Referring to fig. 2, fig. 2 is a flowchart illustrating an anti-condensation method applied to the air conditioner 100 of fig. 1, and the method includes various steps described in detail below.
Step 201: the outdoor ambient humidity and the continuous operation time of the air conditioner cooling are determined.
Step 202: when the outdoor environment humidity is greater than or equal to the threshold, the indoor environment humidity is calculated according to the outdoor environment humidity and the continuous operation time.
Step 203: based on the indoor environment humidity, judging whether the condensation risk exists.
Step 204: based on the judgment result, the state of the air guide door of the air conditioner is controlled.
When the condensation risk exists, controlling a wind guide door of the air conditioner to be in a semi-closed state;
when the condensation risk does not exist, the air guide door of the air conditioner is controlled to be in a fully closed state, wherein the air guide door is provided with air dispersing holes for dispersing air flow, and the light wind effect is achieved.
The outdoor environment humidity is the humidity of the weather in the open air environment, and the continuous operation time of the air conditioner in the cooling state is determined.
Indoor environment humidity, in the unopened state of the air conditioner, the indoor environment humidity and the outdoor environment humidity are close.
The outdoor environment humidity and the threshold value are judged, and it should be noted that the threshold value may be set to 60%, 70%, 80%, etc., which is not particularly limited in the present invention.
When the air conditioner is refrigerating, the continuous operation time of the air conditioner is determined, and as the air conditioner is operated, the indoor environment humidity is lowered. The operation time of the air conditioner determines the variation of the indoor environment humidity, and thus, the indoor environment humidity is calculated based on the operation time of the air conditioner and the outdoor environment humidity.
According to the method and the device, the humidity sensor is not required to be installed in the room or the air conditioner, and the indoor environment humidity can be determined only by determining the continuous operation time of the air conditioner.
Based on the indoor environment humidity, judging whether the condensation risk exists. When the indoor environment humidity is too high, the risk of condensation exists, and when the indoor environment humidity is low, the risk of condensation does not exist.
Based on the indoor environment humidity, whether the condensation risk exists or not is judged, the indoor environment humidity can be compared with a preset humidity threshold, the preset humidity threshold is a critical value of the existence of the condensation risk and the absence of the condensation risk, a person skilled in the art can set the preset humidity threshold according to actual conditions, and the embodiment of the invention is not specific.
When there is condensation risk, the air guide door of the air conditioner is controlled to be in a semi-closed state, as shown in fig. 3, the air guide door is in a schematic view of the semi-closed state, and the reference numeral 1 is the air guide door, and in this state, the light wind effect is better, and condensation is not easy to generate. When there is no condensation risk, the air guide door of the air conditioner is controlled to be in a fully closed state, as shown in fig. 4, a schematic diagram of the air guide door in the fully closed state is shown, and reference numeral 1 is the air guide door, in this state, the light wind effect is optimal, and condensation is easy to generate when the air conditioner runs at a higher humidity.
And calculating the indoor environment humidity through the outdoor environment humidity and the continuous operation time of air conditioner refrigeration, judging whether the condensation risk exists or not based on the indoor environment humidity, and controlling the state of the air guide door based on a judging result. According to the scheme provided by the embodiment of the invention, indoor and outdoor environment humidity can be determined without additional installation of a humidity sensor, and when the condensation risk exists, the running frequency is not required to be reduced, and the occurrence of condensation is prevented by changing the state of the air guide door of the air conditioner, so that the refrigerating effect is not influenced, and the use experience of a user is improved.
In order to determine the outdoor environment humidity, in accordance with the above step 201, in another embodiment of the present application, as shown in fig. 5, there is provided an anti-condensation method, which specifically includes the following steps:
step 201-1: and determining the position information of the air conditioner in the state that the air conditioner is started.
Step 201-2: and determining weather information corresponding to the position information.
Step 201-3: and determining the environmental humidity information in the weather information as outdoor environmental humidity.
The air conditioner is networked without installing a humidity sensor, so that the position information of the air conditioner (Wi-Fi module) is acquired, and the position information can be accurate to the longitude and latitude of a cell; the server acquires local weather information according to the longitude and latitude information of the cell, and sends the outdoor weather information to an indoor unit main control unit of the air conditioner, so that environment humidity information in the weather information is determined and used as outdoor environment humidity.
According to the method and the device, the wifi module of the air conditioner is used for acquiring the position information of the air conditioner, determining weather information based on the position information, and finally determining the outdoor environment humidity based on the weather information. According to the scheme provided by the embodiment of the invention, the indoor environment humidity can be determined without additionally arranging a humidity sensor, so that the control cost of the air conditioner is reduced.
In another embodiment of the present application, as shown in fig. 6, an anti-condensation method is provided for the above step 202, which specifically includes the following steps:
step 202-1: the range to which the continuous run time belongs is determined.
Step 202-2: when the continuous operation time belongs to a first preset time range, a first correction value is determined.
Step 202-3: and calculating the difference between the outdoor environment humidity and the first correction value as the indoor environment humidity.
Step 202-4: and determining a second correction value when the continuous operation time belongs to a second preset time range.
Step 202-5: and calculating the difference between the outdoor environment humidity and the second correction value as the indoor environment humidity.
The first preset time range is smaller than the second preset time range, and the first correction value is smaller than the second correction value.
When the air conditioner is refrigerating, the continuous operation time of the air conditioner refrigerating is determined. After the air conditioner is started, the humidity of the room is reduced, and when the continuous operation time belongs to a first preset time range, the indoor environment humidity is calculated by determining a first correction value. For example: the first preset time range is [30min,60min ], and according to practical situations, under a scene with higher humidity, after the continuous running time of the air conditioner is in the first preset time range, the humidity can be reduced by at least 10%, namely, the first correction value is 10%, when the outdoor environment humidity is 70%, the difference between the outdoor environment humidity and the first correction value is calculated, namely, 70% -10% = 60%, and the current indoor environment humidity is 60%.
When the continuous operation time belongs to the second preset time range, the indoor environment humidity is calculated by determining a second correction value, for example: the second preset time range is [60min, n), n is a time value larger than 60min, and according to practical conditions, after running for 60min in a scene with higher humidity, the humidity of the room tends to be stable, and the humidity can be reduced by at least 15%, namely the second correction value is 15%. When the outdoor environment humidity is 70%, calculating the difference between the outdoor environment humidity and the second correction value, namely 70% -15% = 55%, and the current indoor environment humidity is 55%.
When the continuous operation time of refrigeration belongs to a third preset time range, the third preset time range can be (0, 30 min), the indoor environment humidity is reduced after the air conditioner needs to continuously operate for a period of time, and when the continuous operation time of the air conditioner for refrigeration is shorter, the indoor environment humidity cannot be changed, and then the outdoor environment humidity is close to the indoor environment humidity, so that the indoor environment humidity is higher, the condensation risk is easy to exist, and the direct control guide throttle is in a semi-closed state.
In another embodiment of the present application, as shown in fig. 7, an anti-condensation method is provided for the above step 203, which specifically includes the following steps:
step 203-1: and controlling the air guide door to be in a full closed state under the condition that the indoor environment humidity is smaller than the preset humidity and the difference value between the indoor environment temperature and the set environment temperature is not larger than 0.
And 203-2, controlling the air guide door to be in a semi-closed state under the condition that the indoor environment humidity is greater than the preset humidity and/or the difference value between the indoor environment temperature and the set environment temperature is greater than 0.
And when the indoor environment humidity is less than the preset humidity, judging that the condensation risk does not exist.
When the condensation risk does not exist, judging whether the refrigeration requirement of a user is met currently, and determining the indoor environment temperature and the set environment temperature, wherein the indoor environment temperature is the current indoor environment temperature, and the set environment temperature is the indoor environment temperature selected by the user in the air conditioner remote controller.
The preset humidity may be 70%, 65%, 60%, which is not particularly limited in the embodiment of the present invention.
And under the condition that the difference between the indoor environment temperature and the set environment temperature is not more than 0, indicating that the current environment temperature meets the refrigeration requirement of a user, and controlling the air guide door to be in a fully closed state.
When the indoor environment humidity is higher than the preset humidity, the risk of condensation exists, and in order to prevent the condensation, the air guide door is controlled to be in a semi-closed state.
When the indoor environment humidity is smaller than the preset humidity, the condensation risk is not shown, and the difference between the indoor environment temperature and the set environment temperature is larger than 0, the indoor environment temperature is not met with the refrigerating requirement of a user, and the air guide door is required to be controlled to be in a semi-closed state, so that the indoor temperature is reduced.
When the indoor environment humidity is greater than the preset humidity, and the difference between the indoor environment temperature and the set environment temperature is greater than 0, the air guide door is controlled to be in a semi-closed state so as to prevent the generation of condensation and the refrigeration requirement.
