The embodiments described in the following examples do not represent all embodiments consistent with the present application. But merely as exemplifications of systems and methods consistent with certain aspects of the application, as recited in the claims.
A makeup refrigerator, also called a cosmetic refrigerator, is a special refrigerator for specially storing skin care products, makeup products and nutrients, and can provide an antibacterial closed environment for the cosmetics through constant temperature and humidity so as to ensure active ingredients and skin care effects of the cosmetics and prolong the service life. The cosmetic refrigerator is mainly used for storing skin care products and beauty products, and besides the storage requirement, more people also regard the cosmetic refrigerator as a color value representative for improving the home style grade. It should be noted that the refrigerator and the fan speed control method of the present application are not limited to the cosmetic refrigerator, and may also be applied to a common household refrigerator or a commercial refrigerator in a place of business.
As most users choose to place the cosmetic refrigerator in a bedroom dressing table, the noise reduction requirement of people on the cosmetic refrigerator is higher and higher.
In order to meet the noise reduction requirement of a user on a cosmetic refrigerator, some embodiments of the present application provide a method for controlling a rotational speed of a blower of a refrigerator, with reference to fig. 1, the method includes:
acquiring an initial temperature, a target set temperature and an ambient temperature in a refrigerator;
the in-box starting temperature of the refrigerator is the temperature in the refrigerator when the rotating speed of a fan of the refrigerator is controlled, the target set temperature is the target temperature which is set by a user or a manufacturer and is required to be reached in the beauty refrigerator, and the environment temperature is the temperature of the external environment where the beauty refrigerator is placed.
For example, when the rotational speed of the fan of the refrigerator is controlled, the internal temperature of the refrigerator is 18 ℃, that is, the initial temperature in the refrigerator is 18 ℃, the temperature to be reached by the refrigerator is 16 ℃, that is, the target set temperature is 16 ℃, and the external ambient temperature of the refrigerator is 22 ℃, that is, the ambient temperature is 22 ℃.
And generating a fan rotating speed regulating instruction according to the initial temperature in the box, the target set temperature and the environment temperature. The fan rotating speed adjusting instruction is used for controlling the fan to operate in one mode of a fixed low rotating speed mode, a target set rotating speed mode or a conventional rotating speed mode, wherein the fixed low rotating speed mode is the working state of the fan when the fan operates at a speed lower than the conventional rotating speed, the target set rotating speed mode is the working state of the fan when the fan operates at the target rotating speed corresponding to the target set temperature, the conventional rotating speed mode is the working state of the fan when the fan operates at the conventional rotating speed, and the conventional rotating speed is the rotating speed of the fan when the fan normally operates at the corresponding ambient temperature.
The fan speed in the fixed low speed mode, the target set speed mode or the normal speed mode of the fan is set by the manufacturer, for example, the fan speed in the normal speed mode may be set to 3000 rpm, the fan speed in the fixed low speed mode may be set to 1500 rpm, and the fan speed in the target set speed mode may be determined according to the required target temperature.
After the initial temperature, the target set temperature and the ambient temperature in the refrigerator are obtained, the fan rotating speed of the refrigerator can be properly adjusted according to the values of the temperatures, and the noise generated when the beauty refrigerator operates is reduced by reducing the fan rotating speed. For example, when the fan of the refrigerator is adjusted from the normal rotating speed mode to the fixed low rotating speed mode, the rotating speed of the fan of the refrigerator is greatly reduced, the noise generated by the fan is also obviously reduced, and the same is true when the fan of the refrigerator is adjusted from the target set rotating speed mode to the fixed low rotating speed mode.
Referring to fig. 2, a flow chart of a method for determining an operating time period of a refrigerator provided by the present application is shown, and in some embodiments, the method further includes:
determining the working time periods of the refrigerator, wherein the working time periods comprise daytime time periods and nighttime time periods;
the refrigerator is internally provided with a clock module, and when the working time period of the refrigerator is determined, the clock module firstly acquires the current time and then judges whether the refrigerator is in the daytime time period or the nighttime time period according to the current time.
For example, when the current time period is located at 07-00, the refrigerator is considered to be in the daytime time period, and when the current time period is located at 22-07 of the following day.
When the refrigerator is in a daytime time period, generating a first fan rotating speed adjusting instruction, wherein the first fan rotating speed adjusting instruction is used for controlling the fan to operate in a conventional rotating speed mode;
when the refrigerator is in the daytime, the user does not have a rest in the bedroom at the time, and the cosmetic refrigerator does not need to reduce noise, so that a first fan rotating speed adjusting instruction is generated, the fan of the cosmetic refrigerator runs in a conventional rotating speed mode, and the noise generated by the cosmetic refrigerator in the mode is the noise of the conventional cosmetic refrigerator.
And when the refrigerator is in a night time period, generating a second fan rotating speed adjusting instruction, wherein the second fan rotating speed adjusting instruction is used for controlling the fan to operate in a fixed low rotating speed mode.
When the refrigerator is in the night time period, the user in the bedroom is considered to have a rest at the moment, the noise of the beauty refrigerator needs to be reduced, and therefore a second fan rotating speed adjusting instruction is generated, the fan of the beauty refrigerator operates in a fixed low rotating speed mode, the rotating speed of the fan is very low in the mode, and the noise generated by the fan is also very small.
In some embodiments, the method further comprises:
calculating the difference value between the target set temperature of the refrigerator and the initial temperature in the refrigerator;
and when the difference value is larger than a first preset temperature difference threshold value, generating a third fan rotating speed adjusting instruction, wherein the third fan rotating speed adjusting instruction is used for controlling the fan to operate in a target set rotating speed mode.
When the difference is greater than the first preset temperature difference threshold, the difference between the internal temperature of the refrigerator and the expected temperature of the skin care product to be stored is considered to be large, and the internal temperature of the refrigerator at the moment may cause the skin care product stored in the refrigerator to deteriorate rapidly, so that the rotating speed of the fan needs to be adjusted to enable the fan to operate in a target set rotating speed mode, and the internal temperature of the refrigerator reaches the ideal temperature of the skin care product to be stored, which is required by a user, as soon as possible.
The first preset temperature difference threshold value is set to be 2, namely when the difference value between the target set temperature of the refrigerator and the initial temperature in the refrigerator is larger than 2, a third fan rotating speed adjusting instruction is generated to directly control the fan to operate in a target set rotating speed mode, noise of the beauty and make-up refrigerator is likely to be large, and in order to maintain the constant internal temperature, the shelf life of the skin care products stored in the beauty and make-up refrigerator can be prolonged.

in the heating mode of the refrigerator, cold air is blown out of the refrigerator body through the fan, hot air is blown into the refrigerator body, and the fan sucks air in the refrigerator to return air, so that air path circulation is formed, and the heating function in the refrigerator is realized.
Under the refrigeration mode of the refrigerator, hot air is blown out of the refrigerator body through the fan, and cold air is blown into the refrigerator body to form air path circulation, so that the refrigeration function inside the refrigerator is realized.
When the refrigerator is in a refrigeration mode, calculating a difference value between a target set temperature of the refrigerator and an initial temperature in the refrigerator, and when the difference value is smaller than a first preset temperature difference threshold value, generating a first fan rotating speed adjusting instruction so as to control the fan to operate in a conventional rotating speed mode;
when the refrigerator is in a refrigeration mode, if the difference value between the target set temperature of the refrigerator and the initial temperature in the refrigerator is less than 2, a first fan rotating speed adjusting instruction is generated to control the fan to operate in a conventional rotating speed mode, and the noise generated by the beauty refrigerator in the mode is the noise of the conventional beauty refrigerator.
Namely, when the refrigerator is in a refrigeration mode, if the difference value between the target set temperature of the refrigerator and the initial temperature in the refrigerator is less than 2, the rotating speed of the fan is controlled to be the conventional rotating speed, the noise is low, and if the difference value between the target set temperature of the refrigerator and the initial temperature in the refrigerator is more than 2, the rotating speed of the fan is controlled to be the target set rotating speed, the refrigeration is accelerated, and the purpose of prolonging the shelf life of skin care products of the cosmetic refrigerator is achieved.

Namely, when the refrigerator is in a heating mode, if the difference value between the target set temperature of the refrigerator and the initial temperature in the refrigerator is less than 4, the rotating speed of the fan is controlled to be the conventional rotating speed, the noise is low, and if the difference value between the target set temperature of the refrigerator and the initial temperature in the refrigerator is more than 4, the rotating speed of the fan is controlled to be the target set rotating speed, the heating is accelerated, and the purpose of prolonging the shelf life of skin care products of the beauty refrigerator is achieved.
Referring to fig. 3, which is a flowchart of a method for detecting an operating mode of a refrigerator provided by the present application, in some embodiments, the step of detecting the operating mode of the refrigerator includes:
comparing the initial temperature in the refrigerator with the ambient temperature;
when the difference value between the initial temperature in the refrigerator and the ambient temperature is greater than 0, comparing the initial temperature in the refrigerator with a target set temperature;
when the initial temperature in the refrigerator is lower than the target set temperature, the refrigerator is set to operate in a heating mode; and when the initial temperature in the refrigerator is higher than the target set temperature, the refrigerator is set to operate in a refrigeration mode.
When the temperature difference exists between the initial temperature in the refrigerator and the ambient temperature, the initial temperature in the refrigerator is compared with the target set temperature, and whether the working mode of the refrigerator is a refrigerating mode or a heating mode is determined according to the initial temperature in the refrigerator and the target set temperature.
