[0038] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] Please refer to Figures 1 to 6 The first aspect of the present application provides an anti-condensation device, which comprises an anti-condensation structure 1 installed at the air outlet 20 of an air outlet panel 2, the anti-condensation structure being arranged between an air outlet frame 3 located at the air outlet 20 and the air outlet 20, one end of the anti-condensation structure 1 being located inside the air outlet panel 2, and the other end of the anti-condensation structure 1 being arranged outside the air outlet panel 2; wherein the anti-condensation structure 1 is movably arranged between the air outlet frame 3 and the air outlet 20, so as to adjust the circumferential position of the anti-condensation structure 1 at the air outlet 20, and make different parts of the anti-condensation structure 1 face the air outlet direction of the air outlet frame 3.

[0040] It can be seen that the anti-condensation device provided by the present application can block the edge of the air outlet 20 close to the outer side of the air outlet panel 2 by the anti-condensation structure 1, and at the same time, when the anti-condensation structure 1 is adjusted in the circumferential direction of the air outlet 20 between the air outlet frame 3 and the air outlet 20, different parts of the anti-condensation structure 1 can be arranged towards the air outlet direction of the air outlet frame 3, so that the different parts of the anti-condensation structure 1 are evenly cooled, thereby avoiding the phenomenon that the part of the air outlet panel 2 in the air outlet direction is excessively cooled and causes a temperature difference between the part and the remaining part, resulting in condensation of the air outlet panel 2 under the condition of high air humidity, thereby optimizing the phenomenon that the air outlet panel 2 condenses more under the condition of high air humidity, and reducing the phenomenon that the condensation drips or is blown out by the wind, and improving the comfort of the user. The anti-condensation device has a simple structure, is convenient to maintain, and can effectively solve the problem that the panel of the air conditioner in the prior art is prone to condensation when the air guide blade is fixed in a certain direction.

[0041] Specifically, one end of the anti-condensation structure 1 is arranged outside the edge close to the air outlet panel 2 in the air outlet 20.

[0042] Specifically, since the air outlet direction of the air outlet frame 3 has a certain air outlet range, and part of the anti-condensation structure 1 is located in the air outlet range, when the anti-condensation structure 1 is adjusted in the circumferential direction of the air outlet 20, the part of the anti-condensation structure 1 located at the air outlet direction position (i.e., the air outlet range) of the air outlet frame 3 will gradually move away from the air outlet direction position (i.e., the air outlet range) of the air outlet frame 3 according to the preset direction, and the remaining part of the anti-condensation structure 1 will gradually enter the air outlet direction position (i.e., the air outlet range) of the air outlet frame 3, so that different parts of the anti-condensation structure 1 are arranged towards the air outlet direction of the air outlet frame 3.

[0043] Therefore, the different parts of the anti-condensation structure 1 can be understood as including at least part of the part of the anti-condensation structure 1 newly entering the air outlet direction position (i.e., the air outlet range) and the part of the anti-condensation structure 1 previously located in the air outlet direction position (i.e., the air outlet range).

[0044] Further, the preset direction refers to the track of the anti-condensation structure 1 set by the researchers according to the shape of the air outlet 20 and the air outlet direction of the air outlet frame 3 before the anti-condensation device leaves the factory, which can be moving in a certain direction or reciprocating in a certain direction.

[0045] In the embodiment, the anti-condensation structure 1 is an arc-shaped plate structure, and the anti-condensation structure 1 is movably arranged along the circumferential direction of the air outlet 20.

[0051] When the anti-condensation structure 1 rotates along the circumferential direction of the air outlet 20, different parts of the anti-condensation structure 1 will gradually rotate to the position of the air outlet direction of the air outlet frame 3, so that different parts of the anti-condensation structure 1 are uniformly cooled, thereby reducing the condensation of the air outlet panel.

[0066] In actual work process, the cross-sectional area of the protection shell 63 can shield the driving gear 60, by adopting such structure, the protection shell 63 can protect the driving gear 60 and the driving member 62.

[0067] Specifically, the anti-condensation structure 1 is a circular ring structure, the rack 61 extends along the circumferential direction of the anti-condensation structure 1, and the corresponding central angle of the rack 61 is α, 180°≤α≤360°.

[0068] Preferably, the corresponding central angle (i.e. α) of the rack 61 is 180°. By adopting such structure, the complexity of processing can be reduced on the basis of effectively reducing the phenomenon of condensation on the air outlet panel 2, and the manufacturing cost is saved.

One rack 61 and the other rack 61 are engaged with the drive gear 60 to synchronously drive the two racks 61 to move through the drive gear 60.

[0071] Preferably, the drive gear 60 is located at the symmetry line position of the rack 61 (i.e. the drive gear 60 is located at the middle part of the rack 61).

[0072] In specific implementation process, as shown in Figure 1 and Figure 4 The anti-condensation device further comprises a limiting piece 7, the limiting piece 7 is connected with the air outlet panel 2, the limiting piece 7 is provided with a limiting groove, the limiting groove is matched with the shape of the anti-condensation structure 1, the limiting groove extends along the circumferential direction of the anti-condensation structure 1, and at least part of the anti-condensation structure 1 is arranged in the limiting groove to limit the movement direction of the anti-condensation structure 1.

[0073] Wherein, limiting the movement direction of the anti-condensation structure 1 refers to the direction of the movement of the anti-condensation structure 1 along the thickness direction of the air outlet panel 2.

[0074] In actual work process, the width of the limiting groove is greater than the thickness of the side wall of the anti-condensation structure 1, so that the anti-condensation structure 1 can be movably arranged in the limiting groove.

[0080] Specifically, taking the central angle corresponding to the rack 61 as 180° as an example, when the anti-condensation structure 1 starts to rotate, the drive gear 60 will first drive the rack 61 to rotate 90° clockwise, and then rotate 180° counterclockwise, and finally rotate 90° clockwise, so as to make the rack 61 return to the initial position, and at the same time, the adjacent left and right sides of the remaining parts of the anti-condensation structure 1 located at the position of the air outlet direction of the air outlet frame 3 when the anti-condensation structure 1 is not rotating can be rotated to the position of the air outlet direction of the air outlet frame 3, so that the anti-condensation structure 1 is uniformly cooled, and the phenomenon of excessive temperature difference is avoided, thereby reducing the phenomenon of condensation on the air outlet panel 2.

[0081] The second aspect of the present application provides an air conditioner comprising the anti-condensation device provided above.

The starting of the anti-condensation device refers to the power-on of the anti-condensation device, and the turning off of the anti-condensation device refers to the power-off of the anti-condensation device.

[0091] The environmental dew point temperature in the indoor environment is obtained by sensing the environmental dry-bulb temperature and the environmental wet-bulb temperature in the indoor environment through the temperature sensing bag of the air conditioner, and then obtaining the environmental dew point temperature in the indoor environment.

[0092] In the specific implementation process, the judgment of whether to turn off the anti-condensation device comprises:

[0093] comparing the temperature difference with a first preset temperature difference;

[0094] detecting the air supply mode of the air conditioner in the case of the temperature difference being greater than or equal to the first preset temperature difference, and judging whether to turn off the anti-condensation device according to the temperature difference and the air supply mode of the air conditioner;

[0095] in the case of the temperature difference being less than the first preset temperature difference, repeating the comparison of the temperature difference with the first preset temperature difference after a first preset time interval, and judging whether to turn off the anti-condensation device according to the comparison result of the temperature difference with the first preset temperature difference.

[0096] Specifically, the control method comprises the following steps:

[0097] In the case that the air conditioner is in the normal air supply mode, it is determined to refuse to close the anti-condensation device.

[0098] In the case that the air conditioner is in the air sweeping mode, the temperature difference is compared with the first preset temperature difference every interval of a predetermined time length, and it is determined whether to close the anti-condensation device according to the comparison result of the temperature difference and the first preset temperature difference.

[0099] The predetermined time length is less than the first preset time length.

[0100] Specifically, in the case that the air conditioner is in the air sweeping mode, the control method further comprises the following steps:

[0101] The temperature difference is compared with a second preset temperature difference.

[0102] In the case that the temperature difference is less than the second preset temperature difference, the temperature difference is compared with the first preset temperature difference and the second preset temperature difference after an interval of a second preset time length, and it is determined whether to close the anti-condensation device according to the comparison result of the temperature difference and the first preset temperature difference and the second preset temperature difference.

[0103] In the case that the temperature difference is greater than or equal to the second preset temperature difference, the temperature difference is compared with the first preset temperature difference and the second preset temperature difference after an interval of a third preset time length, and it is determined whether to close the anti-condensation device according to the comparison result of the temperature difference and the first preset temperature difference and the second preset temperature difference.

[0104] The second preset time length is greater than the third preset time length.

[0105] Specifically, the control method comprises the following steps:

[0106] The first preset temperature difference and the second preset temperature difference refer to the temperature difference set in the air conditioner by the technician according to the actual situation before leaving the factory. The first predetermined number and the second predetermined number refer to the detection number set in the air conditioner by the technician according to the actual situation before leaving the factory. The first preset time length, the second preset time length and the third preset time length refer to the time length set in the air conditioner by the technician according to the actual situation before leaving the factory. In the actual work process, the first preset temperature difference is set to 2°C, and the second preset temperature difference is set to 5°C. The first predetermined number and the second predetermined number are both set to 3 times. The first preset time length is 90 minutes, the second preset time length is 45 minutes, and the third preset time length is 30 minutes.

[0107] In the actual work process, when the air conditioner is in the cooling mode or the dehumidification mode, the air conditioner obtains the current indoor environment dew point temperature through the temperature sensing bag, compares the obtained indoor environment dew point temperature with the preset temperature, obtains the temperature difference between the indoor environment dew point temperature and the preset temperature, and compares the temperature difference with the first preset temperature difference and the second preset temperature difference.

[0108] The temperature difference between the indoor environment dew point temperature and the preset temperature is X.

[0109] When X < 2°C, the current indoor environment dew point temperature is obtained again after an interval of 90 minutes, the temperature difference is obtained, and if the temperature difference is still less than 2°C, the comparison is performed again after an interval of 90 minutes. If the temperature difference is still less than 2°C after continuous detection for 3 times, the anti-condensation device is turned off.

[0110] When X ≥ 2°C, the air supply mode of the air conditioner is obtained, and if the air conditioner is in the air sweeping mode, the air conditioner obtains the current indoor environment dew point temperature again after an interval of a preset time length, and obtains the temperature difference. If the obtained temperature difference is still within the range, the air supply mode of the air conditioner is obtained again, and if the air conditioner is still in the air sweeping mode, the above operation is repeated again after an interval of a preset time length. If the temperature difference obtained each time is greater than or equal to 2°C after continuous repetition for 3 times, and the air conditioner is in the air sweeping mode, the anti-condensation device is turned off.

[0111] When 5°C < X ≥ 2°C, the air conditioner obtains the current indoor environment dew point temperature again after an interval of 45 minutes, and when X ≥ 5°C, the air conditioner obtains the current indoor environment dew point temperature again after an interval of 30 minutes.

[0112] If the air conditioner is in the normal air supply mode (directional air supply mode), the anti-condensation device of the air conditioner is still started.

[0113] Specifically, the temperature difference value obtained by acquiring the current indoor ambient dew point temperature each time is compared with one of the three preset temperature difference value ranges, and a corresponding action is performed in correspondence.

[0114] In the embodiment, the operation of the anti-condensation structure of the anti-condensation device is controlled according to the temperature difference value, including: controlling the operation period of the predetermined anti-condensation operation of the anti-condensation structure according to the temperature difference value; wherein the operation period of the predetermined anti-condensation operation refers to the time interval between the anti-condensation structure moving from a predetermined position to the next time the anti-condensation structure is at the predetermined position.

[0115] In actual work process, the movement process of the anti-condensation structure (i.e. the trajectory of the anti-condensation structure moving once) is set according to the central angle of the rack corresponding to the anti-condensation device, first rotating the central angle of the rack corresponding to the anti-condensation device by one-half of the angle in the preset direction, then rotating the central angle of the rack corresponding to the anti-condensation device in the opposite direction of the preset direction, and finally rotating the central angle of the rack corresponding to the anti-condensation device by one-half of the angle in the preset direction. The time used in this process is the operation period of the predetermined anti-condensation operation (i.e. the time set for the anti-condensation structure to complete the above-mentioned action once).

[0116] Specifically, the operation period of the predetermined anti-condensation operation of the anti-condensation structure is controlled according to the temperature difference value, including: controlling the operation period of the predetermined anti-condensation operation of the anti-condensation structure according to the running time of the air conditioner and the temperature difference value.

[0117] Further, the operation period of the predetermined anti-condensation operation of the anti-condensation structure is controlled according to the running time of the air conditioner and the temperature difference value, including:

[0118] In the case that the temperature difference value is less than the fourth preset temperature difference value and greater than or equal to the first preset temperature difference value, the running time is compared with the first preset running time, and a first preset period range corresponding to the operation period is determined according to the comparison result of the running time and the first preset running time;

[0119] In the case that the temperature difference value is greater than or equal to the fourth preset temperature difference value and less than the fifth preset temperature difference value, the running time is compared with the second preset running time and the third preset running time, and a second preset period range corresponding to the operation period is determined according to the comparison result of the running time and the second preset running time and the third preset running time;

[0120] In the case that the temperature difference value is greater than the fifth preset temperature difference value, the running time is compared with the fourth preset running time and the fifth preset running time, and a third preset period range corresponding to the operation period is determined according to the comparison result of the running time and the fourth preset running time and the fifth preset running time;

[0121] The fourth preset temperature difference is greater than the first preset temperature difference, the first preset running time is between the second preset running time and the third preset running time, the third preset running time is greater than the second preset running time, the fifth preset running time is greater than the fourth preset running time, the fifth preset running time is less than the third preset running time, the fourth preset running time is less than or equal to the second preset running time, the minimum cycle of the third preset cycle range is less than the minimum cycle of the second preset cycle range, and the minimum cycle of the second preset cycle range is less than the minimum cycle of the first preset cycle range.

[0122] The fourth preset temperature difference and the fifth preset temperature difference refer to temperature differences set in the air conditioner by technicians according to actual conditions before leaving the factory. The first preset running time, the second preset running time, the third preset running time, the fourth preset running time, and the fifth preset running time refer to running time lengths set in the air conditioner by technicians according to actual conditions before leaving the factory.

[0123] Meanwhile, the first preset cycle range, the second preset cycle range, and the third preset cycle range refer to running cycles of the anti-condensation operation set by technicians before leaving the factory corresponding to different preset running time ranges.

[0124] In actual work, the fourth preset temperature difference is set to 3°C, the fifth preset temperature difference is set to 2°C, the first preset running time is set to 20 minutes, the second preset running time is set to 10 minutes, the third preset running time is set to 25 minutes, the fourth preset running time is set to 10 minutes, and the fifth preset running time is set to 20 minutes.

[0125] When the temperature difference is greater than or equal to 2°C and less than 3°C, when the air conditioner normal blowing mode running time is less than 20 minutes, the running cycle of the anti-condensation operation is 180 seconds, and when the air conditioner normal blowing mode running time is greater than or equal to 20 minutes, the running cycle of the anti-condensation operation is 120 seconds.

[0126] When the temperature difference is greater than or equal to 3°C and less than 5°C, when the air conditioner normal blowing mode running time is less than 10 minutes, the running cycle of the anti-condensation operation is 120 seconds, when the air conditioner normal blowing mode running time is greater than or equal to 10 minutes and less than 25 minutes, the running cycle of the anti-condensation operation is 190 seconds, and when the air conditioner normal blowing mode running time is greater than or equal to 25 minutes, the running cycle of the anti-condensation operation is 60 seconds.

[0127] When the temperature difference is greater than or equal to 5℃, the running period of the anti-condensation operation is 90 seconds when the running time of the air conditioner in the normal air supply mode is less than 10 minutes, the running period of the anti-condensation operation is 60 seconds when the running time of the air conditioner in the normal air supply mode is greater than or equal to 10 minutes and less than 20 minutes, and the running period of the anti-condensation operation is 30 seconds when the running time of the air conditioner in the normal air supply mode is greater than or equal to 25 minutes.

[0128] Further, when the temperature difference is greater than 5℃ and less than 5℃, the anti-condensation device is automatically powered off and stopped after running for 90 minutes; when the temperature difference is greater than or equal to 3℃ and less than 5℃, the anti-condensation device is automatically powered off and stopped after running for 75 minutes; and when the temperature difference is greater than or equal to 2℃ and less than 3℃, the anti-condensation device is automatically powered off and stopped after running for 45 minutes.

[0129] In the actual working process, when the air conditioner is in the cooling mode or the dehumidification mode, the temperature sensing bag of the air conditioner obtains the indoor environment dew point temperature, then compares the obtained indoor environment dew point temperature with the preset temperature to obtain a temperature difference, and then compares the obtained temperature difference with the first preset temperature difference, the second preset temperature difference and the third preset temperature difference to obtain a comparison result; when the comparison result is obtained for the first time, whether to detect the air supply mode of the air conditioner is not selected according to the comparison result, but the corresponding interval preset time is selected, and then the comparison is performed again. That is, whether to detect the air supply mode of the air conditioner is selected from the comparison result for the second time. When it is necessary to detect the air supply mode of the air conditioner, whether to close the anti-condensation device is judged according to the temperature difference and the air supply mode of the air conditioner.

[0130] The specific steps of comparing the temperature difference obtained by comparing the indoor environment dew point temperature with the preset temperature with the first preset temperature difference, the second preset temperature difference and the third preset temperature difference are as follows:

[0131] The temperature difference between the indoor environment dew point temperature and the preset temperature is X.

[0132] When X is less than 2℃, the current indoor environment dew point temperature is obtained again after an interval of 90 minutes, the temperature difference is obtained, and if the temperature difference is still less than 2℃, the comparison is performed again after an interval of 90 minutes. If the temperature difference is still less than 2℃ after continuous detection for three times, the anti-condensation device is closed.

[0133] When X is greater than or equal to 2℃, the air supply mode of the air conditioner is obtained, and whether to close the anti-condensation device is selected according to the obtained air supply mode of the air conditioner, specifically as follows:

[0134] When the air conditioner is in the sweep mode, the air conditioner will obtain the current indoor environment dew point temperature again after a preset time interval, and obtain the temperature difference value. If the temperature difference value obtained again is still within the range, the air conditioner will continue to obtain the sweep mode. If the air conditioner is still in the sweep mode, the above operation will be repeated again after a preset time interval. If the temperature difference value obtained each time is greater than or equal to 2℃ for three consecutive times, and the air conditioner is in the sweep mode, the anti-condensation device is turned off.

[0135] When 5℃ < X ≥ 2℃, the air conditioner will obtain the current indoor environment dew point temperature again after 45 minutes. When X ≥ 5℃, the air conditioner will obtain the current indoor environment dew point temperature again after 30 minutes.

[0136] When the air conditioner is in the normal mode, the time when the air conditioner is in the normal mode is obtained, and the running period of the corresponding anti-condensation operation (i.e. the time interval between the movement of the anti-condensation structure from the predetermined position to the next predetermined position) is selected according to the obtained temperature difference value. Specifically:

[0137] When 3℃ < X ≥ 2℃, if the obtained air conditioner normal blowing mode running time is less than 20 minutes, the anti-condensation operation running period is 180 seconds; if the obtained air conditioner normal blowing mode running time is greater than or equal to 20 minutes, the anti-condensation operation running period is 120 seconds. When 5℃ < X ≥ 3℃, if the obtained air conditioner normal blowing mode running time is less than 10 minutes, the anti-condensation operation running period is 120 seconds; if the obtained air conditioner normal blowing mode running time is greater than or equal to 10 minutes and less than 25 minutes, the anti-condensation operation running period is 190 seconds; if the obtained air conditioner normal blowing mode running time is greater than or equal to 25 minutes, the anti-condensation operation running period is 60 seconds.

[0138] When X ≥ 5℃, if the obtained air conditioner normal blowing mode running time is less than 10 minutes, the anti-condensation operation running period is 90 seconds; if the obtained air conditioner normal blowing mode running time is greater than or equal to 10 minutes and less than 20 minutes, the anti-condensation operation running period is 60 seconds; if the obtained air conditioner normal blowing mode running time is greater than or equal to 25 minutes, the anti-condensation operation running period is 30 seconds.

[0139] When X ≥ 5℃, the anti-condensation device will automatically power off and stop moving after 90 minutes of continuous operation. When 5℃ < X ≥ 3℃, the anti-condensation device will automatically power off and stop moving after 75 minutes of continuous operation. When 3℃ < X ≥ 2℃, the anti-condensation device will automatically power off and stop moving after 45 minutes of continuous operation.

[0144] It can be seen that the anti-condensation device provided by the present application can block the edge of the air outlet 20 close to the outside of the air outlet panel 2 by simply arranging the anti-condensation structure 1 and movably arranging the anti-condensation structure 1 between the air outlet frame 3 and the air outlet 20, and arranging one end of the anti-condensation structure 1 outside the air outlet panel 2. At the same time, when the anti-condensation structure 1 is adjusted in the circumferential direction of the air outlet 20 by moving the anti-condensation structure 1 between the air outlet frame 3 and the air outlet 20, different parts of the anti-condensation structure 1 can be arranged to face the air outlet direction of the air outlet frame 3, so that different parts of the anti-condensation structure 1 are uniformly cooled, and the phenomenon of condensation on the air outlet panel 2 is avoided in the case of high air humidity. The phenomenon of condensation on the air outlet panel 2 is optimized in the case of high air humidity, and the phenomenon of condensation dripping or being blown out by the wind is reduced, and the comfort of the user is improved.
