Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning devices, in particular to an air conditioner and a control method thereof. BACKGROUND

[0002] The existing air conditioner indoor unit generally has an auxiliary heating function, that is, an electric heating device is arranged in the air conditioner indoor unit to assist heating and enhance the air conditioning heating effect.

[0003] Generally, the electric heating device is arranged near the evaporator of the indoor unit. For example, the electric heating device of a ceiling-mounted air conditioner indoor unit is generally installed between the evaporator and the cross-flow fan. When the air conditioner is running in cooling mode, indoor air passes through the air inlet of the air conditioner indoor unit, is cooled by the evaporator, and becomes cold air. A part of the cold air passes through the electric heating device and is blown out of the air outlet along with the cross-flow fan. Therefore, when the air conditioner is running in cooling mode, the temperature of the electric heating device decreases rapidly. At the same time, due to the cooling of the air conditioner, a lot of condensed water is condensed on the fins of the evaporator. In actual tests after the air conditioner is turned off after cooling, the humidity of the air in the air duct is very high. Therefore, the electric heating device will produce condensed water on the surface after the air conditioner is turned off. When the air conditioner is used in summer, the air conditioner is frequently turned on for cooling, which can cause more and more condensed water on the electric heating device. When the air speed of the air conditioner is high, the condensed water on the electric heating device can be blown out directly and fall into the indoor space, affecting the user's experience of using the air conditioner. At the same time, the long-term presence of condensed water on the electric heating device poses a certain safety hazard, which can cause oxidation and rust of the metal parts of the electric heating device, shorten its service life, and easily cause the electric heating device to be in a humid state for a long time, resulting in mold growth and causing the air blown out by the air conditioner to have a moldy smell.

[0004] In addition, according to actual experimental verification, when the air conditioner is running in cooling mode, due to the uneven temperature field around the electric heating device and the high humidity inside, the electric heating device will also continuously produce condensed water during the operation of the air conditioner, which will directly drip after a period of accumulation.

[0005] To solve the above technical problems, the existing solutions are as follows:

[0006] 1. After the air conditioner ends cooling, the air conditioner enters the air supply mode within a short period of time, which can increase the temperature of the electric heating device and reduce the possibility of condensed water on the electric heating device. However, the temperature of the electric heating device cannot be increased to completely avoid the problem of condensed water on the electric heating device.

[0007] 2. When the air conditioner is in refrigeration operation, the air conditioner is controlled to be turned off by a remote controller / voice control / APP, etc. The air fan and compressor of the air conditioner are controlled to be turned off according to a program. After the air deflector of the indoor unit is turned off, the indoor air fan is operated at a low speed according to a set speed, and the electric heating device is turned on for a short time to make the temperature of the electric heating device rise and evaporate the condensed water on the electric heating device. After the refrigeration is completed, the electric heating device is turned on to heat and evaporate the condensed water. However, the problem of excessive condensed water accumulated and dropped from the air conditioner during long-term refrigeration operation cannot be avoided.

[0008] The above information disclosed in the background section of this specification is only for the purpose of enhancing the understanding of the background of the present application and therefore, it can include matters known by those skilled in the art. SUMMARY

[0059] The preferred embodiments of the present application will be described hereinafter with reference to the accompanying drawings. It will be understood by those skilled in the art that these embodiments are merely intended to explain the technical principles of the present application, and are not intended to limit the scope of protection of the present application.

[0060] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0061] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0062] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0063] like Figures 1-3 As shown, the air conditioner includes an evaporator 1, an electric heating device 2, and a cross-flow fan 3 arranged sequentially in the airflow direction inside the casing.

[0064] exist Figure 1 As shown, during the cooling or dehumidifying operation of the air conditioner, the temperatures of the space above, below, to the left, and to the right of the electric heating device 2 are not consistent. When the detected temperatures in the two areas surrounding the electric heating device are as follows: the lower temperature is lower than the dew point temperature of the higher temperature, condensation will occur between the two temperature zones, i.e., condensate will form on the electric heating device. During air conditioner operation, the electric heating device continuously produces condensate, which accumulates over time and drips directly, then is blown out by the cross-flow fan.

[0065] When an air conditioner is running, different operating states, such as fan speed, air deflector position, and compressor operating frequency (determined by ambient temperature and user-set temperature), result in inconsistent temperature distribution around the electric heating device even when the device is at the same angle.

[0066] The angle of the electric heating device is important to the even distribution of the temperature field around the electric heating device when the air conditioner is in the cooling or dehumidifying mode. If the electric heating device is in an angle that makes the temperature field around the electric heating device uneven, condensation is likely to occur on the electric heating device. If the electric heating device is in an angle that makes the temperature field around the electric heating device even, condensation is avoided or reduced on the electric heating device. Therefore, how to determine the anti-condensation position of the electric heating device so that the parameters around the electric heating device do not meet the condensation condition is the object of the present application.

[0067] The air conditioner comprises an electric heating device 2 and an electric heating driving device 5 for driving the electric heating device 2 to rotate so as to adjust the angle of the electric heating device 2.

[0068] The electric heating device 2 of the air conditioner is driven to rotate by the electric heating driving device 5. The electric heating device 2 is generally rotatably mounted on a mounting bracket or a tube plate of the evaporator 1. The electric heating driving device 5 comprises a driving motor, for example, a stepping motor, which drives the electric heating device 2 to rotate. The driving motor can directly drive the electric heating device 2 or drive the electric heating device 2 through a gear.

[0069] The electric heating driving device 5 generally drives the electric heating device 2 to alternately rotate in the positive direction and the reverse direction in the rotation range. That is, the electric heating driving device 2 drives the electric heating device 2 to rotate in the positive direction from the initial angle to the terminal angle, which is one rotation of the electric heating device in the rotation range. The electric heating driving device 2 drives the electric heating device 2 to rotate in the reverse direction from the terminal angle to the initial angle, which is one rotation of the electric heating device in the rotation range. This mode can avoid the winding of the electric heating wire.

[0070] The air conditioner comprises a detection module 4 and a detection module driving device 6. The detection module 4 is arranged around the electric heating device 2. The detection module driving device 6 is used to drive the detection module 4 to rotate around the electric heating device 5.

[0071] The detection module 4 is at a certain distance from the electric heating device 2 and is used to detect the parameters around the electric heating device 2.

[0072] In some embodiments, the detection module 4 is generally mounted on a bracket 41. The bracket 41 can be arranged in a circular ring shape. The bracket 41 is provided with a circular ring-shaped sliding groove and a slide rail 42 sliding along the sliding groove. The detection module 4 is located on the slide rail 42, and the slide rail 42 has a rack. The detection module driving device 6 comprises a driving motor, for example, a stepping motor, which is mounted on the bracket 41. The driving motor drives the slide rail 42 to slide through the gear cooperating with the rack.

[0073] The detection module driving device 6 drives the detection module 4 to rotate forward and reverse alternately in a rotation range, that is, the detection module driving device 6 drives the detection module 4 to rotate forward from an initial angle to a terminal angle, which is one rotation of the detection module in the rotation range, and the detection module driving device 6 drives the detection module 4 to rotate reverse from the terminal angle to the initial angle, which is one rotation of the detection module in the rotation range. In this way, the winding of the detection module wire can be avoided.

[0074] In order to reduce the cost, the detection module 4 is only provided with one, and the purpose of the present application can also be achieved.

[0075] When the air conditioner is in cooling or dehumidifying operation, the electric heating device is stationary, the detection module driving device drives the detection module to rotate around the electric heating device, and the detection module detects whether the temperature field around the electric heating device is uniform. When the temperature field is within the set deviation range, the risk of condensation is small, and when the temperature field exceeds the set deviation range, the risk of condensation is large. The electric heating device is driven to rotate by the electric heating driving device to rotate by a set angle. The goal is to find a suitable electric heating position to make the temperature field around the electric heating device uniform, avoid or reduce the alternating mixing of cold and hot air around the electric heating device, and cause condensation water and dripping.

[0076] The following will be described through specific embodiments:

[0077] Embodiment one

[0078] The air conditioner comprises an electric heating device, an electric heating driving device, a detection module, a detection module driving device and a control module.

[0079] The electric heating driving device is used to drive the electric heating device to rotate.

[0080] The detection module is located around the electric heating device and is used to detect the parameters around the electric heating device.

[0081] The detection module driving device is used to drive the detection module to rotate around the electric heating device.

[0082] The control module is used to detect the condensation condition when the air conditioner is in cooling or dehumidifying operation, control the detection module driving device to drive the detection module to rotate around the electric heating device, and obtain at least two parameters detected by the detection module during rotation.

[0083] Preferably, the detection module detects the parameters in real time, and a parameter curve can be formed to improve the accuracy of temperature distribution detection.

[0084] The control module is used for entering the condensation condition judgment after the condensation condition detection is completed: judging whether the electric heating device condensation condition is met according to the parameters detected by the detection module, controlling the electric heating driving device to drive the electric heating device to rotate a set angle and maintain at the angle for a set time, and then entering the condensation condition detection; judging whether the electric heating device condensation condition is not met according to the parameters detected by the detection module, and controlling the electric heating device to be stationary.

[0085] The embodiment first performs the condensation condition detection: controlling the detection module driving device to drive the detection module to rotate around the electric heating device, and detecting at least two parameters during the rotation of the detection module. The rotation of the detection module can be continuous rotation or angle-fixed rotation.

[0086] In the continuous rotation embodiment, the detection module driving device drives the detection module to continuously rotate around the electric heating device, and the detection module detects the parameters in real time.

[0087] In the angle-fixed rotation embodiment, the detection module driving device drives the detection module to rotate to a plurality of different positions around the electric heating device, and the detection module detects the parameters at the corresponding positions.

[0088] The control module performs the condensation condition judgment after the condensation condition detection is completed: judging whether the electric heating device condensation condition is met according to the parameters detected by the detection module, wherein the electric heating device condensation condition is mainly embodied by whether the temperature field distribution around the electric heating device is uniform, when the temperature field distribution is uniform, i.e. according to the parameters detected by the detection module, it is judged that the electric heating device condensation condition is not met, the electric heating device is controlled to be stationary; when the temperature field distribution is not uniform, i.e. according to the parameters detected by the detection module, it is judged that the electric heating device condensation condition is met, the electric heating driving device is controlled to drive the electric heating device to rotate a set angle and maintain at the angle for a set time, and then the condensation condition detection is entered, until a condensation prevention position is found to make the temperature field distribution around the electric heating device uniform. The condensation prevention position found in the embodiment can ensure that the temperature field distribution around the electric heating device is uniform, and avoid or reduce the condensation of the electric heating device.

[0089] The control method of the air conditioner is as follows:

[0090] When the air conditioner is in refrigeration or dehumidification operation;

[0091] The condensation condition detection step: the detection module driving device drives the detection module to rotate around the electric heating device, and at least two parameters detected by the detection module during the rotation are obtained;

[0092] Condensation condition judging step: when the parameters detected by the detection module meet the condensation condition of the electric heating device, the electric heating driving device drives the electric heating device to rotate a set angle and maintain at the angle for a set time, and then the condensation condition detecting step is entered; when the parameters detected by the detection module do not meet the condensation condition of the electric heating device, the electric heating device is not moved.

[0093] In the refrigeration or dehumidification operation of the air conditioner, the detection module detects at least two parameters in the rotating process, and whether the condensation condition of the electric heating device is met is judged according to the parameters detected by the detection module. When the parameters detected by the detection module meet the condensation condition of the electric heating device, there is a risk of condensation, and the angle of the electric heating device needs to be adjusted. The electric heating driving device drives the electric heating device to rotate a set angle and maintain at the angle for a set time, and then the step of detecting the parameters by the detection module is continued. When the parameters detected by the detection module do not meet the condensation condition of the electric heating device, there is no risk of condensation, and the electric heating device is not moved.

[0094] As shown in FIG. 1, the control method of the air conditioner of the embodiment is as follows: Figure 4

[0095] S1, the air conditioner is in refrigeration or dehumidification operation.

[0096] S2, the detection module driving device drives the detection module to rotate around the electric heating device, and at least two parameters detected by the detection module in the rotating process are obtained.

[0097] S3, whether the condensation condition of the electric heating device is met is judged according to the parameters detected by the detection module. When the condensation condition of the electric heating device is met, step S4 is entered, otherwise, step S5 is entered.

[0098] S4, the electric heating driving device drives the electric heating device to rotate a set angle and maintain at the angle for a set time, and step S2 is entered.

[0099] S5, the electric heating device is not moved, and the air conditioner continues to operate according to the set state.

[0100] In step S5, when the electric heating device is at an angle, the temperature field distribution around the electric heating device is uniform, which will not cause the electric heating device to condense. Therefore, the electric heating device is not moved, and the air conditioner continues to operate according to the set state.

[0101] In some embodiments, in order to avoid the running time of the air conditioner changing the temperature field around the electric heating device, thereby changing the condensation state of the electric heating device, in step S5, after the air conditioner continues to operate according to the set state for a period of time, it can also re-enter step S2 for a condensation judgment, or in step S5, it can enter step S2 for condensation judgment at a fixed time.

[0102] Embodiment two ​

[0103] The air conditioner comprises an electric heating device, an electric heating driving device, a detection module, a detection module driving device and a control module.

[0104] The detection module 4 comprises a temperature sensor located around the electric heating device.

[0105] Specifically, the detection module 4 comprises a temperature sensor arranged around the electric heating device, which is at a certain distance from the electric heating device and is used to measure the air temperature around the electric heating device.

[0106] The control module is used to perform condensation condition detection when the air conditioner is in cooling or dehumidifying operation, to control the detection module driving device to drive the temperature sensor to rotate around the electric heating device, and to obtain at least two temperatures detected by the temperature sensor during rotation.

[0107] After the condensation condition detection is completed, the control module is used to enter condensation condition judgment, to determine the maximum temperature Tmax and the minimum temperature Tmin according to the temperatures detected by the temperature sensor, to control the electric heating driving device to drive the electric heating device to rotate by a set angle and maintain at the angle for a set time when the difference between the maximum temperature Tmax and the minimum temperature Tmin is higher than a set temperature, and to control the electric heating device to be stationary when the difference between the maximum temperature Tmax and the minimum temperature Tmin is lower than the set temperature.

[0108] The present embodiment first performs condensation condition detection, controls the detection module driving device to drive the temperature sensor to rotate around the electric heating device, and the temperature sensor detects at least two temperatures during rotation.

[0109] In some embodiments, the detection module driving device drives the temperature sensor to continuously rotate around the electric heating device, and the temperature sensor detects the temperature in real time.

[0110] In some embodiments, the detection module driving device drives the temperature sensor to rotate to a plurality of different positions around the electric heating device, and the temperature sensor detects the temperature at the corresponding position when at the plurality of different positions.

[0111] The control module judges the condensation condition after the detection of the condensation condition is completed: whether the temperature detected by the temperature sensor meets the condensation condition of the electric heating device, wherein the condensation condition of the electric heating device is mainly reflected by whether the temperature field distribution around the electric heating device is uniform, and when the temperature field distribution is uniform, i.e., when it is determined according to the temperature detected by the temperature sensor that the condensation condition of the electric heating device is not met, the electric heating device is not controlled to move; when the temperature field distribution is not uniform, i.e., when it is determined according to the temperature detected by the temperature sensor that the condensation condition of the electric heating device is met, the electric heating driving device is controlled to drive the electric heating device to rotate by a set angle and maintain at the angle for a set time, and then the detection of the condensation condition is entered again until a condensation-preventing position is found, so that the temperature field distribution around the electric heating device is uniform. The condensation-preventing position found in the embodiment can ensure that the temperature field distribution around the electric heating device is uniform, thereby avoiding or reducing the condensation of the electric heating device.

[0112] Specifically, the maximum temperature Tmax and the minimum temperature Tmin are determined according to the temperature detected by the temperature sensor; when the difference between the maximum temperature Tmax and the minimum temperature Tmin is higher than a set temperature, it indicates that the temperature field distribution is not uniform, and the electric heating driving device is controlled to drive the electric heating device to rotate by a set angle and maintain at the angle for a set time, and then the detection of the condensation condition is entered again; when the difference between the maximum temperature Tmax and the minimum temperature Tmin is lower than the set temperature, it indicates that the temperature field distribution is uniform, and the electric heating device is not controlled to move.

[0113] The control method of the air conditioner is as follows:

[0114] The air conditioner is operated in a refrigeration or dehumidification mode;

[0115] The detection of the condensation condition: the detection module drives the temperature sensor to rotate around the electric heating device, and at least two temperatures detected by the temperature sensor during the rotation are obtained;

When a plurality of set angles are changed and no electric heating device angle that does not meet the condensation condition of the electric heating device 2 is found, the electric heating device is rotated to the angle of the electric heating device corresponding to the minimum value of the difference between the maximum temperature Tmax and the minimum temperature Tmin, so as to minimize the generation of condensed water.

[0127] S6, the electric heating device is stationary, and the air conditioner continues to operate according to the set state.

[0128] In step S6, when the angle of the electric heating device is explained, the temperature field around the electric heating device is uniform, which will not cause condensation of the electric heating device. Therefore, the electric heating device is stationary, and the air conditioner continues to operate according to the set state.

[0129] In some embodiments, in order to avoid the running time of the air conditioner changing the temperature field around the electric heating device, thereby changing the condensation state of the electric heating device, in step S6, after the air conditioner continues to operate according to the set state for a period of time, it can also re-enter step S2 to make a condensation determination, or in step S6, it can enter step S2 for condensation determination at a certain time.

[0130] The embodiment increases the electric heating device driving device of the electric heating device, so that the electric heating device can adjust the angle according to the system setting during the actual operation of the air conditioner. Cooperate with the temperature sensor arranged around the electric heating device to monitor whether the temperature field around the electric heating device is uniform. When the temperature field reaches the set deviation range, the electric heating device is stationary at a fixed angle. When the temperature field exceeds the set deviation range, the electric heating device is rotated until the position of the electric heating device makes the temperature field around it uniform.

[0142] The humidity sensor detects the humidity S.

[0143] The control module judges the condensation condition after the detection of the condensation condition is completed: whether the condensation condition of the electric heating device is met is judged according to the temperature detected by the temperature sensor and the humidity detected by the humidity sensor, wherein the condensation condition of the electric heating device is mainly embodied by whether the temperature field distribution around the electric heating device is uniform, when the temperature field distribution is uniform, that is, when it is judged according to the temperature detected by the temperature sensor and the humidity detected by the humidity sensor that the condensation condition of the electric heating device is not met, the electric heating device is not controlled to move; when the temperature field distribution is not uniform, that is, when it is judged according to the temperature detected by the temperature sensor and the humidity detected by the humidity sensor that the condensation condition of the electric heating device is met, the electric heating driving device is controlled to drive the electric heating device to rotate by a set angle and maintain at the angle for a set time, and then the detection of the condensation condition is entered again until a condensation-preventing position is found so that the temperature field distribution around the electric heating device is uniform. The condensation-preventing position found in the embodiment can ensure that the temperature field distribution around the electric heating device is uniform, thereby avoiding or reducing the condensation of the electric heating device.

[0145] The control method of the air conditioner is as follows:

[0146] The air conditioner is operated in refrigeration or dehumidification;

[0147] The detection of the condensation condition: the detection module drives the temperature sensor to rotate around the electric heating device to obtain at least two temperatures detected by the temperature sensor during the rotation; the humidity S detected by the humidity sensor is obtained;

When the dew point temperature K is higher than the minimum temperature Tmin, there is a risk of condensation, the angle of the electric heating device 2 needs to be adjusted, the electric heating driving device 5 drives the electric heating device 2 to rotate to a set angle and maintain at the angle for a set time, the windward angle of the electric heating device is adjusted, and then the temperature sensor continues to detect the temperature. When the dew point temperature K is lower than the minimum temperature Tmin, the temperature around the electric heating device tends to be uniform, there is no risk of condensation, the electric heating device is stationary, and the air conditioner can continue to operate according to the set state. Otherwise, the electric heating device is rotated in the above-mentioned manner, the windward angle of the electric heating device is adjusted and the temperature and humidity are detected until the electric heating device is rotated to an angle at which the dew point temperature K is lower than the minimum temperature Tmin, and there is no risk of condensation.

[0159] In step S6, when the angle of the electric heating device is explained, the temperature field distribution around the electric heating device is uniform, which will not cause condensation of the electric heating device. Therefore, the electric heating device is stationary, and the air conditioner continues to run according to the set state.

[0160] In some embodiments, in order to avoid the running time of the air conditioner changing the temperature field around the electric heating device, thereby changing the condensation state of the electric heating device, in step S6, after the air conditioner continues to run according to the set state for a period of time, it can also enter step S2 again to make a condensation judgment, or in step S6, it can enter step S2 to make a condensation judgment at a certain time.

[0161] The embodiment increases the electric heating device driving device of the electric heating device, so that the electric heating device can adjust the angle according to the system setting during the actual operation of the air conditioner. Cooperate with the temperature sensor and humidity sensor arranged around the electric heating, monitor whether the temperature field around the electric heating device is uniform.

[0162] Embodiment four

[0163] On the basis of embodiments one to three, the control module of the present embodiment is used to judge whether the running parameters of the air conditioner change when the electric heating device is stationary, and is used to control the air conditioner to run according to the changed running parameters for a set time before entering the condensation condition detection when the running parameters of the air conditioner change.

[0164] The control method is: when the electric heating device is stationary, judge whether the running parameters of the air conditioner change, and when the running parameters of the air conditioner change, run according to the changed running parameters for a set time before entering the condensation condition detection step.

[0165] The running parameters of the air conditioner include air speed adjustment, air deflector position adjustment, user set temperature adjustment, and environmental temperature change.

[0166] Due to the change of the operating parameters of the air conditioner, the temperature and / or humidity around the electric heating device changes after the air conditioner operates according to the changed operating parameters. In order to avoid condensation, the temperature around the electric heating device is determined again after the condensation condition detection step, and it is determined whether the electric heating device rotates according to the temperature around the electric heating device. In some embodiments, the electric heating device can be rotated by a set angle based on the current angle of the electric heating device, and in other embodiments, the electric heating device can also be restored to the initial angle, and then the temperature around the electric heating device is determined again after the condensation condition detection step, and it is determined whether the electric heating device rotates according to the temperature around the electric heating device.

[0167] As shown in Figure 7 Based on Embodiment Three, the control method of the air conditioner of the present embodiment is as follows:

[0168] S1, the air conditioner operates in refrigeration or dehumidification.

[0169] S2, the humidity sensor detects the humidity S, the detection module drives the temperature sensor to rotate around the electric heating device, and at least two temperatures detected by the temperature sensor during rotation are obtained.

[0170] S3, the maximum temperature Tmax and the minimum temperature Tmin are determined according to the temperatures detected by the temperature sensor, and the dew point temperature K is determined according to the maximum temperature Tmax and the humidity S.

[0171] S4, when the dew point temperature K is higher than the minimum temperature Tmin, step S5 is entered, otherwise, step S6 is entered.

[0172] S5, the electric heating device is driven to rotate by a set angle and maintained at the angle for a set time, and step S2 is entered.

[0173] S6, the electric heating device is stationary, and the air conditioner continues to operate according to the set state.

[0174] In step S6, when the angle of the electric heating device is explained, the temperature field around the electric heating device is uniform, which will not cause condensation of the electric heating device. Therefore, the electric heating device is stationary, and the air conditioner continues to operate according to the set state.

[0175] In some embodiments, in order to avoid the change of the operating time of the air conditioner to the temperature field around the electric heating device, thereby changing the condensation state of the electric heating device, in step S6, the air conditioner continues to operate according to the set state for a period of time, and then the condensation condition detection step is entered again to make a condensation determination, or in step S6, the condensation condition detection step is entered at a fixed time to make a condensation determination.

[0176] S7, the running parameter of the air conditioner is changed, if yes, go to step S8, otherwise, go to step S6.

[0177] S8, run according to the changed running parameter for a set time, go to step S2.

[0178] In some embodiments, in step S8, in the first cycle of the condensation condition detection step, in step S5, the electric heating driving device drives the electric heating device to rotate a set angle, which can continue to rotate a set angle from the current angle, or drive the electric heating device to return to the initial angle, and the subsequent cycle starts from the initial angle.

[0179] The embodiment adds an electric heating device driving device to the electric heating device, so that the electric heating device can adjust the angle according to the system setting during the actual operation of the air conditioner. The temperature sensor and the humidity sensor arranged around the electric heating device are used to monitor whether the temperature field around the electric heating device is uniform. When the temperature field reaches the set deviation range, the electric heating device is fixed at the angle. When the temperature field exceeds the set deviation range, the electric heating device is rotated until the position of the electric heating device makes the temperature field around it uniform. The embodiment can adjust the angle of the electric heating device according to the running state of the air conditioner, so as to make the temperature field around the electric heating device uniform, and avoid the condensation water produced by the alternating mixing of cold and hot air around the electric heating device and the dripping. When the temperature field around the electric heating device is uniform and the air conditioner continues to run according to the set state, it is further judged whether the running parameter of the air conditioner is changed. When the running parameter is changed, the air conditioner reenters the temperature field uniformity judgment. If it is not uniform, the angle of the electric heating device is adjusted to ensure that the electric heating device is always in a uniform temperature field.

Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments. However, any simple modification, equivalent change and modification of the above embodiments without departing from the technical solution of the present application, and according to the technical essence of the present application, still belong to the protection scope of the present application.
