Description

[0002] In order to avoid direct blowing of cold air, the existing air conditioner generally sets a movable volute and a fixed volute, and controls the turning of the movable volute to realize the turning of the air field, so as to ensure the side air outlet in the cooling mode and the air outlet in the heating mode. However, when the above-mentioned scheme is used to switch the air outlet direction, if the movable volute is stuck or does not turn to the position during the movement, the air outlet and the return air will be short-circuited. If the stuck or turning failure of the movable volute cannot be found in time, the heat exchange effect will be greatly affected, and in severe cases, the evaporating temperature will be too low to cause liquid return, the condensing temperature will be too high to cause the compressor load to be too large, thereby reducing the reliability of the compressor and affecting the service life of the air conditioner.

[0003] At present, there is no effective solution to the problem that the existing air conditioner cannot timely and accurately find the stuck or turning failure of the movable volute when switching the air outlet direction, thereby affecting the heat exchange effect and service life of the air conditioner.

[0016] If the actual evaporator temperature is greater than or equal to the target evaporator temperature, it is determined that the movable volute is rotated to the position.

[0017] Further, in the heating mode, judging whether the movable volute is rotated to the position according to the comparison result and the judgment strategy corresponding to the running mode comprises:

[0058] Embodiment 1

[0059] Some existing air conditioners are provided with movable and fixed volutes to avoid direct blowing of cold air, Figure 1 Fig. 1 is a schematic diagram of the direction of return air and outlet air of an existing air conditioner in a cooling mode, as shown, in the cooling mode, the side outlet port blows air, and the lower outlet port returns air, Figure 1 Fig. 2 is a schematic diagram of the direction of return air and outlet air of the existing air conditioner in a heating mode, as shown, in the heating mode, the lower outlet port blows air, and the side outlet port returns air. Figure 2 Fig. 2 is a schematic diagram of the direction of return air and outlet air of the existing air conditioner in a heating mode, as shown, in the heating mode, the lower outlet port blows air, and the side outlet port returns air. Figure 2 Fig. 2 is a schematic diagram of the direction of return air and outlet air of the existing air conditioner in a heating mode, as shown, in the heating mode, the lower outlet port blows air, and the side outlet port returns air.

[0060] To solve the problem that the existing air conditioner cannot timely and accurately find that the movable volute is stuck or not rotated to the position during switching of the direction of outlet air, thereby affecting the heat exchange effect and service life of the air conditioner, the embodiment provides a volute position detection method applied to an air conditioner, the air conditioner comprising a movable volute and a fixed volute, when the movable volute is rotated to a first position, the side outlet port of the air conditioner blows air, when the movable volute is rotated to a second position, the lower outlet port of the air conditioner blows air, Figure 3 Fig. 3 is a flowchart of the volute position detection method according to the embodiment of the application, as shown, the method comprises the following steps: Figure 3

[0061] S101, determining a target evaporator temperature according to the operating mode of the air conditioner, the indoor environment temperature and the outdoor environment temperature; wherein a corresponding relationship between the target evaporator temperature and the indoor environment temperature and the outdoor environment temperature in different operating modes is preset.

[0062] The operating mode comprises a cooling mode and a heating mode.

[0063] S102, judging whether the movable volute is rotated to the position according to the operating mode, the actual evaporator temperature and the target evaporator temperature.

[0064] ​The volute position detection method of the embodiment determines the corresponding target evaporator temperature according to the operation mode of the air conditioner, the indoor environment temperature and the outdoor environment temperature, that is, the temperature that the evaporator should reach. In different operation modes, as long as the indoor environment temperature and the outdoor environment temperature are determined, the temperature that the evaporator can reach after the air conditioner runs for a preset time length is determined. Whether the actual evaporator temperature reaches the target evaporator temperature is judged to determine whether the movable volute is rotated in place. The movable volute not being rotated in place can be detected in a timely and accurate manner, thereby avoiding affecting the heat exchange effect and service life of the air conditioner.

[0065] In the case of the same indoor environment temperature, the evaporator temperature is different when the indoor environment temperature is different. In the case of the same outdoor environment temperature, the evaporator temperature is also different when the indoor environment temperature is different. Therefore, the target evaporator temperature needs to be determined according to the indoor environment temperature and the outdoor environment temperature.

[0066] Therefore, the corresponding relationship between the target evaporator temperature and the indoor environment temperature and the outdoor environment temperature in different operation modes is preset, including: in the cooling mode, detecting the evaporator temperature after the air conditioner runs for a preset time length under the same indoor environment temperature and different outdoor environment temperatures, and under the same outdoor environment temperature and different indoor environment temperatures, thereby obtaining the corresponding relationship between the target evaporator temperature and the indoor environment temperature and the outdoor environment temperature in the cooling mode.

[0067] The corresponding relationship between the target evaporator temperature and the indoor environment temperature and the outdoor environment temperature in the cooling mode is shown in Table 1 below, wherein the outer ring is the outdoor environment temperature and the inner ring is the indoor environment temperature.

[0068]

[0069] As shown in Table 1, in the cooling mode, the unique target evaporator temperature A1, B1, C1, D1... can be determined through the outdoor environment temperature and the indoor environment temperature.

[0070] In the heating mode, the evaporator temperature after the air conditioner runs for a preset time length under the same indoor environment temperature and different outdoor environment temperatures, and under the same outdoor environment temperature and different indoor environment temperatures is detected, thereby obtaining the corresponding relationship between the target evaporator temperature and the indoor environment temperature and the outdoor environment temperature in the heating mode.

[0071] The corresponding relationship between the target evaporator temperature and the indoor environment temperature and the outdoor environment temperature in the heating mode is shown in Table 2 below:

[0072]

[0073] As shown in Table 2, in the heating mode, the unique target evaporator temperature A2, B2, C2, D2... can be determined by the outdoor ambient temperature and the indoor ambient temperature.

[0074] Since the air conditioner enters the cooling mode or the heating mode, and the volute is timely rotated to the position, the evaporator temperature will not immediately reach the target evaporator temperature, and needs to run for a period of time, therefore, according to the running mode, the actual evaporator temperature and the target evaporator temperature, whether the volute is rotated to the position is judged, including: after the air conditioner runs for a preset time length, comparing the actual evaporator temperature and the target evaporator temperature; according to the comparison result and the judgment strategy corresponding to the running mode, whether the volute is rotated to the position is judged.

[0075] In different running modes, the target evaporator temperature and the judgment strategy are different, Figure 4 The position diagram of the volute not rotated to the position in the cooling mode is shown in Figure 4 As shown in Table 2, in the heating mode, the unique target evaporator temperature A2, B2, C2, D2... can be determined by the outdoor ambient temperature and the indoor ambient temperature.

[0076] Specifically, in the cooling mode, according to the comparison result of the actual evaporator temperature and the target evaporator temperature and the judgment strategy corresponding to the current running mode, whether the volute is rotated to the position is judged, including: if the actual evaporator temperature is less than the target evaporator temperature, it is indicated that there is a wind leakage condition, and it is determined that the volute is not rotated to the position; if the actual evaporator temperature is greater than or equal to the target evaporator temperature, it is indicated that there is no wind leakage condition, and it is determined that the volute is rotated to the position.

[0077] If the volute is not rotated to the position, it may be due to the volute being stuck, at this time, it can be solved by resetting the volute and then rotating it again, therefore, after it is determined that the volute is not rotated to the position in the cooling mode, the above method further includes: controlling the volute to reset, and then controlling the volute to rotate again; after a preset time length, judging whether the actual evaporator temperature is greater than or equal to the target evaporator temperature; if yes, it is determined that the volute is rotated to the position; if no, it is indicated that the volute is stuck and cannot be solved by resetting to rotate to the position, at this time, in order to avoid affecting the heat exchange effect or the service life of the air conditioner, a fault should be reported and the air conditioner should be controlled to stop.

[0078] Figure 5 This is a schematic diagram showing the position of the moving volute in heating mode when it has not rotated to its final position. Figure 5 As shown, failure to rotate the volute properly will cause air leakage, resulting in insufficient airflow through the evaporator, poor refrigerant condensation, and excessively high evaporator pipe temperature. Therefore, in cooling mode, the system determines whether the moving volute has rotated properly based on a comparison between the actual evaporator temperature and the target evaporator temperature, as well as the judgment strategy corresponding to the current operating mode. This includes: if the actual evaporator temperature is greater than the target evaporator temperature, it indicates air leakage, and the moving volute is determined not to have rotated properly; if the actual evaporator temperature is less than or equal to the target evaporator temperature, it indicates no air leakage, and the moving volute is determined to have rotated properly.

[0079] If the moving volute does not rotate to its proper position, it may be due to the moving volute being stuck. In this case, it can be resolved by resetting the moving volute and then rotating it again. Therefore, in heating mode, after determining that the moving volute has not rotated to its proper position, the above method also includes: controlling the moving volute to reset, and then controlling the moving volute to rotate again; after a preset time, determining whether the actual evaporator temperature is less than or equal to the target evaporator temperature; if yes, then the moving volute is determined to have rotated to its proper position; if no, the moving volute is stuck and the problem of not rotating to the proper position cannot be resolved by resetting. In this case, to avoid affecting the heat exchange effect or the life of the air conditioner, the fault should be reported and the air conditioner should be shut down.

[0080] In cooling or heating mode, if the evaporator temperature does not reach the target evaporator temperature, it may be due to the compressor frequency being too low. Therefore, in order to eliminate the influence of the compressor frequency, improve the accuracy of the moving volute position detection, and avoid misjudgment, before determining whether the moving volute has rotated to the correct position based on the operating mode, actual evaporator temperature, and target evaporator temperature, the above method also includes: controlling the compressor frequency of the air conditioner to increase to the upper limit of the current operating mode.

[0081] Example 2

[0082] This embodiment provides another method for detecting the position of the volute. Figure 6 The flowchart of the volute position detection method according to an embodiment of the present invention is as follows: Figure 6 As shown, the volute position detection method includes:

[0083] S1 controls the air conditioner to turn on.

[0084] S2, determine whether the current mode is cooling or heating; if it is cooling mode, proceed to step S3, if it is heating mode, proceed to step S10.

[0085] S3 controls the volute to first perform the side air outlet rotation action, while the compressor runs to the frequency limit of the current mode.

[0086] S4, selecting a target evaporator temperature according to the current indoor environment temperature and the outdoor environment temperature.

[0087] S5, after the air conditioner runs for a preset time T, judging the relationship between the actual evaporator temperature t and the target evaporator temperature t0, if t≥t0, executing step S6, if t

[0088] S6, judging that the movable volute is rotated to the position.

[0089] S7, judging that the movable volute is not rotated to the position, controlling the movable volute to reset, then executing the side-out air rotation action again, and then executing step S8.

[0090] S8, judging the relationship between the actual evaporator temperature t and the target evaporator temperature t0, if t≥t0, executing step S6, if t

[0091] S9, judging that the volute rotation mechanism is stuck, controlling the air conditioner to stop and report a fault.

[0092] After the air conditioner runs for a preset time T, if t

[0093] S10, controlling the movable volute to execute the down-out air rotation action first, and controlling the compressor to run to the upper limit of the frequency of the current mode.

[0094] S11, selecting a target evaporator temperature according to the current indoor environment temperature and the outdoor environment temperature.

[0095] S12, after the air conditioner runs for a preset time T, judging the relationship between the actual evaporator temperature t and the target evaporator temperature t0, if t≤t0, executing step S13, if t

[0096] S13, judging that the movable volute is rotated to the position.

[0097] S14, judging that the movable volute is not rotated to the position, controlling the movable volute to reset, then executing the side-out air rotation action again, and then executing step S15.

[0098] S15, judging the relationship between the actual evaporator temperature t and the target evaporator temperature t0, if t≤t0, executing step S13, if t

[0099] S16 indicates that the volute rotating mechanism is stuck, and the air conditioner is shut down and a fault is reported.

[0100] After the air conditioner has been running for a preset time T, if t > t0, it is assumed that the moving volute has not rotated to its proper position, causing air leakage. This results in insufficient airflow through the evaporator, leading to poor refrigerant condensation and high evaporator pipe temperature. The moving volute needs to perform the downward airflow rotation action again for further evaluation. If t ≤ t0, it is assumed that the volute has rotated to its proper position, and the air conditioner enters normal cooling mode. If t > t0, it is assumed that the volute rotation mechanism is stuck, and the air conditioner is shut down and a fault is reported.

[0101] Example 3

[0102] This embodiment provides a volute position detection device. Figure 7 This is a structural block diagram of a volute position detection device according to an embodiment of the present invention, such as... Figure 7 As shown, the device includes:

[0103] The determination module 10 is used to determine the target evaporator temperature based on the air conditioner's operating mode, indoor ambient temperature, and outdoor ambient temperature; wherein, a preset correspondence between the target evaporator temperature and the indoor ambient temperature and outdoor ambient temperature is provided for different operating modes.

[0104] The judgment module 20 is used to determine whether the moving volute has rotated into place based on the operating mode, the actual evaporator temperature, and the target evaporator temperature.

[0105] The volute position detection device in this embodiment determines the corresponding target evaporator temperature, i.e., the temperature that the evaporator should reach, based on the air conditioner's operating mode, indoor ambient temperature, and outdoor ambient temperature. Under different operating modes, as long as the indoor and outdoor ambient temperatures are determined, the evaporator will reach the set temperature after the air conditioner has been running for a preset time. The device determines whether the moving volute has rotated to the correct position based on whether the actual evaporator temperature has reached the target evaporator temperature. This allows for timely and accurate detection of situations where the moving volute has not rotated to the correct position, thus avoiding impacting the air conditioner's heat exchange effect and service life.

[0106] When the indoor ambient temperature is the same, the evaporator temperature will be different depending on the outdoor ambient temperature to achieve the same target indoor temperature. Similarly, when the outdoor ambient temperature is the same, the evaporator temperature will also be different depending on the indoor ambient temperature to achieve the same target indoor temperature. Therefore, it is necessary to determine the target evaporator temperature based on both the indoor and outdoor ambient temperatures.

[0107] Therefore, the pre-defined relationships between the target evaporator temperature and the indoor and outdoor ambient temperatures are established for different operating modes, including:

[0108] In the cooling mode, the evaporator temperature after the air conditioner runs for a preset time length under the same indoor environment temperature and different outdoor environment temperatures, and the evaporator temperature after the air conditioner runs for a preset time length under the same outdoor environment temperature and different indoor environment temperatures are detected, so as to obtain the corresponding relationship between the target evaporator temperature and the indoor environment temperature and the outdoor environment temperature in the cooling mode.

[0109] In the heating mode, the evaporator temperature after the air conditioner runs for a preset time length under the same indoor environment temperature and different outdoor environment temperatures, and the evaporator temperature after the air conditioner runs for a preset time length under the same outdoor environment temperature and different indoor environment temperatures are detected, so as to obtain the corresponding relationship between the target evaporator temperature and the indoor environment temperature and the outdoor environment temperature in the heating mode.

[0110] Since the evaporator temperature will not immediately reach the target evaporator temperature after the air conditioner enters the cooling mode or the heating mode and the movable volute is timely rotated to the position, the air conditioner needs to run for a period of time, and when the judging module 20 judges whether the movable volute is rotated to the position according to the running mode, the actual evaporator temperature and the target evaporator temperature, the specific operation is that: after the air conditioner runs for a preset time length, the actual evaporator temperature and the target evaporator temperature are compared; according to the comparison result and the judgment strategy corresponding to the running mode, whether the movable volute is rotated to the position is judged.

[0111] The target evaporator temperature and the judgment strategy are different in different running modes, as shown in the above-mentioned Figure 4 If the movable volute is not rotated to the position, wind leakage will occur, the air volume passing through the evaporator is too low to cause incomplete evaporation of the system refrigerant, and the evaporator temperature is lower than the target evaporator temperature, so in the cooling mode, the judging module 20 is specifically configured to: when the actual evaporator temperature is less than the target evaporator temperature, indicating that there is wind leakage, it is determined that the movable volute is not rotated to the position; and when the actual evaporator temperature is greater than or equal to the target evaporator temperature, indicating that there is no wind leakage, it is determined that the movable volute is rotated to the position.

[0112] Figure 8 For the structure block diagram of the volute position detection device according to another embodiment of the present application, if the movable volute is not rotated to the position, it may be caused by the fact that the movable volute is stuck, at this time, the problem can be solved by resetting the movable volute and then rotating it again, so as shown in Figure 8As shown in the above, the device further comprises a control module 30, configured to, in the refrigeration mode, control the movable volute to reset when the judging module 20 judges that the movable volute is not rotated to the position, and then control the movable volute to rotate again; after a preset time length, the judging module 20 judges again whether the actual evaporator temperature is greater than or equal to the target evaporator temperature; if yes, it is judged that the movable volute is rotated to the position; if no, it is indicated that the movable volute is stuck and cannot solve the problem of not being rotated to the position by resetting, at this time, in order to avoid affecting the heat exchange effect or the service life of the air conditioner, the fault should be reported and the air conditioner should be controlled to stop running.

[0113] As mentioned above Figure 5 As shown in the above, the device further comprises a control module 30, configured to, in the refrigeration mode, control the movable volute to reset when the judging module 20 judges that the movable volute is not rotated to the position, and then control the movable volute to rotate again; after a preset time length, the judging module 20 judges again whether the actual evaporator temperature is greater than or equal to the target evaporator temperature; if yes, it is judged that the movable volute is rotated to the position; if no, it is indicated that the movable volute is stuck and cannot solve the problem of not being rotated to the position by resetting, at this time, in order to avoid affecting the heat exchange effect or the service life of the air conditioner, the fault should be reported and the air conditioner should be controlled to stop running.

[0114] If the movable volute is not rotated to the position, it may be due to the fact that the movable volute is stuck, at this time, the problem can be solved by resetting the movable volute and then rotating it again, therefore, the control module 30 is further configured to, in the heating mode, control the movable volute to reset when the judging module 20 judges that the movable volute is not rotated to the position, and then control the movable volute to rotate again; after a preset time length, the judging module 20 judges again whether the actual evaporator temperature is less than or equal to the target evaporator temperature; if yes, it is judged that the movable volute is rotated to the position; if no, the movable volute is stuck and cannot solve the problem of not being rotated to the position by resetting, at this time, in order to avoid affecting the heat exchange effect or the service life of the air conditioner, the fault should be reported and the air conditioner should be controlled to stop running.
