Background
In recent years, the problem that air outlet has peculiar smell in the process of refrigerating in the use process of the air conditioner is continuously generated, and after-sales complaints are caused. Analyzing the reason: the hydrophilic aluminum foil of the heat exchanger is formed by adhering a layer of organic paint on the surface of a base material aluminum product. The hydrophilic aluminum foil used in the air conditioner generally has the characteristics of high corrosion resistance, high hydrophilicity and the like. The coating coated on the outer part of the hydrophilic aluminum foil substrate is divided into an anti-corrosion coating layer and a hydrophilic coating layer.

Acrylic monomers are substances with relatively high odor, and under the condition of unreasonable production process setting, small molecular volatile matters and coating decomposition products are generated, and the substances have certain odor, and if the substances remain or adsorb on the surface of the aluminum foil, special odor is generated. After the low-temperature refrigeration operation, a large amount of condensed water can be enriched on the surface of the hydrophilic aluminum foil of the exchanger, and the water vapor brings peculiar smell into the air in the volatilization process.

In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "contacting," and "communicating" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
The peculiar smell of the air conditioner is that the filter screen does not completely filter the inlet air foreign matters, and a part of the foreign matters are attached to the surface of the evaporator, so that a temperature bed for bacteria breeding is formed in a wet environment, the bacteria breeding is promoted, and the mildew smell is generated. In addition, in the production process of the air conditioner, certain acid odor can be generated due to volatile matters generated by the hydrophilic coating chemical agent. In order to solve the problem of air-out peculiar smell during air conditioner refrigeration, the embodiment provides a control method of an air conditioner, wherein the air conditioner comprises a cleaning mode, the air conditioner automatically enters the cleaning mode after being refrigerated and started, and the air-out peculiar smell can be effectively removed by operating the cleaning mode.
As shown in the control flow chart of fig. 1, when the air conditioner operates in the cleaning mode, steps S1 to S3 are included, wherein:
s1, judging whether an air conditioner meets the set condition of first refrigeration starting;
s2, when the air conditioner meets the set condition of first refrigeration starting, acquiring indoor environment temperature; judging whether the indoor environment temperature is higher than the set temperature; if the indoor environment temperature is higher than the set temperature, controlling the air conditioner to operate according to a first operation strategy; if the indoor environment temperature is less than or equal to the set temperature, controlling the air conditioner to operate according to a second operation strategy; when the air conditioner does not meet the set condition of first refrigeration starting, controlling the air conditioner to operate according to a third operation strategy;
and S3, when the set condition for ending the cleaning mode is reached, controlling the air conditioner to exit the cleaning mode and operating the normal refrigeration mode. In some embodiments, when the running time of the cleaning mode reaches the set running time, the setting condition for ending the cleaning mode is judged to be reached, the air conditioner is controlled to exit the cleaning mode, and the normal refrigeration mode is operated.
In this embodiment, considering that bacteria growing in the indoor unit are different between the case of long-term non-cooling operation and the case of frequent cooling operation of the air conditioner, for example, in summer, the air conditioner frequently performs cooling operation, and the cleaning mode is also frequently started to remove the air outlet odor. If the air conditioner does not perform refrigeration operation for a long time, for example, the air conditioner performs refrigeration only in summer and does not perform refrigeration in spring, autumn and winter, the air conditioner does not perform refrigeration operation for a long time and does not clean the indoor unit, so that bacteria bred in the indoor unit are more, and the air outlet peculiar smell is serious. Therefore, different operation strategies are determined by judging whether the air conditioner operates for the first time, so that cleaning control is performed for different situations. In addition, under the condition of first refrigeration operation when the air conditioner is operated, the indoor environment temperature condition is also judged, and when the indoor environment is larger than the set temperature, the indoor environment is hot, and refrigeration is urgently needed. When the indoor environment temperature is lower than the set temperature, the indoor temperature is not too high, and the refrigerating requirement is not very strong, so that different operation strategies are determined according to the indoor environment temperature, and cleaning control is performed according to the urgent degree of the refrigerating requirement of a user.
By adopting the control method of the embodiment, the specific treatment and optimization are realized by distinguishing the first refrigeration operation from the non-first refrigeration operation and respective different logic control, and the indoor environment temperature is separately regulated, so that the cooling capacity requirement of a user is met as much as possible.
Further optionally, step S1 includes S11 to S13, wherein:
s11, acquiring the refrigerating start-up time of the time and calling the last refrigerating start-up time of the air conditioner;
s12, calculating a time interval ta between the current refrigeration starting and the last refrigeration starting, and comparing the time interval ta with a first set duration;
s13, the time interval ta satisfies the following conditions: ta is more than or equal to a first set time length, and judging that the startup meets the set condition of the first refrigeration startup; when the time interval ta satisfies: and ta is less than the first set duration, and judging that the current startup does not meet the set condition of the first refrigeration startup.
In this embodiment, the main board of the air conditioner includes a memory chip, and the memory chip stores the time of each refrigeration start-up operation. When the air conditioner is started in a refrigerating mode, the interval time ta between the current starting and the last refrigerating operation is detected, the heating mode is not detected, and if ta is more than or equal to a first set duration, for example, ta is more than 168h (one week or one month), the air conditioner is considered to be in the first refrigerating operation. The user can set the first setting time according to the self requirement, or the first setting time length is a fixed value and is stored in the control program and can not be changed.
Further alternatively, as shown in the control flowchart of fig. 2, when the air conditioner operates in the first operation policy, the control method of the first operation policy includes the steps of: a1 to A3, wherein:
a1, controlling the air conditioner to refrigerate, and operating the compressor at the highest operating frequency until the inner pipe temperature reaches within a first temperature range;
in the present embodiment, if the indoor environment temperature T Inner part Setting upConstant temperature T 0 Indicating that the user needs to perform the cooling in the first operation strategy. The compressor is then controlled to operate at a maximum frequency such that the internal tube temperature T1 is within a first temperature range, in one embodiment, 5 ℃ C. To T1 ℃ to 10 ℃. According to the common temperature range of refrigeration, the dew point temperature is basically above 12 ℃ when the indoor unit is started, the purpose of controlling the temperature of the indoor heat exchanger tube in the temperature range is to enable water in indoor air to be instantaneously condensed, but not be condensed and solidified to be called frost, so that the water is not easy to drain off in a few hours, and condensed water can be mutually contained with mould on the heat exchanger or adsorb paint volatile matters on the hydrophilic fins, and the condensed water is drained along with a water channel.
A2, after the compressor is started for a first set time, judging the size of a wind gear set by a user;
a3, when the wind level set by the user is smaller than or equal to the lowest wind level, controlling the inner fan to continuously run at the lowest wind level, controlling the air deflector to be opened at the minimum opening angle while the fan is started, and controlling the air deflector to be opened to the set opening angle after the air deflector is opened for a second set time; when the set wind level is greater than the lowest wind level, the wind level of the inner fan is controlled to run from low to high in sequence until the set wind level of the inner fan is reached, the air deflector is controlled to be opened at the minimum opening angle when the fan is started, and the air deflector is controlled to be opened to the set opening angle after the air deflector is opened for a third set time.
In this embodiment, in order to avoid dust, bacteria or paint volatile matter to directly blow into indoor environment after the air conditioner is started, and be favorable to the inner pipe temperature to reach target temperature rapidly, therefore the inner fan does not rotate after the compressor starts, and the inner fan is gradually started after the compressor starts for a first set time, so that preliminary deodorization is obtained, certain refrigerating capacity is ensured, and the requirement of a user is met. Meanwhile, after the compressor is started, the air deflector is kept closed, and after the internal fan is started, the air deflector and the internal fan are controlled in a program linkage manner, so that the air deflector is started at a minimum angle, and incomplete removal of peculiar smell in the early stage of starting is effectively prevented; meanwhile, when the fan is started at the minimum angle, the air outlet direction faces the roof, as shown in fig. 3, the position shown by the grid fixing 1 is the minimum opening angle of the air deflector, the air outlet direction is the direction shown by an arrow, the air outlet faces the roof at the moment, the air quantity is small, the customer perception is not strong if the peculiar smell exists, the foreign matters in the air conditioner are basically removed after a certain time, and the air deflector is controlled to be opened to the user set angle at the moment.
Meanwhile, the embodiment also defines that when the wind gear set by the user is smaller than or equal to the lowest wind gear of the inner fan, the inner fan is controlled to always operate at the lowest wind gear, and at the moment, the air guide plate is controlled to be opened to a set opening angle after the air guide plate is opened for a second set time; when the user sets that the wind gear is larger than the lowest wind gear, controlling the wind gear of the inner fan to sequentially run from low to high, and when the wind deflector is opened for a third set time, controlling the wind deflector to be opened to a set opening angle; the second setting time is preferably longer than or equal to the third setting time, because the foreign matter removal time in the air conditioner is longer when the air conditioner is always operated at the lowest wind level, if the user can feel the foreign smell when the foreign smell is not removed yet, the user can not feel the foreign smell when the air deflector is opened to the maximum opening angle, so that the air deflector needs to be limited to be opened to the second preset time at the minimum angle, and then the air deflector is opened to the user setting angle, at this time, the foreign smell is basically removed, and the user can not feel the foreign smell. When the wind gear of the inner fan is set to be larger, the peculiar smell can be removed rapidly in the process of upshifting from low to high, so that the peculiar smell is removed basically when the air deflector is opened to the user set angle after the air deflector is opened for a third set time at the minimum angle, and the user cannot feel the peculiar smell.
Preferably, in the process of controlling the wind gear of the inner fan to run sequentially from low to high, the inner fan is controlled to run in an upshift mode after each running wind gear keeps a fourth set time before the wind gear set by a user is reached, so that the inner fan is ensured to run stably.
In a specific embodiment, when the compressor is in high-frequency operation during the refrigeration start-up, the indoor fan is started to operate the lowest wind level after being started for 2 minutes, each wind level is allowed to be set to be higher than the wind level after being operated for 5 minutes, and if the user is the set lowest wind level, the air guide plate angle can be adjusted according to the user after being operated for at least 5 minutes. The air deflector is kept closed when the fan is started, the air deflector is stopped for 2min, the air deflector is allowed to be started to rotate after the fan is started, and the air deflector is stopped for at least 3min at a minimum angle.
Further alternatively, as shown in the control flowchart of fig. 2, when the air conditioner operates in the second operation strategy, the control method of the second operation strategy includes the steps of: b1 to B3, wherein:
b1, controlling an air conditioner to heat, and controlling a compressor to run at the highest frequency until the temperature of an inner pipe reaches a second temperature range; the first temperature range is less than the second temperature range;
b2, controlling the inner fan and the wind shield not to be started;
and B3, after the fifth set time, controlling the air conditioner to operate according to the first operation strategy.
In this embodiment, when the compressor is in the highest-frequency heating operation and the indoor fan is not in operation, the fan and the air deflector are not in operation, the inner tube temperature is within the second temperature range, and optionally, the inner tube temperature is within the second temperature range of T Inner pipe T2 ℃ and in a specific embodiment, T2 is less than or equal to 50 ℃ and less than or equal to 54 ℃, and most of bacteria and germs can be killed by the inner tube at the high temperature. The fan and the air deflector do not act, so that the temperature of the inner pipe can be rapidly increased, and the target value can be rapidly reached. According to the embodiment, the temperature of the copper pipe and the temperature of the fins are increased by heating, and then condensed water is easier to generate and the deodorizing effect is better when the second operation strategy refrigeration operation is executed.
Further alternatively, as shown in the control flowchart of fig. 2, when the air conditioner operates in the third operation policy, the control method of the third operation policy includes the steps of: c1 to C3, wherein:
c1, controlling the air conditioner to refrigerate, and operating the compressor at the highest operating frequency until the inner pipe temperature reaches a third temperature range;
c2, judging the size of a wind gear set by a user after the compressor is started for a fifth set time; the fifth set time is less than the first set time;
when the wind level is set to be less than or equal to the lowest wind level by a user, controlling the inner fan to continuously run at the lowest wind level, controlling the air deflector to be opened at the minimum opening angle while the fan is started, and controlling the air deflector to be opened to the set opening angle after the air deflector is opened for a sixth set time; the sixth set time is less than the second set time; when the wind level set by the user is greater than the lowest wind level, controlling the wind level of the inner fan to run sequentially from low to high until the wind level set by the user is reached, controlling the air deflector to be opened at the minimum opening angle while the fan is started, and controlling the air deflector to be opened to the set opening angle after the seventh set time is reached; the seventh set time is less than the third set time.
In this embodiment, when the air conditioner does not satisfy the condition of the first cooling operation, for example, ta is less than or equal to 168h (one week or one month), it is indicated that the air conditioner is frequently used, and at this time, the ambient temperature of the room is not determined, and the operation policy three is directly executed. The third operating strategy is the same as the first operating strategy in executing logic, but shortens the time of the relevant program, because the peculiar smell is removed frequently under the condition that the prototype is judged to be frequently used, and the peculiar smell can be removed quickly without the time of each execution, so that the refrigerating effect wanted by a user can be achieved as soon as possible.
Further optionally, during execution of the cleaning mode, the panel display of the air conditioner also displays execution codes of the cleaning mode; after the cleaning mode is ended, the execution code of the cleaning mode disappears.
In this embodiment, when the air conditioner executes the cleaning mode, the execution code of the cleaning mode is displayed on the panel display of the indoor unit, and it is indicated that the user is in the cleaning mode until the code disappears after the execution of the cleaning mode is completed. In some embodiments, the panel display displays uniform execution code, such as display code QJ, regardless of the operation policy the air conditioner performs; in other embodiments, the air conditioner displays different execution codes when executing different operation policies, such as display code Q1 when executing a first operation policy, display code Q2 when executing a first operation policy, and display code Q3 when executing a first operation policy.
Further alternatively, in the process of executing the cleaning mode, when a cleaning mode canceling instruction sent by a user is received, the air conditioner is controlled to cancel the cleaning mode, and the normal refrigeration mode is entered.
In this embodiment, since the air conditioner automatically enters the cleaning mode during the cooling operation, the cleaning mode code is displayed on the panel display, and the user can determine whether to operate the cleaning mode according to his own needs. If the user does not want to go through the cleaning mode process, the user can manually cancel, at the moment, the air conditioner does not execute the cleaning mode any more, the execution code on the panel display disappears, and the normal refrigeration mode is entered.
Further optionally, after receiving the shutdown command, controlling the compressor to shutdown; when the air deflector is a seamless air deflector, the air deflector is controlled to be closed to a minimum opening angle, the inner fan is controlled to continue to run for a set period of time with a minimum wind shield, and then the air deflector is controlled to be closed; when the air deflector is a seamless air deflector, the air deflector is controlled to be completely closed, and the internal fan is stopped after running for a set period of time with the minimum wind shield.
In this embodiment, no matter what operation strategy is, the air conditioner will have a process of blowing residual cold after stopping, so as to keep the interior of the air conditioner dry and avoid bacteria breeding. Therefore, after the air conditioner is shut down, the compressor is stopped, and the inner fan needs to be maintained for a certain time with the lowest wind level to blow out the residual cold in the system. Because the air guide plate is provided with the seamless air guide plate and the slotted air guide plate (or the microporous air guide plate), the operation state of the air guide plate is controlled according to the structure of the air guide plate after the air conditioner stops operating. When the air deflector is a slotted air deflector, the air deflector is controlled to be closed to the minimum stop, the internal fan is stopped after running for a set period of time with the minimum wind deflector, and then the air deflector is controlled to be closed. When the air deflector is a seamless air deflector, the air deflector is controlled to be completely closed, and the internal fan is stopped after running for a set period of time with the minimum wind shield.
In one embodiment, the air conditioner is shut down, and if the air deflector structure is fully closed, the seamless air deflector: the air deflector is firstly closed to the minimum stop grid, and the fan is stopped after running for 10 minutes with the minimum windshield, and then is completely closed. If the air deflector structure is not fully closed, a slotted air deflector (or a microporous air deflector): the air deflectors were all closed and the blower was shut down after 10 minutes running with a minimum damper.
