For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

Based on the problem pointed out by the background art that the existing air conditioners with dust removal and purification modules are prone to condensation, the present invention provides a control method for the air conditioner, which aims to avoid condensation in the indoor unit when the temperature is too low Phenomenon, which will not produce water blowing phenomenon, nor will it pollute the indoor environment, nor will it cause safety accidents, and improve the user experience.

Specifically, the air conditioner of the present invention includes an indoor unit and a purification module. An air duct connecting the air inlet of the indoor unit and the air outlet of the indoor unit is formed in the indoor unit. The air conditioner further includes a drive for driving the movement of the purification module Mechanism, the driving mechanism can drive the purification module to move to the air inlet, and can also drive the purification module to move away from the air inlet, that is, under the drive of the driving mechanism, the air entering the air duct from the air inlet can all pass through the purification module, and It can pass through the purification module partly or not at all. Among them, the driving mechanism can be a linear motor, a rack and pinion driving mechanism, or a driving mechanism such as a hydraulic cylinder and a cylinder. Those skilled in the art can flexibly set the specific structure of the driving mechanism in practical applications, as long as the driving mechanism It only needs to be able to drive the purification module to move. In addition, in addition to the components of the air conditioner listed above, the air conditioner obviously also includes other components. These components are not related to the technical solution of the present invention, so they are not one by one here. List and repeat. It should be noted that the type of purification module can be flexibly selected, such as HEPA purification module and IFD purification module. In the present invention, the purification module is used as an example to illustrate the IFD purification module. The English full name of IFD is Intense Field Dielectric, which is Refers to a strong electric field using dielectric materials as carriers. The dielectric material forms a honeycomb hollow microchannel. The dielectric wraps the electrode sheet to form a strong electric field in the channel. It exerts a huge attraction on the charged particles moving in the air, and can absorb almost 100% of the air while generating only the minimum airflow resistance. Sports particles are particularly effective in removing particulate pollutants such as PM2.5. The IFD purification module can fully purify indoor air.

The following is a detailed description through two embodiments.

Example one

As shown in FIG. 1, the control method of the present invention includes: step S100, causing the air conditioner to perform a purification mode; step S102, acquiring the temperature of the air outlet of the indoor unit; and step S104, adjusting the position of the purification module according to the temperature of the air outlet of the indoor unit . That is, the position of the purification module is directly adjusted by detecting the temperature of the air outlet of the indoor unit, where the temperature of the air outlet can be detected by installing a temperature sensor at the air outlet of the indoor unit. In the present invention, when the air conditioner is performing the cooling condition, the IFD purification function is most likely to be condensed at this time. Therefore, if the IFD purification function is enabled when the air conditioner is in the cooling condition, then the temperature of the air outlet needs to be Judgment.

Preferably, the step of "adjusting the position of the purification module according to the temperature of the air outlet of the indoor unit" specifically includes: if the temperature of the air outlet of the indoor unit is less than or equal to the first preset temperature, moving the purification module away from the air inlet of the indoor unit (See FIG. 3, step S106 and step S108, Y represents the judgment result is yes, N represents the judgment result is no). In other words, when the temperature of the air outlet is low, the purification module is not suitable at the air inlet, that is, the IFD purification function should be temporarily stopped to ensure that the air flow at the air inlet will not be reduced due to the location of the purification module , That is, the temperature at the air inlet of the air conditioner will not be too low, and condensation will occur. Among them, those skilled in the art can flexibly set the first preset temperature in practical applications. For example, the first preset temperature can be set to 5 degrees Celsius, that is, when the temperature of the air outlet does not reach 5 degrees Celsius, the IFD The purification module moves away from the air inlet. Of course, the first preset temperature of 5 degrees Celsius is only exemplary, and can also be set to other temperatures. This adjustment and change of the first preset temperature does not constitute any limit to the present invention .

Preferably, the step of “adjusting the position of the purification module according to the temperature of the air outlet of the indoor unit” further includes: if the temperature of the air outlet of the indoor unit is greater than or equal to the second preset temperature, moving the purification module to the air inlet of the indoor unit (See FIG. 3, step S106, step S110, and step S112), where the second preset temperature is greater than the first preset temperature. That is to say, when the temperature of the air outlet is relatively high, there is no risk of condensation or the risk of condensation is very low, that is, the normal air purification function can be performed. At this time, the IFD purification module is moved to the air inlet. Among them, those skilled in the art can flexibly set the second preset temperature in practical applications. For example, the second preset temperature can be set to 8 degrees Celsius, that is, when the temperature of the air outlet reaches 8 degrees Celsius, the IFD can be purified The module moves to the air inlet. Of course, the second preset temperature of 8 degrees Celsius is only exemplary, and can also be set to other temperatures. This adjustment and change of the second preset temperature does not constitute any limit to the present invention .

It should be noted that when the temperature of the air outlet is between the first preset temperature and the second preset temperature (excluding the first preset temperature and the second preset temperature), the IFD purification module can be kept at the current position , That is, the position of the IFD module is not adjusted (see FIG. 3, step S106, step S110, and step S114).

Example 2

As shown in FIG. 2, the control method of the present invention includes: step S200, causing the air conditioner to perform a purification mode; step S202, acquiring the temperature of the air outlet of the indoor unit and the current position of the purification module; step S204, according to the temperature of the air outlet of the indoor unit And the current position of the purification module, selectively adjust the position of the purification module. Different from the first embodiment, this embodiment detects the current position of the purification module based on the temperature of the tuyere, and then determines whether the position of the purification module needs to be adjusted according to the current position of the purification module. Among them, the position detection of the purification module can be realized by a position sensor. In addition, as in the first embodiment, when the air conditioner is performing the cooling mode, turning on the IFD purification function at this time has the most risk of condensation. Therefore, when the air conditioner is in the cooling mode, if the IFD purification function is turned on, it is necessary to perform The judgment of the temperature of the air outlet and the current position of the purification module.

Preferably, the step of “selectively adjust the position of the purification module according to the temperature of the air outlet of the indoor unit and the current position of the purification module” specifically includes: if the temperature of the air outlet of the indoor unit is less than or equal to the first preset temperature and the purification module At the air inlet of the indoor unit, move the purification module away from the air inlet of the indoor unit (see FIG. 4, step S206, step S208, and step S210). In other words, when the temperature of the air outlet is low, the purification module is not suitable at the air inlet, that is, the IFD purification function should be temporarily stopped to ensure that the air flow at the air inlet will not be reduced due to the location of the purification module , That is, the temperature at the air inlet of the air conditioner will not be too low, and condensation will occur. Among them, those skilled in the art can flexibly set the first preset temperature in practical applications. For example, the first preset temperature can be set to 5 degrees Celsius, that is, when the temperature of the air outlet does not reach 5 degrees Celsius, the IFD The purification module moves away from the air inlet. Of course, the first preset temperature of 5 degrees Celsius is only exemplary, and can also be set to other temperatures. This adjustment and change of the first preset temperature does not constitute any limit to the present invention .

Preferably, the step of “selectively adjust the position of the purification module according to the temperature of the air outlet of the indoor unit and the current position of the purification module” further includes: if the temperature of the air outlet of the indoor unit is less than or equal to the first preset temperature and the purification module If it is not at the air inlet of the indoor unit, the position of the purification module is not adjusted or the purification module continues to move away from the air inlet of the indoor unit (see FIG. 4, step S206, step S208, and step S212). In other words, when the temperature of the air outlet is low, the purification module is not suitable at the air inlet, that is, the IFD purification function should be temporarily stopped to ensure that the air flow at the air inlet will not be reduced due to the location of the purification module , That is, the temperature at the air inlet of the air conditioner will not be too low, and condensation will occur. Therefore, if a part of the IFD purification module is still at the air inlet at this time, you need to continue to move the IFD purification module away from the air inlet. If the IFD purification module is no longer at the air inlet at this time, there is no need to adjust the position of the IFD purification module. .

Preferably, the step of "selectively adjusting the position of the purification module according to the temperature of the air outlet of the indoor unit and the current position of the purification module" further includes: if the temperature of the air outlet of the indoor unit is greater than or equal to the second preset temperature and the purification module If it is not at the air inlet of the indoor unit, the purification module is moved to the air inlet of the indoor unit (see FIG. 4, step S214, step S216, and step S218), where the second preset temperature is greater than the first preset temperature. That is to say, when the temperature of the air outlet is relatively high, there is no risk of condensation or the risk of condensation is very low, that is, the normal air purification function can be performed. At this time, the IFD purification module is moved to the air inlet. Among them, those skilled in the art can flexibly set the second preset temperature in practical applications. For example, the second preset temperature can be set to 8 degrees Celsius, that is, when the temperature of the air outlet reaches 8 degrees Celsius, the IFD can be purified The module moves to the air inlet. Of course, the second preset temperature of 8 degrees Celsius is only exemplary, and can also be set to other temperatures. This adjustment and change of the second preset temperature does not constitute any limit to the present invention .

Preferably, the step of "selectively adjusting the position of the purification module according to the temperature of the air outlet of the indoor unit and the current position of the purification module" further includes: if the temperature of the air outlet of the indoor unit is greater than or equal to the second preset temperature and the purification module At the air inlet of the indoor unit, the position of the purification module is not adjusted (see FIG. 4, step S214, step S216, and step S220). That is to say, when the temperature of the air outlet is relatively high, there is no risk of condensation or the risk of condensation is very low, that is, the normal air purification function can be performed. At this time, the IFD purification module is moved to the air inlet. If the IFD purification module is all at the air inlet at this time, there is no need to adjust the position of the IFD purification module.
