Description

Technical Field

Background Art

[0002] With the development of air conditioner technology, the comfort of using an air conditioner has become the primary demand of users. In particular, some functions that can assist in improving the comfort during the use of an air conditioner, such as the air sweep mode of the air conditioner, can help improve the comfort when the user uses the air conditioner. In the air sweep mode of the air conditioner, the air sweep is turned on by changing the air flow direction of cold air or hot air to improve the user's comfort. However, in the related solutions, the air sweep method of the air conditioner is relatively simple, such as only controlled by the opening and closing of the air sweep mechanism, without considering the overall comfort of the user using the air conditioner, which is not conducive to improving the comfort of the user using the air conditioner.

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Considering that in the relevant schemes, the air sweeping mode of the air conditioner is divided into left and right sweeping or up and down sweeping. Generally, the air sweeping is controlled by simply adjusting the wind direction after turning on the sweeping mode. The sweeping mode basically relies on a single sweeping speed to sweep back and forth. Due to the difference in the density of cold and hot air, the cold air may be blown directly or blown to the ground after the differentiated use of the sweeping, and the hot air may float on the ceiling, resulting in uneven cold and hot, making the overall comfort effect of the air conditioner poor. This sweeping method is relatively mechanized and relatively single, which may cause problems such as uneven cold and hot, such as: the problem of alternating cold and hot in the sweeping mode in the cooling mode, and the problem of hot air always on the ceiling in the heating mode, resulting in uneven cold and hot. Therefore, in order to solve the problem that the air sweeping mode of the air conditioner in the related scheme is not conducive to improving the comfort of users using the air conditioner by only controlling the air sweeping mode of the air conditioner by opening and closing the air sweeping mechanism, the scheme of the present invention proposes a control method for an air conditioner, specifically a control method for improving indoor comfort by sweeping up and down the air conditioner, so as to optimize the comfort of the up and down sweeping function by relying on the up and down air outlet dual-track dual-drive air duct control system of the air conditioner, and the large and small air guide plates arranged at the air outlet of the air conditioner are used to make the air blown out by the air conditioner circulate to the maximum extent, thereby effectively improving the temperature uniformity in the whole room in the cooling mode, and effectively reducing the temperature deviation of the room after the air sweeping is turned on in the heating mode, thereby ensuring the indoor cooling or heating effect and improving the comfort of users using the air conditioner.

[0031] According to an embodiment of the present invention, a control method for an air conditioner is provided, as Figure 1 shown in the flowchart of an embodiment of the method of the present invention. The air conditioner has an indoor unit, and the indoor unit has an air outlet. A wind deflector is provided at the air outlet. The wind deflector includes a first wind deflector and a second wind deflector. The first wind deflector is like the large wind deflector 10, and the second wind deflector is like the small wind deflector 20. The first wind deflector can adjust the air outlet direction of the air outlet, and the second wind deflector can sweep up and down within the air outlet range of the air outlet to realize the up and down sweeping function of the air conditioner. Specifically, Figure 4 is a schematic structural diagram of an embodiment of the up and down sweeping range of the air conditioner, Figure 5 is a schematic structural diagram of another embodiment of the up and down sweeping range of the air conditioner. As Figure 4 and Figure 5 shown, the sweeping mechanism of the air conditioner includes the large wind deflector 10 and the small wind deflector 20 provided at the air outlet of the air conditioner. The large wind deflector 10 can adjust the air outlet direction of the air outlet of the air conditioner, and the small wind deflector 20 has the up and down sweeping function and can sweep up and down within the air outlet range of the air outlet of the air conditioner.

[0032] As Figure 4 and Figure 5 shown, the air conditioner optimizes the comfort of the up and down sweeping function by relying on the up and down air outlet double-rail double-drive air duct control system. Among them, the up and down sweeping function of the air conditioner is to make the air blown out from the air outlet of the air conditioner circulate to the maximum extent through the large and small wind deflectors (such as the large wind deflector 10 and the small wind deflector 20) provided at the air outlet of the air conditioner, so as to ensure the cooling effect or heating effect in the room. The control method of the air conditioner includes: step S110 to step S150.

[0033] In step S110, when the air conditioner is turned on and the up and down sweeping function of the air conditioner is turned on, determine the current operating mode of the air conditioner.

[0034] In step S120, according to the current operating mode of the air conditioner, control the first wind deflector to be in the default position in the current operating mode of the air conditioner, such as the position where the large wind deflector 10 is located in the cooling mode, the position where the large wind deflector 10 is located in the heating mode, etc. Preferably, it can be Figure 4 and Figure 5 shown in the example that the large wind deflector 10 is opened to the maximum position. And according to the current operating mode of the air conditioner, determine the movement trajectory of the second wind deflector during the up and down sweeping, which is recorded as the current trajectory of the second wind deflector.

[0035] Among them, the current operating mode of the air conditioner is a cooling mode or a heating mode. The movement trajectory of the second air deflector for up-and-down air sweeping within the air outlet range includes: a full trajectory and a partial trajectory. The full trajectory is the movement trajectory of the second air deflector for up-and-down air sweeping within the entire range of the air outlet range, and the partial trajectory is the movement trajectory of the second air deflector for up-and-down air sweeping within a partial range of the air outlet range. The partial range of the air outlet range is a part of the entire range of the air outlet range, or in other words, the partial range of the air outlet range is smaller than the entire range of the air outlet range.

[0036] In some embodiments, in step S120, according to the current operating mode of the air conditioner, the movement trajectory of the second air deflector during up-and-down air sweeping is determined, denoted as the current trajectory of the second air deflector, including any of the following determination cases:

[0037] The first determination case: If the current operating mode of the air conditioner is the cooling mode, then it is determined that the movement trajectory of the second air deflector during up-and-down air sweeping is the full trajectory, denoted as the current trajectory of the second air deflector.

[0038] The second determination case: If the current operating mode of the air conditioner is the heating mode, then it is determined that the movement trajectory of the second air deflector during up-and-down air sweeping is the partial trajectory, denoted as the current trajectory of the second air deflector.

[0039] Specifically, Figure 6 is a schematic flow chart of an embodiment of a control method for improving indoor comfort by up-and-down air sweeping of an air conditioner in the cooling mode. Figure 7 is a schematic flow chart of an embodiment of a control method for improving indoor comfort by up-and-down air sweeping of an air conditioner in the heating mode. As Figure 6 and Figure 7 shown, in the cooling mode or the heating mode, the control method for improving indoor comfort by up-and-down air sweeping of the air conditioner includes:

[0040] Step 1: When the air conditioner is turned on and the up-and-down air sweeping mode of the air conditioner (i.e., the up-and-down air sweeping function of the air conditioner) is turned on, at this time, the large air deflector 10 is opened to the maximum position (as Figure 4 and Figure 5 shown, the large air deflector 10 is opened to one edge of the air outlet, such as the lower edge position), and up-and-down air sweeping is performed by the up-and-down movement of the small air deflector 20. During the process of the small air deflector 20 performing up-and-down air sweeping within the air outlet range of the air conditioner, among the positions passed by the small air deflector 20 from top (i.e., the upper edge of the air outlet of the air conditioner) to bottom (i.e., the lower edge of the air outlet of the air conditioner), there are successively distributed a first position 1, a second position 2, and a third position 3.

[0041] Step 2: In the cooling mode, the movement trajectory of the small air deflector 20 is from the first position 1 to the third position 3 (i.e., from the first position 1 through the second position 2 to the third position 3), that is, the small air deflector 20 moves through the full trajectory (i.e., the operating trajectory from the first position 1 to the third position 3) to improve the cooling comfort.

[0042] Step 3: In the heating mode, the movement trajectory of the small air deflector 20 is from the first position 1 to the second position 2. Since the hot air has a small density and is likely to float in the upper part of the indoor space, the movement trajectory does not reach the third position 3 at this time to improve the temperature difference between the upper and lower parts of the room.

[0043] In some embodiments, within the air outlet range of the air outlet, in the direction from the upper edge to the lower edge of the air outlet, the positions where the second air deflector is located include a first position, a second position, and a third position. The first position is the first position 1 as shown in Figure 4 and Figure 5 shown, the second position is the second position 2 as shown in Figure 4 and Figure 5 shown, and the third position is the third position 3 as shown in Figure 4 and Figure 5 shown. Then: the full trajectory is the movement trajectory of the second air deflector for sweeping up and down between the first position and the third position, and the partial trajectory is the movement trajectory of the second air deflector for sweeping up and down between the first position and the second position.

[0044] Wherein, the second air deflector has a rotating end and a sweeping end. The rotating end is fixed at a set position on the indoor unit housing and can rotate as the sweeping end moves. The sweeping end realizes up and down sweeping through up and down movement. The first position is the position where the second air deflector is located when the sweeping end moves to the upper edge of the air outlet, the second position is the position where the second air deflector is located when the sweeping end moves to a position between the upper edge and the lower edge of the air outlet, and the third position is the position where the second air deflector is located when the sweeping end moves to the lower edge of the air outlet.

[0045] See Figure 4 and Figure 5In the example shown, the first position 1 can be a position where the outer end of the small air deflector 20 (i.e., the end of the small air deflector 20 far from the air outlet) is located at a preset rotation position, and the inner end of the small air deflector 20 (i.e., the end of the small air deflector 20 close to the air outlet) is located inside the upper edge of the air outlet. The second position 2 can be a position where the outer end of the small air deflector 20 (i.e., the end of the small air deflector 20 far from the air outlet) is located at a preset rotation position, and the inner end of the small air deflector 20 (i.e., the end of the small air deflector 20 close to the air outlet) is located between the inner side of the upper edge of the air outlet and the inner side of the lower edge of the air outlet. The third position 3 can be a position where the outer end of the small air deflector 20 (i.e., the end of the small air deflector 20 far from the air outlet) is located at a preset rotation position, and the inner end of the small air deflector 20 (i.e., the end of the small air deflector 20 close to the air outlet) is located inside the lower edge of the air outlet.

[0046] In some embodiments, the second position is the position where the second air deflector is located when the sweeping end moves to the middle position between the upper edge and the lower edge of the air outlet. Based on the rotation end, the angle between the first position and the second position is 32° to 38°, preferably 35°; the angle between the second position and the third position is 37° to 43°, preferably 40°. For example: Denote the line connecting the rotation end to the first position as the first line, the line connecting the rotation end to the second position as the second line, and the line connecting the rotation end to the third position as the third line. Then: the angle between the first line and the second line is 32° to 38° and preferably 35°, and the angle between the second line and the third line is 37° to 43° and preferably 40°.

[0047] See Figure 4 and Figure 5 In the example shown, preferably, the angle between the first position 1 and the second position 2 can be about 35°, the angle between the second position 2 and the third position 3 can be about 40°, and the angle between the first position 1 and the third position 3 can be about 75°. Here, the setting of the angle between the first position 1 and the second position 2 enables the best temperature rise effect of the air-conditioning system during heating. For example, the temperature rise rate can reach 0.9 °C / min under the rated heating condition. The setting of the angle between the second position 2 and the third position 3 enables the best temperature drop effect of the air-conditioning system during cooling. For example, the temperature drop rate can reach 1 °C / min under the rated cooling condition.

[0048] At step S130, in the current operating mode of the air conditioner, control the second air deflector to move along the current trajectory of the second air deflector, that is, control the second air deflector to move along the current trajectory during the up-and-down sweeping process to implement the up-and-down sweeping function of the second air deflector.

[0049] At step S140, in the current operating mode of the air conditioner, when the second air deflector moves along the current trajectory of the second air deflector, that is, when the second air deflector moves along the current trajectory during the up-and-down air sweeping process, obtain the target temperature of the air conditioner and the current indoor ambient temperature of the air conditioner. The target temperature is, for example, the current set temperature Ts, and the current indoor ambient temperature is, for example, the current actually detected temperature Td.

[0050] At step S150, in the current operating mode of the air conditioner, according to the target temperature of the air conditioner and the current indoor ambient temperature of the air conditioner, adjust the up-and-down air sweeping speed during the up-and-down air sweeping of the second air deflector, that is, adjust the up-and-down air sweeping speed during the process that the second air deflector moves along the current trajectory of the second air deflector, so as to quickly and evenly make the current indoor ambient temperature of the air conditioner reach the target temperature of the air conditioner in the current operating mode of the air conditioner, and improve the user's comfort in using the air conditioner.

[0051] A control method for improving indoor comfort by up-and-down air sweeping of an air conditioner proposed by the solution of the present invention optimizes the comfort of the up-and-down air sweeping function by using large and small air deflectors (i.e., large air deflector 10 and small air deflector 20) provided at the air outlet of the air conditioner and relying on the up-and-down air outlet dual-rail and dual-drive air duct control system of the air conditioner, so that the air blown out by the air conditioner can circulate maximally, effectively improve the temperature uniformity in the whole room in the cooling mode, effectively reduce the temperature deviation in the room after the air sweeping is turned on in the heating mode, ensure the cooling or heating effect indoors, and improve the user's comfort in using the air conditioner. Among them, both the up-and-down air outlet systems are realized by the cooperation of dual air deflectors (i.e., large air deflector 10 and small air deflector 20). Specifically, it is realized by the coupled movement of the small air deflector 20 and the large air deflector 10. The small air deflector 20 rotates at the air outlet through a motor to guide the air at the air outlet, and the large air deflector 10 controls the opening and closing of the air deflector through a motor guide rail.

[0052] In some embodiments, the specific process of adjusting the up-and-down air sweeping speed during the up-and-down air sweeping of the second air deflector at step S150 in the current operating mode of the air conditioner according to the target temperature of the air conditioner and the current indoor ambient temperature of the air conditioner is as follows in the following exemplary description.

[0053] The following combination Figure 2Schematic diagram of an embodiment of the process of adjusting the up-and-down air-sweeping speed during the up-and-down air-sweeping of the second air deflector in the method of the present invention, further illustrating the specific process of adjusting the up-and-down air-sweeping speed during the up-and-down air-sweeping of the second air deflector in step S160, including: steps S210 to S230.

[0054] Step S210, in the current operating mode of the air conditioner, determine the absolute value of the temperature difference between the target temperature of the air conditioner and the current indoor ambient temperature of the air conditioner, such as the difference ΔT between the current set temperature Ts and the current actually detected temperature Td, and determine whether the absolute value of this temperature difference is less than or equal to the set temperature. The set temperature is, for example, 1°C.

[0055] Step S220, in the current operating mode of the air conditioner, if it is determined that the absolute value of this temperature difference is less than or equal to the set temperature, then determine the up-and-down air-sweeping speed during the up-and-down air-sweeping of the second air deflector as the first set speed, and control the second air deflector to sweep up and down at the first set speed during the up-and-down air-sweeping process.

[0056] Step S230, in the current operating mode of the air conditioner, if it is determined that the absolute value of this temperature difference is greater than the set temperature, then determine the up-and-down air-sweeping speed during the up-and-down air-sweeping of the second air deflector as the second set speed, and control the second air deflector to sweep up and down at the second set speed during the up-and-down air-sweeping process. The second set speed is greater than the first set speed.

[0057] Specifically, as Figure 6 and Figure 7 shown, in the cooling mode or the heating mode, the control method for the air conditioner to sweep up and down to improve indoor comfort further includes: in the cooling mode, step 2 specifically includes the following steps 21 to 23, and in the heating mode, step 3 specifically includes the following steps 31 to 33.

[0058] Among them, in the cooling mode, in step 21, based on the current set temperature Ts and the current actually detected temperature Td detected by the air conditioner, determine the difference ΔT between the current set temperature Ts and the current actually detected temperature Td, and adjust the up-and-down air-sweeping speed Vs of the small air deflector 20 according to this difference ΔT. Specifically, determine whether this difference ΔT is greater than 1°C: if so, execute step 22, otherwise execute step 23.

[0059] Step 22: When the temperature difference ΔT > 1°C, during the process of the small air deflector 20 moving up and down for sweeping according to the full trajectory (i.e., the movement trajectory from the first position 1 to the third position 3), the up and down sweeping speed Vs of the small air deflector 20 operates at a speed of Vs = the second set speed S2. This is because when the currently detected actual detected temperature Td has not reached the user-set temperature (i.e., the current set temperature Ts), and the indoor ambient temperature (i.e., the currently detected actual detected temperature Td) is relatively high, the room temperature drop effect is enhanced by rapid sweeping.

[0060] Step 23: When the temperature difference ΔT ≤ 1°C, it indicates that the room temperature (i.e., the currently detected actual detected temperature Td) basically meets the user's usage requirements. At this time, the up and down sweeping speed Vs of the small air deflector 20 operates at a speed of Vs = the first set speed S1. The up and down sweeping speed Vs of the small air deflector 20 is relatively slow, and it can slowly maintain or even improve the usage comfort uniformity under relatively energy-saving conditions. Among them, the second set speed S2 > the first set speed S1, and both the first set speed S1 and the second set speed S2 are in the range of 10 ms / step to 40 ms / step.

[0061] In the heating mode, Step 31: Determine the temperature difference ΔT between the current set temperature Ts and the current actual detected temperature Td detected by the air conditioner, and adjust the up and down sweeping speed Vs of the small air deflector 20 according to this temperature difference ΔT. Specifically, it is judged whether the temperature difference ΔT is greater than 1°C: if so, execute Step 32; otherwise, execute Step 33.

[0062] Step 32: When the temperature difference ΔT > 1°C, during the process of the small air deflector 20 moving up and down for sweeping according to the movement trajectory from the first position 1 to the second position 2, the up and down sweeping speed Vs of the small air deflector 20 operates at a speed of Vs = the second set speed S2. This is because when the currently detected actual detected temperature Td has not reached the user-set temperature (i.e., the current set temperature Ts), and the indoor ambient temperature (i.e., the currently detected actual detected temperature Td) is relatively low, the room temperature rise effect is enhanced by rapid sweeping.

[0063] Step 33: When the temperature difference ΔT ≤ 1°C, at this time the room temperature (i.e., the currently detected actual detected temperature Td) basically meets the user's usage requirements. At this time, the up and down sweeping speed Vs of the small air deflector 20 operates at a speed of Vs = the first set speed S1. The up and down sweeping speed Vs of the small air deflector 20 is relatively slow, and it can slowly maintain or even improve the usage comfort uniformity under relatively energy-saving conditions. Among them, the second set speed S2 > the first set speed S1.

[0064] The solution of the present invention utilizes the large and small air deflector plates (i.e., the large air deflector plate 10 and the small air deflector plate 20) provided at the air outlet of the air conditioner, and relies on the up-and-down air outlet dual-rail and dual-drive air duct control system of the air conditioner to optimize the comfort of the up-and-down air sweeping function. By differentiating the up-and-down air sweeping speeds of the small air deflector plate 20 in different modes, the comfort of users using the air conditioner in different modes is improved.

[0065] Adopting the technical solution of this embodiment, for an air conditioner with an up-and-down air outlet dual-rail and dual-drive air duct control system, a large air deflector plate 10 and a small air deflector plate 20, and the small air deflector plate 20 having an up-and-down air sweeping function, utilize the large and small air deflector plates (i.e., the large air deflector plate 10 and the small air deflector plate 20) provided at the air outlet of the air conditioner, and rely on the up-and-down air outlet dual-rail and dual-drive air duct control system of the air conditioner. In the cooling mode, the air sweeping range of the up-and-down air sweeping of the small air deflector plate 20 is the full range (i.e., the full trajectory from the first position 1 to the third position 3). In the heating mode, the air sweeping range of the up-and-down air sweeping of the small air deflector plate 20 is a partial range (i.e., the partial trajectory from the first position 1 to the second position 2), and in the cooling mode and the heating mode, respectively, adjust the up-and-down air sweeping speed of the small air deflector plate 20 according to the temperature difference between the detected value and the set value of the indoor environmental temperature, and adjust the up-and-down air sweeping speed of the small air deflector plate 20 according to the temperature difference between the detected value and the set value of the indoor environmental temperature. Thus, through the large and small air deflector plates provided at the air outlet of the air conditioner, the air blown out by the air conditioner can be circulated maximally, ensuring the cooling or heating effect indoors and improving the comfort of users using the air conditioner.

[0066] According to an embodiment of the present invention, there is also provided a control device for an air conditioner corresponding to the control method of the air conditioner. Refer to Figure 3 The structural schematic diagram of an embodiment of the device of the present invention shown. The air conditioner has an indoor unit, and the indoor unit has an air outlet. At the air outlet, there is an air deflector plate, and the air deflector plate includes a first air deflector plate and a second air deflector plate. The first air deflector plate is like the large air deflector plate 10, and the second air deflector plate is like the small air deflector plate 20. The first air deflector plate can adjust the air outlet direction of the air outlet, and the second air deflector plate can sweep up and down within the air outlet range of the air outlet to achieve the up-and-down air sweeping function of the air conditioner. Specifically, Figure 4 The structural schematic diagram of an embodiment of the up-and-down air sweeping interval of the air conditioner, Figure 5 The structural schematic diagram of another embodiment of the up-and-down air sweeping interval of the air conditioner. As Figure 4 and Figure 5 shown, the air sweeping mechanism of the air conditioner includes the large air deflector plate 10 and the small air deflector plate 20 provided at the air outlet of the air conditioner. The large air deflector plate 10 can adjust the air outlet direction of the air outlet of the air conditioner, and the small air deflector plate 20 has an up-and-down air sweeping function and can sweep up and down within the air outlet range of the air outlet of the air conditioner.

[0067] As Figure 4 and Figure 5 shown in the air conditioner, by relying on the up-and-down air outlet double-track and double-drive air duct control system of the air conditioner, the comfort of the up-and-down air-sweeping function is optimized. Among them, the up-and-down air-sweeping function of the air conditioner is realized by the large and small air deflectors (such as the large air deflector 10 and the small air deflector 20) arranged at the air outlet of the air conditioner, so that the air blown out from the air outlet of the air conditioner can circulate to the maximum extent, thereby ensuring the cooling or heating effect in the room. The control device of the air conditioner includes: an acquisition unit 102 and a control unit 104.

[0068] Among them, the control unit 104 is configured to determine the current operating mode of the air conditioner when the air conditioner is turned on and the up-and-down air-sweeping function of the air conditioner is turned on. The specific functions and processes of this control unit 104 are referred to in step S110.

[0069] The control unit 104 is further configured to control the first air deflector to be in the default position in the current operating mode of the air conditioner according to the current operating mode of the air conditioner, such as the position of the large air deflector 10 in the cooling mode, the position of the large air deflector 10 in the heating mode, etc. Preferably, it can be Figure 4 and Figure 5 In the examples shown in, the large air deflector 10 is opened to the maximum position. And according to the current operating mode of the air conditioner, determine the movement trajectory of the second air deflector during the up-and-down air-sweeping process, which is recorded as the current trajectory of the second air deflector. The specific functions and processes of this control unit 104 are also referred to in step S120.

[0070] Among them, the current operating mode of the air conditioner is the cooling mode or the heating mode. The movement trajectory of the second air deflector for up-and-down air-sweeping within the air outlet range of the air outlet includes: a full trajectory and a partial trajectory. The full trajectory is the movement trajectory of the second air deflector for up-and-down air-sweeping within the entire range of the air outlet range of the air outlet, and the partial trajectory is the movement trajectory of the second air deflector for up-and-down air-sweeping within a partial range of the air outlet range of the air outlet. The partial range of the air outlet range is a part of the entire range of the air outlet range, or in other words, the partial range of the air outlet range is smaller than the entire range of the air outlet range.

[0071] In some embodiments, the control unit 104 determines the movement trajectory of the second air deflector during the up-and-down air-sweeping process according to the current operating mode of the air conditioner, which is recorded as the current trajectory of the second air deflector, including any of the following determination cases:

[0072] The first determination case: The control unit 104 is specifically further configured to determine that the movement trajectory of the second air deflector during the up-and-down air sweeping process is the full trajectory when the current operating mode of the air conditioner is the cooling mode, which is denoted as the current trajectory of the second air deflector.

[0073] The second determination case: The control unit 104 is specifically further configured to determine that the movement trajectory of the second air deflector during the up-and-down air sweeping process is the partial trajectory when the current operating mode of the air conditioner is the heating mode, which is denoted as the current trajectory of the second air deflector.

[0074] Specifically, Figure 6 is a schematic flowchart of an embodiment of a control device for improving indoor comfort by up-and-down air sweeping of an air conditioner in the cooling mode. Figure 7 is a schematic flowchart of an embodiment of a control device for improving indoor comfort by up-and-down air sweeping of an air conditioner in the heating mode. As Figure 6 and Figure 7 shown, in the cooling mode or the heating mode, a control device for improving indoor comfort by up-and-down air sweeping of an air conditioner includes:

[0075] Step 1: When the air conditioner is turned on and the up-and-down air sweeping mode of the air conditioner (i.e., the up-and-down air sweeping function of the air conditioner) is turned on, at this time, the large air deflector 10 is opened to the maximum position (as shown in Figure 4 and Figure 5 shown, the large air deflector 10 is opened to one edge of the air outlet, such as the lower edge position), and up-and-down air sweeping is performed by the up-and-down movement of the small air deflector 20. During the process of the small air deflector 20 performing up-and-down air sweeping within the air outlet range of the air conditioner, among the positions passed by the small air deflector 20 from top (i.e., the upper edge of the air outlet of the air conditioner) to bottom (i.e., the lower edge of the air outlet of the air conditioner), there are successively distributed the first position 1, the second position 2, and the third position 3.

[0076] Step 2: In the cooling mode, the movement trajectory of the small air deflector 20 is from the first position 1 to the third position 3 (i.e., the first position 1 passes through the second position 2 and then reaches the third position 3), that is, the small air deflector 20 moves through the full trajectory (i.e., the operating trajectory from the first position 1 to the third position 3) to improve the cooling comfort.

[0077] Step 3: In the heating mode, the movement trajectory of the small air deflector 20 is from the first position 1 to the second position 2. Since the hot air has a small density and is easy to float in the upper part of the indoor space, at this time, the movement trajectory does not reach the third position 3 to improve the temperature difference between the upper and lower parts of the room.

[0078] In some embodiments, within the air outlet range of the air outlet, in the direction from the upper edge of the air outlet to the lower edge of the air outlet, it is set that the positions where the second air deflector is located include the first position, the second position, and the third position. The first position is asFigure 4 and Figure 5 the first position 1 shown in, the second position is as Figure 4 and Figure 5 the second position 2 shown in, the third position is as Figure 4 and Figure 5 the third position 3 shown in, then: the full trajectory is the movement trajectory of the second air deflector sweeping up and down between the first position and the third position, and the partial trajectory is the movement trajectory of the second air deflector sweeping up and down between the first position and the second position.

[0079] Wherein, the second air deflector has a rotating end and a sweeping end, the rotating end is fixed at a set position on the indoor unit housing and can rotate as the sweeping end moves, and the sweeping end realizes up and down air sweeping through up and down movement. The first position is the position of the second air deflector when the sweeping end moves to the upper edge of the air outlet, the second position is the position of the second air deflector when the sweeping end moves to a position between the upper edge and the lower edge of the air outlet, and the third position is the position of the second air deflector when the sweeping end moves to the lower edge of the air outlet.

[0080] See Figure 4 and Figure 5 the example shown in, the first position 1 can be the position where the outer end of the small air deflector 20 (i.e., the end of the small air deflector 20 away from the air outlet) is located at a preset rotating position and the inner end of the small air deflector 20 (i.e., the end of the small air deflector 20 close to the air outlet) is located inside the upper edge of the air outlet. The second position 2 can be the position where the outer end of the small air deflector 20 (i.e., the end of the small air deflector 20 away from the air outlet) is located at a preset rotating position and the inner end of the small air deflector 20 (i.e., the end of the small air deflector 20 close to the air outlet) is located between the inner side of the upper edge and the inner side of the lower edge of the air outlet. The third position 3 can be the position where the outer end of the small air deflector 20 (i.e., the end of the small air deflector 20 away from the air outlet) is located at a preset rotating position and the inner end of the small air deflector 20 (i.e., the end of the small air deflector 20 close to the air outlet) is located inside the lower edge of the air outlet.

[0081] In some embodiments, the second position is the position where the second air deflector is located when the swing end moves to the middle position between the upper edge and the lower edge of the air outlet. Based on the rotation end, the angle between the first position and the second position is 32° to 38°, preferably 35°; the angle between the second position and the third position is 37° to 43°, preferably 40°. For example: Denote the line connecting the rotation end and the first position as the first line, the line connecting the rotation end and the second position as the second line, and the line connecting the rotation end and the third position as the third line. Then: the angle between the first line and the second line is 32° to 38°, and preferably 35°, and the angle between the second line and the third line is 37° to 43°, and preferably 40°.

[0082] See Figure 4 and Figure 5 the example shown. Preferably, the angle between the first position 1 and the second position 2 can be about 35°, the angle between the second position 2 and the third position 3 can be about 40°, and the angle between the first position 1 and the third position 3 can be about 75°.

[0083] The control unit 104 is further configured to control the second air deflector to move along the current trajectory of the second air deflector in the current operating mode of the air conditioner, that is, to control the second air deflector to move along the current trajectory during the up and down swing process to implement the up and down swing function of the second air deflector. For the specific functions and processes of this control unit 104, also refer to step S130.

[0084] The acquisition unit 102 is configured to acquire the target temperature of the air conditioner and the current indoor environmental temperature of the air conditioner in the current operating mode of the air conditioner when the second air deflector moves along the current trajectory of the second air deflector, that is, when the second air deflector moves along the current trajectory during the up and down swing process. The target temperature is, for example, the current set temperature Ts, and the current indoor environmental temperature is, for example, the current actually detected temperature Td. For the specific functions and processes of this acquisition unit 102, refer to step S140.

[0085] The control unit 104 is further configured to adjust the up-and-down sweeping speed of the second air deflector during the up-and-down sweeping process according to the target temperature of the air conditioner and the current indoor environmental temperature of the air conditioner in the current operating mode of the air conditioner, that is, to adjust the up-and-down sweeping speed of the second air deflector during the process of the second air deflector moving along the current trajectory of the second air deflector, so as to quickly and evenly reach the target temperature of the air conditioner for the current indoor environmental temperature of the air conditioner in the current operating mode of the air conditioner, and improve the user comfort of using the air conditioner. For the specific functions and processes of this control unit 104, refer to step S150

[0086] A control device for improving indoor comfort by up-and-down sweeping of an air conditioner proposed by the solution of the present invention uses large and small air deflectors (i.e., large air deflector 10 and small air deflector 20) provided at the air outlet of the air conditioner, and relies on the up-and-down air outlet dual-track and dual-drive air duct control system of the air conditioner to optimize the comfort of the up-and-down sweeping function, so that the air blown out by the air conditioner can circulate maximally, effectively improving the temperature uniformity in the whole room in the cooling mode, effectively reducing the temperature deviation in the room after the sweeping is turned on in the heating mode, ensuring the cooling or heating effect indoors, and improving the user comfort of using the air conditioner.

[0087] In some embodiments, the control unit 104 adjusts the up-and-down sweeping speed of the second air deflector during the up-and-down sweeping process according to the target temperature of the air conditioner and the current indoor environmental temperature of the air conditioner in the current operating mode of the air conditioner, including:

[0088] The control unit 104 is specifically further configured to determine the absolute value of the temperature difference between the target temperature of the air conditioner and the current indoor environmental temperature of the air conditioner in the current operating mode of the air conditioner, such as the difference ΔT between the current set temperature Ts and the current actual detected temperature Td, and determine whether the absolute value of the temperature difference is less than or equal to the set temperature. The set temperature is, for example, 1°C. For the specific functions and processes of this control unit 104, refer to step S210.

[0089] The control unit 104 is specifically further configured to determine that the up-and-down sweeping speed of the second air deflector during the up-and-down sweeping process is the first set speed and control the second air deflector to sweep up and down at the first set speed during the up-and-down sweeping process if it is determined that the absolute value of the temperature difference is less than or equal to the set temperature in the current operating mode of the air conditioner. For the specific functions and processes of this control unit 104, refer to step S220.

[0090] The control unit 104 is further specifically configured to, in the current operating mode of the air conditioner, if it is determined that the absolute value of the temperature difference is greater than the set temperature, determine that the up-down swing speed of the second air deflector during the up-down swing is the second set speed, and control the second air deflector to swing up and down at the second set speed during the up-down swing. The second set speed is greater than the first set speed. For the specific functions and processing of the control unit 104, refer to step S230.

[0091] Specifically, as Figure 6 and Figure 7 shown, in the cooling mode or heating mode, the control device for improving indoor comfort by the up-down swing of the air conditioner further includes: in the cooling mode, step 2 specifically includes the following steps 21 to 23, and in the heating mode, step 3 specifically includes the following steps 31 to 33.

[0092] Among them, in the cooling mode, in step 21, the difference ΔT between the current set temperature Ts and the current actual detected temperature Td detected by the air conditioner is determined, and the up-down swing speed Vs of the small air deflector 20 is adjusted according to the difference ΔT. Specifically, it is determined whether the difference ΔT is greater than 1°C: if so, step 22 is executed; otherwise, step 23 is executed.

[0093] In step 22, when the difference ΔT > 1°C, during the process of the small air deflector 20 swinging up and down by moving along the full trajectory (i.e., the running trajectory from the first position 1 to the third position 3), the up-down swing speed Vs of the small air deflector 20 runs at the speed of Vs = the second set speed S2. This is because when the currently detected actual detected temperature Td has not reached the user-set temperature (i.e., the current set temperature Ts) and the indoor ambient temperature (i.e., the currently detected actual detected temperature Td) is relatively high, the temperature drop effect of the room is improved by fast swinging.

[0094] In step 23, when the difference ΔT ≤ 1°C, it indicates that the room temperature (i.e., the currently detected actual detected temperature Td) basically meets the user's usage requirements. At this time, the up-down swing speed Vs of the small air deflector 20 runs at the speed of Vs = the first set speed S1. The up-down swing speed Vs of the small air deflector 20 is relatively slow, and the use comfort and uniformity can be slowly maintained or even improved under relatively energy-saving conditions. Among them, the second set speed S2 > the first set speed S1.

[0095] In the heating mode, in step 31, based on the current set temperature Ts and the current actual detected temperature Td detected by the air conditioner, the difference ΔT between the current set temperature Ts and the current actual detected temperature Td is determined, and the up and down sweeping speed Vs of the small air deflector 20 is adjusted according to this difference ΔT. Specifically, it is judged whether the difference ΔT is greater than 1°C: if so, step 32 is executed; otherwise, step 33 is executed.

[0096] In step 32, when the difference ΔT > 1°C, during the process of the small air deflector 20 sweeping up and down along the running track from the first position 1 to the second position 2, the up and down sweeping speed Vs of the small air deflector 20 runs at a speed of Vs = the second set speed S2. This is because when the currently detected actual detected temperature Td does not reach the user-set temperature (i.e., the current set temperature Ts) and the indoor environmental temperature (i.e., the currently detected actual detected temperature Td) is relatively low, the room temperature rise effect is improved by quickly sweeping the air.

[0097] In step 33, when the difference ΔT ≤ 1°C, at this time the room temperature (i.e., the currently detected actual detected temperature Td) basically meets the user's usage requirements. At this time, the up and down sweeping speed Vs of the small air deflector 20 runs at a speed of Vs = the first set speed S1. The up and down sweeping speed Vs of the small air deflector 20 is relatively slow, and it can slowly maintain or even improve the usage comfort and uniformity under the condition of relatively energy saving. Among them, the second set speed S2 > the first set speed S1.

[0098] The solution of the present invention uses the large and small air deflectors (i.e., the large air deflector 10 and the small air deflector 20) provided at the air outlet of the air conditioner, and relies on the up and down air outlet double-track and double-drive air duct control system of the air conditioner to optimize the comfort of the up and down air sweeping function. Through the differential design of the up and down air sweeping speed of the small air deflector 20 in different modes, the usage comfort of the user using the air conditioner in different modes is improved.

[0099] Since the processing and functions implemented by the device in this embodiment are basically corresponding to the embodiments, principles and examples of the foregoing method, for the parts not described in detail in the description of this embodiment, reference can be made to the relevant descriptions in the foregoing embodiments, and details will not be repeated here.

[0100] Adopting the technical solution of the present invention, for an air conditioner with an upper and lower air outlet double-rail double-drive air duct control system, a large air deflector 10 and a small air deflector 20, and the small air deflector 20 having an up-and-down air sweeping function, by using the large and small air deflectors (i.e., the large air deflector 10 and the small air deflector 20) provided at the air outlet of the air conditioner, relying on the upper and lower air outlet double-rail double-drive air duct control system of the air conditioner, in the cooling mode, the air sweeping range of the up-and-down air sweeping of the small air deflector 20 is the full range (i.e., the full trajectory from the first position 1 to the third position 3), in the heating mode, the air sweeping range of the up-and-down air sweeping of the small air deflector 20 is a partial range (i.e., the partial trajectory from the first position 1 to the second position 2), and in the cooling mode and the heating mode respectively, the up-and-down air sweeping speed of the small air deflector 20 is adjusted according to the temperature difference between the detected value and the set value of the indoor ambient temperature, and the up-and-down air sweeping speed of the small air deflector 20 is adjusted according to the temperature difference between the detected value and the set value of the indoor ambient temperature, effectively improving the temperature uniformity in the whole room in the cooling mode, effectively reducing the temperature deviation in the room after the air sweeping is turned on in the heating mode, and enhancing the user's comfort in using the air conditioner.
