Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioners, and particularly relates to a control method, device, air conditioner and storage medium for an air conditioner, and more particularly to a control method, device, air conditioner and storage medium for preventing odor blowing of an air conditioner. Background Art

[0002] In related solutions, most evaporators of air conditioners are aluminum foil fins + copper tubes and are coated, which can achieve long-term reliable operation; the coating is a water-based coating, and the water-based coating mainly uses organic coatings. During the baking process, long carbon chains will thermally crack and crosslink to form short carbon chain small molecules (such as methane, ethane, formic acid, acetic acid, methanol, ethanol, etc.), thereby generating odors. When the weight of the coating is relatively high, there are more cured polymers, and the number of short carbon chain small molecules generated will increase accordingly, resulting in the phenomenon that the heavier the coating weight, the greater the odor on the surface.

[0003] Therefore, when the air conditioner operates, the coating on the surface of the evaporator fins and copper tubes will volatilize to form an odor, which is blown into the room by the indoor fan blade, making the user feel the odor and affecting the user's comfort.

[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Considering that when an air conditioner operates, the coating on the surface of the evaporator fins and copper tubes will volatilize to form an odor, which is blown into the room by the indoor fan blades, making users feel the odor and affecting the comfort of users. At the same time, it is also one of the main reasons for after - sales complaints. Therefore, the solution of the present invention proposes a control method for an air conditioner, specifically a control method for preventing odor - emitting blowing of an air conditioner, so that by using this control method, it can be achieved that the condensed water formed by the evaporator covers the surface coating of the copper tubes and fins, and the formed water film can prevent the odor from volatilizing into the air, and at the same time, the refrigeration effect of the air conditioner can be ensured.

[0031] According to an embodiment of the present invention, there is provided a control method for an air conditioner, as Figure 1 shown in the schematic flow chart of an embodiment of the method of the present invention. The air conditioner has an indoor heat exchanger, the indoor heat exchanger has fins and copper tubes, and a water - based coating is coated on both the fins and copper tubes of the indoor heat exchanger. The control method of the air conditioner includes: step S110 to step S140.

[0032] At step S110, during the operation of the air conditioner after it is turned on, obtain the indoor environmental temperature of the air conditioner, obtain the target temperature of the air conditioner, and obtain the operating frequency of the compressor in the air conditioner.

[0033] At step S120, determine whether the indoor environmental temperature of the air conditioner reaches the target temperature of the air conditioner.

[0034] At step S130, if it is determined that the indoor environmental temperature of the air conditioner does not reach the target temperature of the air conditioner, then control the air conditioner to continue running.

[0035] At step S140, if it is determined that the indoor environmental temperature of the air conditioner has reached the target temperature of the air conditioner, then adjust the air volume gear of the indoor fan of the air conditioner according to the operating frequency of the compressor, or adjust the air volume gear of the indoor fan of the air conditioner and adjust the target temperature of the air conditioner, so as to form condensed water on the surface of the indoor heat exchanger, and then make the condensed water form a water film on the water-based coating on the fins and copper tubes of the indoor heat exchanger, so as to prevent the peculiar smell generated by the water-based coating from volatilizing into the indoor space of the room where the air conditioner is located.

[0036] A control method for preventing peculiar smell from blowing out of an air conditioner proposed by the solution of the present invention detects the room temperature and the operating state of the air conditioner, and modifies the air volume gear of the indoor unit of the air conditioner, the set temperature, the position of the air deflector, etc. according to the set conditions, so that during the operation of the air conditioner, it can be realized to use a water seal to solve the peculiar smell volatilization of the copper tube fin coating, etc., and at the same time ensure the refrigeration effect of the air conditioner. Among them, the operating state of the air conditioner refers to the operating mode of the air conditioner, such as the refrigeration operation, heating operation, air supply mode, dehumidification operation and other operating states of the air conditioner. The purpose of detecting the operating state of the air conditioner is to judge whether the anti-peculiar smell program needs to be executed according to the operating state of the air conditioner. Among them, in the air supply mode and the heating mode, the anti-peculiar smell operation is not executed, and in the dehumidification mode, the anti-peculiar smell operation is not executed either. In this way, by using this control method, it can be realized that the condensed water formed by the evaporator covers the surface coating of the copper tube and fins, and the formed water film can prevent the peculiar smell from volatilizing into the air, and at the same time can ensure the refrigeration effect of the air conditioner.

[0037] In some embodiments, for the specific process of adjusting the air volume gear of the indoor fan of the air conditioner according to the operating frequency of the compressor in step S140, or adjusting the air volume gear of the indoor fan of the air conditioner and adjusting the target temperature of the air conditioner, refer to the following exemplary description.

[0038] The following combines Figure 2Schematic diagram of an embodiment of the method of the present invention for adjusting the air volume setting and / or target temperature of the indoor fan according to the operating frequency of the compressor, further illustrating the specific process of adjusting the air volume setting and / or target temperature of the indoor fan according to the operating frequency of the compressor in step S140, including: steps S210 to S230.

[0039] Step S210, determine whether the operating frequency of the compressor is equal to the lower limit of the set frequency range. Wherein, the lower limit of the set frequency range is the lower limit frequency as follows.

[0040] Step S220, if it is determined that the operating frequency of the compressor is equal to the lower limit of the set frequency range, then adjust the air volume setting of the indoor fan of the air conditioner to the set silent setting.

[0041] Step S230, if it is determined that the operating frequency of the compressor is not equal to the lower limit of the set frequency range, then adjust the air volume setting of the indoor fan of the air conditioner to the original air volume setting, and use the temperature obtained by subtracting the set temperature from the target temperature of the air conditioner as the new target temperature of the air conditioner to control the air conditioner to operate according to the new target temperature of the air conditioner. Wherein, the set temperature is -1°C as follows.

[0042] Specifically, in the solution of the present invention, the user turns on the air conditioner to operate for cooling according to personal habits. When the room temperature drops to T 设定温度 , the anti-odor logic control is entered. Most users like to use the super-strong setting during the day and set the target temperature to 24 - 26°C. At night, users mostly like to use the high air volume setting and set the target temperature to 25 - 26°C.

[0043] In the solution of the present invention, the processing logic before optimization is: after the room temperature reaches T 设定温度 , F 压缩机运行频率 will decrease until it runs at the lower limit frequency. After running continuously for a period of time, the compressor stops. After the compressor stops, the indoor fan air volume setting maintains the original set air volume setting. When it is detected that T 房间温度 rises to T 设定温度 - 0.5°C, the compressor restarts to operate for cooling.

[0044] Among them, for the period of time when the compressor runs at the lower limit frequency, for the daytime, especially at noon, due to the high outdoor environment temperature, in a small room, the air conditioner will stop after running for about 2 hours (when the room temperature is lower than the set temperature, it will reach the temperature point and stop). For the night time, due to the low outdoor environment temperature, generally after the air conditioner runs for about 1 hour, it will stop (when the room temperature is lower than the set temperature, it will reach the temperature point and stop).

[0045] Before optimization, during the process when the compressor operates at the lower limit frequency, this stage is mainly to maintain the room temperature. Generally, the air outlet temperature of the indoor unit is not very low, and the tube temperature of the evaporator in the indoor unit is also relatively high. In this case, no condensed water can be condensed on the evaporator of the indoor unit due to the high temperature, and the peculiar smell of the coating will be sent into the room by the air supply, making the user feel the peculiar smell.

[0046] In the solution of the present invention, the optimized processing logic, that is, the control method for preventing peculiar smell blowing of the air conditioner, includes:

[0047] Step 1: After the room temperature reaches the target temperature T 设定温度 detect the operating frequency F of the compressor in the air conditioner 压缩机运行频率 .

[0048] Step 2: Judge whether F 压缩机运行频率 is equal to the lower limit frequency: if so, execute Step 21, otherwise execute Step 22.

[0049] Step 21: When F 压缩机运行频率 is equal to the lower limit frequency, correct the air volume gear of the indoor unit to the silent gear.

[0050] Optionally, when F 压缩机运行频率 is equal to the lower limit frequency, correct the air volume gear of the indoor unit to the silent gear, or it can also be the ultra-silent gear or stop the indoor fan to better condense condensed water on the evaporator to form a water seal state.

[0051] Step 22: When F 压缩机运行频率 is not equal to the lower limit frequency, the indoor unit maintains the original set air volume gear to operate for cooling, and at the same time corrects the target temperature, that is, the new target temperature = target temperature T 设定温度 -1°C to keep the air conditioner running stably.

[0052] For example: The room temperature is 28°C. A user turns on the air conditioner and sets it to 24°C. The air conditioner starts to cool, and the room temperature begins to drop. During the process when the room temperature drops to 24°C, the operating frequency of the air conditioner will decrease as the room temperature drops until it reaches the lowest operating frequency of 10 Hz to maintain the room temperature of 24°C. In the solution of the present invention, by correcting the air volume gear of the indoor unit, etc., condensed water is precipitated on the copper tube and fin of the evaporator, and the fin is a hydrophilic fin. The condensed water covering the fin and copper tube can form a water film covering the surface, which can solve the problem that the peculiar smell of the coating on the copper tube and fin during the refrigeration operation of the air conditioner affects the comfort of the user.

[0053] Among them, the lower limit frequency refers to the lowest operating frequency during the operation of the air conditioner. Generally speaking, after the room temperature reaches the user-set temperature, the air conditioner will reduce its operating frequency until it reaches the lowest operating frequency (i.e., the lower limit frequency) to maintain the room temperature and achieve energy-saving effects at the same time. The lowest operating frequencies of different air conditioners vary. For example, the lower limit frequency of the compressor of some air conditioners is 1 Hz, and the lower limit frequency of the compressors of most air conditioners is 10 Hz.

[0054] In some embodiments, the control method of the air conditioner according to the solution of the present invention further includes the process of continuously controlling the indoor fan and the air deflector after the air conditioner stops when the indoor environmental temperature of the air conditioner reaches the set shutdown temperature point.

[0055] The following Figure 3 shows a schematic flowchart of an embodiment of continuously controlling the indoor fan and the air deflector after the air conditioner stops when the indoor environmental temperature of the air conditioner in the method of the present invention reaches the set shutdown temperature point, and further illustrates the specific process of continuously controlling the indoor fan and the air deflector after the air conditioner stops when the indoor environmental temperature of the air conditioner reaches the set shutdown temperature point, including: steps S310 to S330.

[0056] Step S310, determine whether the indoor environmental temperature of the air conditioner reaches the set shutdown temperature point.

[0057] Step S320, if it is determined that the indoor environmental temperature of the air conditioner does not reach the set shutdown temperature point, then control the air conditioner to continue running.

[0058] Step S330, if it is determined that the indoor environmental temperature of the air conditioner has reached the set shutdown temperature point, then control the compressor of the air conditioner to stop, adjust the wind speed of the indoor fan of the air conditioner to the set ultra-low-noise wind speed, and adjust the position of the air deflector of the air conditioner to the set horizontal position. Among them, the set ultra-low-noise wind speed is lower than the set low-noise wind speed.

[0059] Specifically, in the solution of the present invention, the optimized processing logic, that is, the control method for the air conditioner to prevent odor from blowing, further includes: Step 3. After the air conditioner stops operating due to the indoor environmental temperature reaching the set temperature, the indoor unit fan is corrected to operate in an ultra-silent mode, and at the same time, the position of the air deflector is corrected to the horizontal position. For example: when the room temperature is 27 °C and the user sets the room temperature to 24 °C, the air conditioner starts to operate. During the refrigeration operation of the air conditioner, the room temperature will decrease, and at the same time, the operating frequency of the air conditioner will also decrease; when the room temperature drops to 24 °C, the air conditioner will operate at the lower limit frequency; when the air conditioner continues to cool down, when the room temperature < (set temperature - 2 °C), the air conditioner will stop operating. In addition, during refrigeration, the position of the air deflector is in the downwind duct position, aiming to have the maximum air volume and the most suitable air supply distance, forming a certain angle with the horizontal plane where the ground is located; when the position of the air deflector is corrected to the horizontal position, the air deflector is adjusted from the downwind duct position to the horizontal position, forming a parallel angle with the horizontal plane where the ground is located. The solution of the present invention can reduce the phenomenon of the air conditioner stopping at the temperature point, achieve better refrigeration control, further ensure the refrigeration effect, solve the problem of odor volatilization while ensuring the refrigeration effect of the air conditioner, and reduce the number of times the air conditioner stops at the temperature point.

[0060] In some embodiments, the control method of the air conditioner according to the solution of the present invention further includes: the process of continuously controlling the indoor fan and the compressor after the indoor environmental temperature of the air conditioner reaches the set shutdown temperature point and stops.

[0061] The following combines Figure 4 The schematic flow chart of an embodiment of continuously controlling the indoor fan and the compressor after the indoor environmental temperature of the air conditioner reaches the set shutdown temperature point in the method of the present invention shown below further illustrates the specific process of continuously controlling the indoor fan and the compressor after the indoor environmental temperature of the air conditioner reaches the set shutdown temperature point, including: Step S410 to Step S430.

[0062] Step S410, after the indoor environmental temperature of the air conditioner has reached the set shutdown temperature point and the compressor of the air conditioner has been controlled to stop, obtain the pipe temperature of the indoor heat exchanger.

[0063] Step S420, determine the temperature difference between the indoor environmental temperature of the air conditioner and the pipe temperature of the indoor heat exchanger, and determine the time required for the temperature difference to change by a set value, which is recorded as the temperature change time of the air conditioner. Wherein, the temperature change time of the air conditioner is like the time T 房间环境温度 -T 内管温度 ) for the temperature difference (T 时间 ) to change by 1 °C.

[0064] Step S430, control the compressor of the air conditioner to restart, and adjust the operating frequency of the compressor and the air volume gear of the indoor fan of the air conditioner according to the temperature change time of the air conditioner.

[0065] Specifically, in the solution of the present invention, the optimized processing logic, that is, the control method for the air conditioner to prevent peculiar smell from blowing, further includes: Step 4. After the indoor environmental temperature of the air conditioner reaches the temperature point and shuts down, detect and record the temperature T of the evaporator pipe of the indoor unit 内管温度 , the indoor environmental temperature T 房间环境温度 , judge the time T 房间环境温度 for the temperature difference (T 内管温度 - T 时间 ) to change by 1 °C, and further control the operation process of the air conditioner according to T 时间 . In the solution of the present invention, after the air conditioner reaches the temperature point and shuts down, detect the temperature T 内管温度 of the evaporator pipe of the indoor unit and the indoor environmental temperature T 房间环境温度 , optimize the restart operation logic to further ensure the room comfort and improve the comfort experience of users.

[0066] In some embodiments, in step S430, according to the temperature change time of the air conditioner, adjust the operating frequency of the compressor and adjust the air volume gear of the indoor fan of the air conditioner, including any one of the following adjustment situations:

[0067] The first adjustment situation: If the temperature change time of the air conditioner is less than the first set time, adjust the operating frequency of the compressor to the set high-frequency frequency and adjust the air volume gear of the indoor fan to the set air volume gear. Among them, the first set time is such as time01.

[0068] The second adjustment situation: If the temperature change time of the air conditioner is greater than or equal to the first set time and less than the second set time, adjust the operating frequency of the compressor to the set medium-frequency frequency and adjust the air volume gear of the indoor fan to the set air volume gear. Among them, the second set time is such as time02.

[0069] The third adjustment situation: If the temperature change time of the air conditioner is greater than or equal to the second set time, adjust the operating frequency of the compressor to the set low-frequency frequency and adjust the air volume gear of the indoor fan to the set air volume gear.

[0070] Specifically, in the solution of the present invention, the optimized processing logic, that is, the control method for the air conditioner to prevent peculiar smell from blowing, further includes: In step 4, step 41. When T 时间 < time01 (such as 3 min), the compressor starts and operates at high frequency, and the indoor unit fan operates according to the set air volume gear. Among them, time01 can be selected as 3 min, considering that after the air conditioner reaches the temperature point and shuts down, it is necessary to shut down for 3 min before allowing restart.

[0071] Step 42. When time01 (such as 3 min) < T 时间<time02 (e.g., 10 min), the compressor starts and operates at medium frequency, and the indoor unit fan operates according to the set fan speed.

[0072] Step 43. When time02 (e.g., 10 min) < T 时间 , the compressor starts and operates at low frequency, and the indoor unit fan operates according to the set fan speed.

[0073] The optimized logic mainly acts in the stage when the air conditioner maintains the room temperature. By using the condensed water formed on the evaporator copper tube to form a water seal phenomenon on the coating, it avoids the coating from volatilizing peculiar smells. At the same time, it optimizes the stage of maintaining the room temperature to enable the air conditioner to output better refrigeration effect. After the air conditioner stops when reaching the temperature point, it further optimizes the restart logic to quickly maintain the room temperature near the set temperature. Among them, the coating is an organic coating, which has peculiar smells after being processed by the process and will volatilize into the air. And using the condensed water to form a water film on the copper tube coating can cover the volatilization of the peculiar smells.

[0074] Figure 6 It is a schematic structural diagram of the fins and copper tube of the evaporator. As Figure 6 shown, both the outside of the copper tube and the fins are coated with a water-based coating. The condensed water droplets generated on the water-based coating form a water film on the copper tube coating, which can cover the volatilization of the peculiar smells. After verification, the anti-peculiar smell effect is good, and the odor detection results are shown in the following table:

[0075]

[0076] Adopting the technical solution of this embodiment, during the operation of the air conditioner, the indoor environmental temperature and the target temperature of the air conditioner are obtained. After the indoor environmental temperature of the air conditioner reaches the target temperature, when the operating frequency of the compressor of the air conditioner reaches the set lower limit frequency, the fan speed of the indoor fan is adjusted to the silent gear. When the operating frequency of the compressor of the air conditioner does not reach the set lower limit frequency, the fan speed of the indoor fan is maintained at the original fan speed, and the target temperature of the air conditioner is adjusted downwards, so that condensed water is precipitated on the copper tube and fins of the indoor heat exchanger to form a water film. Thus, by covering the surface coating of the copper tube and fins with the condensed water formed by the indoor heat exchanger, the water film formed by the condensed water is used to prevent the coating peculiar smell from volatilizing into the indoor air, which is beneficial to improving the comfort of users.

[0077] According to an embodiment of the present invention, there is also provided a control device for an air conditioner corresponding to the control method of the air conditioner. Refer to Figure 5 the schematic structural diagram of an embodiment of the device of the present invention shown. The air conditioner has an indoor heat exchanger, and the indoor heat exchanger has fins and a copper tube. Both the fins and the copper tube of the indoor heat exchanger are coated with a water-based coating. The control device of the air conditioner includes: an acquisition unit 102 and a control unit 104.

[0078] Among them, the acquisition unit 102 is configured to acquire the indoor environmental temperature of the air conditioner, the target temperature of the air conditioner, and the operating frequency of the compressor in the air conditioner during the operation after the air conditioner is turned on. For the specific functions and processing of the acquisition unit 102, refer to step S110.

[0079] The control unit 104 is configured to determine whether the indoor environmental temperature of the air conditioner reaches the target temperature of the air conditioner. For the specific functions and processing of the control unit 104, refer to step S120.

[0080] The control unit 104 is further configured to control the air conditioner to continue operating if it is determined that the indoor environmental temperature of the air conditioner does not reach the target temperature of the air conditioner. For the specific functions and processing of the control unit 104, refer to step S130.

[0081] The control unit 104 is further configured to, if it is determined that the indoor environmental temperature of the air conditioner has reached the target temperature of the air conditioner, adjust the air volume gear of the indoor fan of the air conditioner according to the operating frequency of the compressor, or adjust the air volume gear of the indoor fan of the air conditioner and adjust the target temperature of the air conditioner, so as to form condensed water on the surface of the indoor heat exchanger, and then form a water film on the water-based coating on the fins and copper tubes of the indoor heat exchanger, so as to prevent the peculiar smell generated by the water-based coating from volatilizing into the indoor space of the room where the air conditioner is located. For the specific functions and processing of the control unit 104, refer to step S140.

[0082] A control device for preventing peculiar smell blowing of an air conditioner proposed by the solution of the present invention detects the room temperature and the operating state of the air conditioner, and corrects the air volume gear of the indoor unit of the air conditioner, the set temperature, the position of the air deflector, etc. according to the set conditions, so that the air conditioner can use a water seal to solve the peculiar smell volatilization of the copper tube fin coating, etc. during the operation process, and at the same time ensure the refrigeration effect of the air conditioner. In this way, by using this control device, it is possible to use the condensed water formed by the evaporator to cover the surface coating of the copper tube and fins, and the formed water film can prevent the peculiar smell from volatilizing into the air, and at the same time ensure the refrigeration effect of the air conditioner.

[0083] In some embodiments, the control unit 104 adjusts the air volume gear of the indoor fan of the air conditioner according to the operating frequency of the compressor, or adjusts the air volume gear of the indoor fan of the air conditioner and adjusts the target temperature of the air conditioner, including:

[0084] The control unit 104 is specifically further configured to determine whether the operating frequency of the compressor is equal to the lower limit of the set frequency range. Among them, the lower limit of the set frequency range is the lower limit frequency. For the specific functions and processing of the control unit 104, refer to step S210.

[0085] The control unit 104 is further specifically configured to adjust the air volume gear of the indoor fan of the air conditioner to a set silent gear if it is determined that the operating frequency of the compressor is equal to the lower limit of the set frequency range. For the specific functions and processes of this control unit 104, please also refer to step S220.

[0086] The control unit 104 is further specifically configured to adjust the air volume gear of the indoor fan of the air conditioner to the original set air volume gear if it is determined that the operating frequency of the compressor is not equal to the lower limit of the set frequency range, and use the temperature obtained by subtracting the set temperature from the target temperature of the air conditioner as the new target temperature of the air conditioner to control the air conditioner to operate according to the new target temperature of the air conditioner. Wherein, the set temperature is, for example, -1°C. For the specific functions and processes of this control unit 104, please also refer to step S230.

[0087] Specifically, in the solution of the present invention, the user turns on the air conditioner to operate for cooling according to personal habits. When the room temperature drops to T 设定温度 , the anti-odor logic control is entered. Most users like to use the super strong gear during the day and set the target temperature to 24-26°C. At night, most users like to use the high air volume gear and set the target temperature to 25-26°C.

[0088] In the solution of the present invention, the processing logic before optimization is: after the room temperature reaches T 设定温度 , F 压缩机运行频率 will decrease until it runs at the lower limit frequency and continues to run for a period of time before the compressor stops. After the compressor stops, the air volume gear of the indoor unit maintains the original set air volume gear and runs. When it is detected that T 房间温度 rises to T 设定温度 -0.5°C, the compressor restarts and runs for cooling.

[0089] Among them, for the period of time when the compressor runs at the lower limit frequency, for the time of day, around noon, because the outdoor environment is hot, in a small room, the air conditioner will stop running after about 2 hours of operation (when the room temperature is lower than the set temperature, it will reach the temperature point and stop). For the night time, the outdoor environment temperature is low, and generally after about 1 hour of operation of the air conditioner, it will stop running (when the room temperature is lower than the set temperature, it will reach the temperature point and stop).

[0090] Before optimization, during the process when the compressor runs at the lower limit frequency, this stage is mainly to maintain the room temperature. Generally, the air outlet temperature of the indoor unit is not very low, and the temperature of the inner pipe of the evaporator of the indoor unit is also relatively high. In this case, no condensed water can be condensed on the evaporator of the indoor unit due to the high temperature, and the odor of the coating will be sent into the room by the air supply, making the user feel the odor.

[0091] In the solution of the present invention, the optimized processing logic, that is, the control device for anti-odor blowing of the air conditioner, includes:

[0092] Step 1: After the room temperature reaches the target temperature T 设定温度 , detect the operating frequency F of the compressor in the air conditioner 压缩机运行频率 .

[0093] Step 2: Determine whether F 压缩机运行频率 is equal to the lower limit frequency: if so, execute Step 21; otherwise, execute Step 22.

[0094] Step 21: When F 压缩机运行频率 is equal to the lower limit frequency, correct the indoor fan speed to the silent gear.

[0095] Optionally, when F 压缩机运行频率 is equal to the lower limit frequency, correct the indoor fan speed to the silent gear, or it can also be the ultra-silent gear or stop the indoor fan to better condense dew on the evaporator to form a water seal state.

[0096] Step 22: When F 压缩机运行频率 is not equal to the lower limit frequency, the indoor unit maintains the original set fan speed to cool down, and at the same time corrects the target temperature, that is, the new target temperature = target temperature T 设定温度 - 1°C to keep the air conditioner running stably.

[0097] For example: The room temperature is 28°C. A user turns on the air conditioner and sets it to 24°C. The air conditioner starts to cool, and the room temperature begins to drop. During the process of the room temperature dropping to 24°C, the operating frequency of the air conditioner will decrease as the room temperature drops until it reaches the lowest operating frequency of 10 Hz to maintain the room temperature of 24°C. In the solution of the present invention, by correcting the indoor fan speed, etc., dew is condensed on the evaporator copper tube and fin, and the fin is a hydrophilic fin. The dew covers the fin and copper tube to form a water film covering the surface, which can solve the problem that the odor volatilization of the copper tube, fin coating, etc. affects the comfort of the user during the air conditioning cooling operation.

[0098] Among them, the lower limit frequency refers to the lowest operating frequency during the operation of the air conditioner. Generally speaking, after the room temperature reaches the user-set temperature, the air conditioner will reduce the operating frequency until it reaches the lowest operating frequency (i.e., the lower limit frequency) to maintain the room temperature and achieve the energy-saving effect at the same time. The lowest operating frequencies of different air conditioners are different. For example, the lower limit frequency of the compressor of some air conditioners is 1 Hz, and the lower limit frequency of the compressor of most air conditioners is 10 Hz.

[0099] In some embodiments, the control device of the air conditioner described in the solution of the present invention further includes: the process of continuing to control the indoor fan and the air deflector after the air conditioner stops when the indoor environmental temperature reaches the set shutdown temperature point, as follows:

[0100] The control unit 104 is further configured to determine whether the indoor environmental temperature of the air conditioner reaches a set shutdown temperature point. For the specific functions and processes of this control unit 104, refer to step S310.

[0101] The control unit 104 is further configured to, if it is determined that the indoor environmental temperature of the air conditioner does not reach the set shutdown temperature point, control the air conditioner to continue operating. For the specific functions and processes of this control unit 104, refer to step S320.

[0102] The control unit 104 is further configured to, if it is determined that the indoor environmental temperature of the air conditioner has reached the set shutdown temperature point, control the compressor of the air conditioner to shut down, adjust the air volume gear of the indoor fan of the air conditioner to a set ultra - quiet air volume gear, and adjust the position of the air deflector of the air conditioner to a set horizontal position. Among them, the set ultra - quiet air volume gear is less than the set quiet air volume gear. For the specific functions and processes of this control unit 104, refer to step S330.

[0103] Specifically, in the solution of the present invention, the optimized processing logic, that is, the control device for preventing odor blowing of the air conditioner, further includes: Step 3: After the air conditioner shuts down due to the condition that the indoor environmental temperature reaches the set temperature, the indoor unit fan is corrected to operate in an ultra - quiet mode, and at the same time, the position of the air deflector is corrected to the horizontal position. The solution of the present invention can reduce the phenomenon that the air conditioner shuts down when reaching the temperature point, has better refrigeration control, further ensures the refrigeration effect, solves the problem of odor volatilization while ensuring the refrigeration effect of the air conditioner, and reduces the number of times the air conditioner shuts down when reaching the temperature point.

[0104] In some embodiments, the control device of the air conditioner according to the solution of the present invention further includes the process of continuously controlling the indoor fan and the compressor after the air conditioner shuts down when the indoor environmental temperature of the air conditioner reaches the set shutdown temperature point, which is specifically as follows:

[0105] The acquisition unit 102 is further configured to, after the indoor environmental temperature of the air conditioner has reached the set shutdown temperature point and the compressor of the air conditioner has been controlled to shut down, acquire the pipe temperature of the indoor heat exchanger. For the specific functions and processes of this acquisition unit 102, refer to step S410.

[0106] The control unit 104 is further configured to determine the temperature difference between the indoor environmental temperature of the air conditioner and the pipe temperature of the indoor heat exchanger, and determine the time required for this temperature difference to change by a set value, which is recorded as the temperature change time of the air conditioner. Among them, the temperature change time of the air conditioner is like the time T 房间环境温度 -T 内管温度 ) for the temperature difference (T 时间 ) to change by 1°C. For the specific functions and processes of this control unit 104, refer to step S420.

[0107] The control unit 104 is further configured to control the compressor of the air conditioner to restart, adjust the operating frequency of the compressor according to the temperature change time of the air conditioner, and adjust the air volume level of the indoor fan of the air conditioner. For the specific functions and processes of this control unit 104, refer to step S430.

[0108] Specifically, in the solution of the present invention, the optimized processing logic, that is, the control device for preventing peculiar smell blowing of the air conditioner, further includes: Step 4. After the indoor environmental temperature of the air conditioner reaches the temperature point and shuts down, detect and record the tube temperature T of the evaporator of the indoor unit 内管温度 and the indoor environmental temperature T 房间环境温度 , judge the time T 房间环境温度 for the temperature difference (T 内管温度 -T 时间 ) to change by 1 °C, and further control the operation process of the air conditioner according to T 时间 . In the solution of the present invention, after the air conditioner reaches the temperature point and shuts down, detect the tube temperature T 内管温度 of the evaporator of the indoor unit and the indoor environmental temperature T 房间环境温度 , optimize the restart operation logic, further ensure the comfort of the room, and improve the comfort experience of users.

[0109] In some embodiments, the control unit 104 adjusts the operating frequency of the compressor and the air volume level of the indoor fan of the air conditioner according to the temperature change time of the air conditioner, including any of the following adjustment situations:

[0110] The first adjustment situation: The control unit 104 is specifically further configured to, if the temperature change time of the air conditioner is less than the first set time, adjust the operating frequency of the compressor to the set high-frequency frequency and adjust the air volume level of the indoor fan to the set air volume level. Among them, the first set time is such as time01.

[0111] The second adjustment situation: The control unit 104 is specifically further configured to, if the temperature change time of the air conditioner is greater than or equal to the first set time and less than the second set time, adjust the operating frequency of the compressor to the set medium-frequency frequency and adjust the air volume level of the indoor fan to the set air volume level. Among them, the second set time is such as time02.

[0112] The third adjustment situation: The control unit 104 is specifically further configured to, if the temperature change time of the air conditioner is greater than or equal to the second set time, adjust the operating frequency of the compressor to the set low-frequency frequency and adjust the air volume level of the indoor fan to the set air volume level.

[0113] Specifically, in the solution of the present invention, the optimized processing logic, that is, the control device for preventing peculiar smell blowing of the air conditioner, further includes: In step 4, step 41. When T 时间<time01 (such as 3 min), the compressor starts and operates at high frequency, and the indoor unit fan operates according to the set fan speed. Among them, time01 can be selected as 3 min, considering that after the air conditioner stops when reaching the temperature point, it needs to stop for 3 min before it is allowed to restart.

[0114] Step 42: When time01 (such as 3 min) < T 时间 < time02 (such as 10 min), the compressor starts and operates at medium frequency, and the indoor unit fan operates according to the set fan speed.

[0115] Step 43: When time02 (such as 10 min) < T 时间 , the compressor starts and operates at low frequency, and the indoor unit fan operates according to the set fan speed.

[0116] The optimized logic mainly acts on the stage when the air conditioner maintains the room temperature. By using the condensed water formed on the evaporator copper tube to form a water seal phenomenon on the coating, it can avoid the coating from volatilizing peculiar smells. At the same time, the stage of maintaining the room temperature is optimized to enable the air conditioner to output better refrigeration effect. After the air conditioner stops when reaching the temperature point, the restart logic is further optimized to quickly maintain the room temperature near the set temperature. Among them, the coating is an organic coating, which has peculiar smells after being processed by the process and will volatilize into the air. And by using the condensed water to form a water film on the copper tube coating, it can cover the volatilization of the peculiar smell.

[0117] Figure 6 It is a schematic structural diagram of the fins and copper tubes of the evaporator. As Figure 6 shown, both the copper tubes and the fins are coated with a water-based coating. The condensed water droplets generated on the water-based coating form a water film on the copper tube coating, which can cover the volatilization of the peculiar smell. After verification, the anti-peculiar smell effect is good. The odor detection results are shown in the following table:
