Drawings
The invention is further illustrated with reference to the following figures and examples:
FIG. 1 is a schematic diagram of an embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.
Referring to fig. 1, the present invention provides a refrigerator noise reduction method, wherein a control terminal 200 electrically connected to a refrigerator 100 is provided, and the refrigerator 100 is controlled by the control terminal 200 in a manner a, specifically, when the control terminal 200 detects that no person is in a set area or no person is in a set time limit, the control terminal 200 automatically switches the refrigerator 100 from a first state to a second state with higher operating noise than the first state for cooling.
When the mode A is adopted to control the refrigerator 100, the refrigerator 100 can be kept in the first state with low noise when people exist, and the refrigerator is switched to the second state to perform high-power refrigeration when no people exist. Wherein the first state may be either a standby state or a state of low power (i.e. lower operating power than the second state) operation.
When the refrigerator 100 is an in-vehicle refrigerator, in the mode a, the control terminal 200 is correspondingly configured as an automobile, and sends a first electric signal to the refrigerator 100 when the automobile detects that there is a person in the automobile, the refrigerator 100 enters a first state, and sends a second electric signal to the refrigerator 100 when the automobile detects that there is no person in the automobile, and the refrigerator 100 enters a second state.
Because the existing automobile basically has the function of judging whether the personnel exist in the automobile, when the automobile judges whether the personnel exist in the automobile, the system of the automobile can be directly used for judging, and the signals are correspondingly given only when the judgment result is obtained.
In addition, a human body sensing device such as an infrared detector, which is disclosed in the prior art, may be provided in the vehicle, and the presence or absence of a person in the vehicle may be determined by the human body sensing device, so as to provide the electric signal. The judgment can also be performed by detecting whether the automobile is moving, for example, when the automobile is moving, people are inevitably in the automobile, and when the automobile is not moving, people are not in the automobile generally, and certainly, the automobile is not absolutely unmanned when the automobile is stopped, but the judgment does not need absolute accuracy, and a certain error can exist. The specific detection and judgment mode can be flexibly set based on the prior art, and is not described herein too much.
Further, the refrigerator 100 delays to set a time length when receiving the second electrical signal, enters the second state when not receiving the first electrical signal all the time during the delay, and continues to maintain the first state when receiving the first electrical signal within the delay time.
The setting can avoid directly entering the second state to influence the personnel in the automobile when the traffic lights of the automobile and the like stop. The delay time can be flexibly set, such as 60 seconds, 30 seconds and the like.
In addition, the method can also be realized by the way that the control terminal 200 transmits the electric signal in a delayed manner. For example, the time delay setting time length when the automobile detects that no person is in the automobile is delayed, the second electric signal is sent to the refrigerator 100 to enable the refrigerator 100 to enter the second state when the time delay period does not detect that a person is in the automobile all the time, and the first electric signal is sent to the refrigerator 100 to enable the refrigerator 100 to keep the first state when the time delay period detects that a person is in the automobile. This also enables the aforementioned functions to be achieved.
Further, the refrigerator 100 automatically switches to the second state while continuously being maintained at the first state setting for a long time. Since the refrigerator 100 has a certain heat preservation time period, and when the heat preservation time period is exceeded, the goods in the refrigerator 100 lose the refrigeration effect, the present embodiment can avoid the loss of the refrigeration effect of the refrigerated goods by automatically entering the setting of the second state after the refrigerator 100 keeps the first state for the set time period. Also, the set time period can be flexibly set, and is not particularly limited herein.
Further, the refrigerator 100 needs to be powered on when it needs to be kept in standby or automatically controlled, and power can be supplied to the vehicle when the control terminal 200 is the vehicle. The power supply can be additionally configured to supply power.
In order to ensure the best noise reduction effect, the first state is preferably set to a standby state, and the second state is preferably an operation state in which cooling is started.
In addition, the first state and the second state may be set to the cooling operation state, and the power of the refrigerator 100 in the second state is higher than that in the first state, thereby ensuring that the noise of the first state is small.
In addition to the above-mentioned automatic control method, a method B may be adopted, specifically, the control terminal 200 switches the refrigerator 100 from the first state to the second state with higher operating noise than the first state for cooling in a manual starting manner when no person is in the set area or no person is in the set time limit. Thus, the refrigerator 100 is manually switched to the second state through the manual starting mode, and obviously, the user should leave the refrigerator or determines that the noise of the refrigerator 100 in the second state does not affect the user, so that the refrigerator 100 has the advantages and is high in practicability.
It can be understood that the refrigerator noise reduction method is suitable for both vehicle-mounted refrigerators and household refrigerators.
In addition, the invention also provides a refrigerator noise reduction system, which comprises:
the refrigerator 100, the refrigerator 100 has a first state and a second state, the refrigerator 100 performs cooling when in the second state, and the working noise is larger than the noise of the refrigerator 100 when in the first state;
the control terminal 200 is electrically connected to the refrigerator 100, and configured to control the refrigerator 100 to switch from the first state to the second state in a set state. The setting of the first state and the second state can refer to the setting of the foregoing embodiment, and the control terminal 200 can be set to the structural form of automatic detection control or manual control according to the foregoing embodiment.
The refrigerator noise reduction system provided by the invention controls the refrigerator 100 to keep the first state when people around the refrigerator 100 are judged, and the refrigerator 100 enters the second state when no people exist, so that a compressor or a compressor bin is not required to be wrapped by a sound absorption material, and a special design for an air channel is not required, and the practicability is high.
The above examples are only preferred embodiments of the present invention, and other embodiments of the present invention are possible. Those skilled in the art can make equivalent changes or substitutions without departing from the spirit of the present invention, and such equivalent changes or substitutions are included in the scope set forth in the claims of the present application.
