implementation plan of zoned combined air supply with different air supply modes is as follows:

[0064] Specific implementation plan for refrigeration conditions:

[0065] like Figure 4As shown, when the air conditioner is turned on for cooling, an infrared detector or temperature sensor is used to detect the current room's indoor temperature tin and outdoor temperature tout. The current air conditioner set temperature is tc, and △tin is defined as the difference between the current indoor temperature tin and the air conditioner set temperature tc, and △tout is defined as the difference between the current outdoor temperature tout and the indoor temperature tin.

[0066] First, determine the relationship between the current indoor temperature and the air conditioning set temperature:

[0067] (1) If the difference between the current room air conditioner set temperature tc and the indoor temperature tin is less than or equal to t1, further determine the relationship between the current room temperature and the outdoor temperature.

[0068] 1) If the difference between the current room outdoor temperature tout and the indoor temperature tin is less than and equal to t3, it indicates that the difference between the air-conditioning set temperature and the indoor temperature is relatively small, but the indoor temperature that is comfortable for the human body has not yet been reached, and the cooling mode still needs to be turned on. At this time, the upper fan 27 volute 23 is controlled to face upward (downward), and the lower fan 27 volute 23 is controlled to face downward (upward), the upper and lower baffles of the left (right) air supply cylinder are opened, and the middle baffle is closed to avoid the discomfort caused by cold wind blowing directly on the human body, and to achieve simultaneous air supply on one side and up and down of the left and right partitions.

[0069] 2) If the difference between the current room outdoor temperature tout and the indoor temperature tin is greater than t3, it indicates that the air conditioner is in the late stage of cooling operation and the indoor temperature has reached a relatively stable state. At this time, it is only necessary to control the volute 23 of the upper and lower fans 27 to face upward, open the upper baffles of the left and right air supply cylinders, and close the middle and lower baffles. This can realize single or simultaneous upper air supply in the left and right partitions, avoiding the discomfort caused by cold air accumulating on the ground during the stable stage of the air conditioner.

[0070] (2) If the difference between the current room air conditioner set temperature tc and the indoor temperature tin is greater than t1, further determine the relationship between the current room temperature and the outdoor temperature.

[0071] 1) If the difference between the current room outdoor temperature tout and the indoor temperature tin is less than and equal to t2, it indicates that the air conditioner is in the cooling operation stage where the air conditioner is just turned on. The indoor temperature is high and the air conditioner needs to be cooled quickly. By controlling the upper fan 27 volute 23 to face upward (downward) and the lower fan 27 volute 23 to face downward (upward), the upper, middle and lower baffles of the left (right) air supply cylinder are opened to realize the simultaneous supply of cold air on the upper, middle and lower sides of the left (right) partition.

[0072] 2) If the difference between the current room outdoor temperature tout and the indoor temperature tin is greater than t2, it indicates that the air conditioner has been running for a period of time and the indoor temperature has gradually decreased, but has not yet reached a stable state. It is necessary to control the upper fan 27 volute 23 to face upward (downward) and the lower fan 27 volute 23 to face downward (upward), open the upper and middle baffles of the left (right) air supply cylinder, and close the lower baffle to avoid cold air accumulation on the ground and cause a large vertical temperature difference in the air. The left (right) partition can be simultaneously supplied with air on one side, to meet the needs of users in different living areas.

[0073] Specific implementation plan for heating conditions:

[0074] When the air conditioner is turned on for heating, Figure 5 As shown, an infrared detector or a temperature sensor is used to detect the indoor temperature tin and the outdoor temperature tout of the current room. The current set temperature of the air conditioner is th, and △tin is defined as the difference between the set temperature th of the air conditioner and the current indoor temperature tin, and △tout is defined as the difference between the current indoor temperature tin and the outdoor temperature tout.

[0075] First, determine the relationship between the current indoor temperature and the air conditioning set temperature:

[0076] (1) If the difference between the current room air conditioner set temperature tc and the indoor temperature tin is less than or equal to t1, further determine the relationship between the current room temperature and the outdoor temperature.

[0077] 1) If the difference between the current room outdoor temperature tout and the indoor temperature tin is less than and equal to t3, it indicates that the difference between the air-conditioning set temperature and the indoor temperature is relatively small, and the indoor heat supply required is small but the heating mode still needs to be turned on. At this time, the upper and lower fans 27 volutes 23 are controlled downward, the left (right) air supply cylinder middle baffle is opened, and the upper and lower baffles are closed, so that the left and right partitions can be divided into single middle or simultaneous middle air supply, which meets the demand for hot air to warm the body and avoids the phenomenon of hot air sticking to the ground.

[0078] 2) If the difference between the current room outdoor temperature tout and the indoor temperature tin is greater than t3, it indicates that the air conditioner is in the late stage of heating operation and the air conditioner heating reaches the temperature point. At this time, you only need to control the upper and lower fan 27 volute 23 downward, open the lower baffles of the left and right air supply cylinders, and close the upper and middle baffles. This can realize the left and right partition single downward or simultaneous downward air supply, avoiding the problem of hot head and cold feet caused by long-term operation of the air conditioner.

[0079] (2) If the difference between the current room air conditioner set temperature tc and the indoor temperature tin is greater than t1, further determine the relationship between the current room temperature and the outdoor temperature.

[0080] 1) If the difference between the current room outdoor temperature tout and the indoor temperature tin is less than and equal to t2, it indicates that the air conditioner is in the heating operation stage just started, and the indoor temperature is relatively low, and the air conditioner needs to achieve rapid heating. By controlling the upper fan 27 volute 23 to face upward (downward) and the lower fan 27 volute 23 to face downward (upward), the upper, middle and lower baffles of the left (right) air supply cylinder are opened, and hot air is delivered simultaneously on the upper, middle and lower sides of the left (right) partition.

[0081] 2) If the difference between the current room outdoor temperature tout and the indoor temperature tin is greater than t2, it indicates that the air conditioner has been running for heating for a period of time, but has not yet reached the temperature point. It is necessary to control the upper and lower fans 27 volutes 23 downward, open the middle and lower baffles of the left (right) air supply cylinder, and close the upper baffle to prevent hot air from sticking to the ceiling. It is also possible to achieve single-side middle and lower air supply in the left and right partitions or simultaneous middle and lower air supply.

[0082] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: solve the discomfort caused by a single air supply mode to the human body during the long-term operation of the air conditioner; solve the problem that the air supply mode of the i-type cabinet and the distributed cabinet is single and cannot realize the centralized air supply for the human body or a certain area of ​​the room. Due to the use of the air conditioner and its control method with multiple air supply mode combinations proposed by the present invention, by detecting and recording the air conditioner set temperature, indoor temperature and outdoor temperature in real time, adjusting and controlling the six sliding baffles of the left and right air supply cylinders according to the difference between the three, different air supply mode combinations are realized under different operating conditions, and the opening and closing of the two centrifugal fans are combined to realize multiple combinations of different air supply modes in different working conditions and regions, which solves the discomfort caused by the long-term operation of a single air supply mode, meets the comfort requirements of users in different working conditions under the cooling / heating mode, can realize centralized air supply in different areas of human activity, and improves the overall comfort of the room during the operation of the air conditioner.
