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 utility model, as claimed, but is merely representative of selected embodiments of the utility model.
Referring to fig. 1, the present invention provides a noise reduction system for a refrigerator, including a refrigerator 100 and a control terminal 200 electrically connected to the refrigerator 100, wherein the refrigerator 100 has a first state and a second state, the refrigerator 100 performs cooling when in the second state, and the operating noise is greater than the noise of the refrigerator 100 when in the first state, and the control terminal 200 is configured to control the refrigerator 100 to enter the second state from the first state when no one is present.
According to the utility model, the working state of the refrigerator 100 is controlled through the control end 200, the refrigerator 100 is controlled to be in the first state when people exist, and the refrigerator 100 is controlled to be in the second state when no people exist, wherein the first state can be a low-power running state or a standby state, so that the refrigerator 100 can be kept in the first state when people exist, and then is switched to the second state to carry out high-power refrigeration when no people exist, and no people exist around, so that the noise is large and no influence is caused, a compressor or a compressor bin is not required to be wrapped by a sound-absorbing material, and a special design for an air channel is not required, so that the practicability is strong.
When the first state is a standby state, the second state is set to an operating state of cooling start. And when the first state and the second state are both the cooling operation state, the power of the refrigerator 100 in the second state is higher than that in the first state.
In some embodiments, the control terminal 200 is in an automatic control mode, and in particular, the control terminal 200 has an automatic detection function for automatically controlling the refrigerator 100 to switch from the first state to the second state when no person in the set area or no person in the set time limit is detected.
Taking the refrigerator 100 as an on-vehicle refrigerator as an example, the control terminal 200 is correspondingly set as an automobile, and sends a first electric signal to the refrigerator 100 when the automobile detects that a person is 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 no person is 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 is provided with a delay module, configured to set a time duration when receiving a switching signal delay of the control terminal 200, and then switch to the second state. 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, since the refrigerator 100 has only a certain duration of heat preservation capability, for this reason, the refrigerator 100 is configured with a timing module, and the timing module is configured to automatically switch to the second state after the refrigerator 100 is in the first state for a set duration, so as to refrigerate the refrigerator 100 in time.
In addition, the control end 200 may also be configured as a manual start structure, such as a solid key structure to implement state switching.
Further, the refrigerator 100 is provided with a power supply to ensure power supply in a standby state or in the first and second states. When the power supply device is applied to the automobile in the embodiment, the power supply can be supplied through the automobile.
Further, the refrigerator 100 is provided with a cold storage device to extend the heat-retaining time period of the refrigerator 100. The cold accumulation device can be an ice bag or other structures in the prior art.
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.
