Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to solve the problems that the existing noise reduction mode of the intelligent refrigerator requires a user to move to the intelligent refrigerator for operation switching, the process of the switched running mode of the refrigerator is troublesome, and the experience of the user is poor. In a first aspect, the present invention provides a noise reduction control method for an intelligent refrigerator, and referring to fig. 1, the method includes:
s1: acquiring equipment connection information fed back by a router arranged in an area where the intelligent refrigerator is located; the device connection information is used for indicating terminal devices in the area which establish communication connection with the router.
In the embodiment, the intelligent refrigerator and the router are located in the same area, and the same area can be a home, an office and the like.
The device connection information may indicate all terminal devices establishing communication connection with the router in the area, where the terminal devices may be any electrical devices establishing communication connection with the router, the terminal devices may be smart home appliances such as a smart washing machine, a smart television, a smart sound box, and the like, and may also be mobile terminal devices such as a smart phone, a tablet computer, a notebook computer, or a smart watch with a wifi connection function.
S2: generating a mode switching instruction for controlling the intelligent refrigerator according to the equipment connection information; the mode switching instruction instructs the intelligent refrigerator to operate in a noise reduction mode or a non-noise reduction mode; the noise reduction mode is a mode in which the intelligent refrigerator runs at a lower rotating speed than a conventional rotating speed; the non-noise reduction mode is a mode in which the intelligent refrigerator runs at a normal rotating speed.
In this embodiment, whether a person is in an area where the intelligent refrigerator is located may be determined according to the device connection information, and a corresponding mode switching instruction may be generated according to a result of the determination. When the regional someone of intelligence refrigerator place, need the operation of intelligence refrigerator in the mode of making an uproar of falling, promptly with being less than the normal rotational speed operation in the predetermined temperature range, the refrigerating system of intelligence refrigerator can be because of the reduction of rotational speed and the noise abatement this moment, reaches the effect of making an uproar of falling, and when the regional nobody of intelligence refrigerator place, the normal operating of mode of just making an uproar of falling with the non-is made an uproar to intelligence refrigerator.
It should be noted that the normal rotation speed is the rotation speed at which the intelligent refrigerator normally operates within the corresponding ambient temperature range. In the actual operation of the intelligent refrigerator, the normal rotating speed is smaller than the rated rotating speed of the intelligent refrigerator. Since the environment in which the intelligent refrigerator is located may be different, the conventional rotation speed of the intelligent refrigerator is different for different ambient temperatures. Generally, the higher the ambient temperature, the higher the conventional rotational speed. Illustratively, when the ambient temperature T1 is less than or equal to 16 ℃, the rotating speed of a compressor of the intelligent refrigerator is less than 1500rpm, the rotating speed of a refrigeration fan is less than 950rpm, and the rotating speed of a condensation fan is less than 700 rpm.
When the ambient temperature is 32 ℃ or more and T1 is more than 16 ℃, the rotating speed of the running part of the refrigerating system is properly increased according to the corresponding mode. The compressor rotation speed of the intelligent refrigerator is 1500-plus-1850 rpm, the refrigeration fan rotation speed is 950-plus-1150 rpm, and the condensation fan rotation speed is 700-plus-850 rpm.
When the environmental temperature T1 is more than or equal to 43 ℃, each fan component of the intelligent refrigerator operates at a rated rotating speed.
The above is only an exemplary description of the rotating speed of the intelligent refrigerator corresponding to the ambient temperature, and the actual conventional rotating speed can be actually changed according to different models of intelligent refrigerators.
In some embodiments, referring to fig. 3, generating a mode switching instruction for controlling the smart refrigerator according to the device connection information includes:
when at least one terminal device is in communication connection with the router, generating a noise reduction mode switching instruction; the noise reduction mode switching instruction is used for controlling the intelligent refrigerator to be switched to operate in a noise reduction mode. When at least one terminal device is in communication connection with the router, it is indicated that a person is active in the area where the intelligent refrigerator is located, and at this time, the intelligent refrigerator needs to be switched to a noise reduction mode to operate so as to prevent the intelligent refrigerator from generating excessive noise to a user during operation.
The communication relationship of the intelligent refrigerator for acquiring the noise reduction mode switching instruction is described below with reference to the accompanying drawings, and fig. 2 is a communication connection relationship diagram of the intelligent refrigerator, the router, and the mobile terminal. In fig. 2, the terminal device 300 is a smartphone of a certain user, and when the terminal device 300 establishes a communication connection with the router 200, the router 200 feeds back device connection information, where the device connection information includes related information of the terminal device 300, such as a name, a connection duration, and a connection signal strength of the terminal device 300. Because the terminal device 300 is connected to the router 200, a noise reduction mode switching instruction is generated according to the device connection information, and the intelligent refrigerator 100 switches to the noise reduction mode operation after receiving the noise reduction mode switching instruction.
When the terminal equipment is not in communication connection with the router, generating a non-noise reduction mode switching instruction; and the non-noise reduction mode switching instruction is used for controlling the intelligent refrigerator to be switched to operate in a non-noise reduction mode. Further, after receiving the non-noise reduction mode switching instruction, the intelligent refrigerator is switched to the non-noise reduction mode to operate.
In the embodiment, when the user returns home, the terminal equipment of the user can be connected with the router in the home, and the intelligent refrigerator can be switched into a noise reduction mode according to the steps, so that the noise generated in the operation process is reduced, and the comfort of the user is improved. When the user leaves, the terminal equipment can be disconnected from the router in a communication mode, and at the moment, the intelligent refrigerator can be switched into a non-noise reduction mode according to the steps and normally operates. The user does not have to move to the smart refrigerator to control the mode switching.
In some embodiments, before the step of generating the mode switching instruction for controlling the smart refrigerator according to the device connection information, the method further comprises:
acquiring a first time length for establishing communication connection between the corresponding terminal equipment in the equipment connection information and the router;
if the first time length exceeds a first preset time length, setting the corresponding terminal equipment in the equipment connection information as a fixed connection terminal;
the step of generating a mode switching command for controlling the intelligent refrigerator according to the device connection information includes:
when at least one terminal device is in communication connection with the router and the terminal device is not a fixed connection terminal, generating a noise reduction mode switching instruction;
and when the terminal equipment in communication connection with the router is a fixed connection terminal, generating a non-noise reduction mode switching instruction.
It should be noted that, in the context of the present application, there are smart home appliances fixed in the area where the smart refrigerator is located, and these smart home appliances may maintain a long-time communication connection state with the router. Therefore, the communication connection state of the intelligent household appliances and the router cannot be used as a basis for judging whether people exist in the area. The terminal equipment which is fixedly movable in the area of the intelligent refrigerator and keeps a long-time communication state with the router is defined as a fixed connection terminal.
The first preset time is used for judging whether the terminal equipment is a fixed connection terminal or not, and when the time for establishing communication connection between the terminal equipment and the router exceeds the first preset time, the terminal equipment is set as fixed connection equipment.
In the present embodiment, the device connection information is used only for indicating the terminal device that establishes a communication connection with the router in the area where the refrigerator is located, and does not indicate the fixed connection device. Referring to fig. 4, when at least one terminal device is in communication connection with the router and the terminal device is not a fixed connection terminal, it is described that a person is in an area where the refrigerator is located, and a noise reduction mode switching instruction is generated.
Referring to fig. 5, when all the terminal devices in communication connection with the router are fixed connection terminals, it is indicated that no one is moving in the area where the intelligent refrigerator is located, and a plurality of fixed connection devices are located in the area where the intelligent refrigerator is located, at this time, a non-noise reduction mode switching instruction is generated.
Because there are situations where the user is in the area where the intelligent refrigerator is located for a long time, for example, the user is located at home for a long time, and in the case where the router is not powered off, the terminal device used by the user and the router establishing communication connection may also be set as a fixed connection terminal. In this embodiment, in order to distinguish whether the terminal device establishing the long-time communication connection with the router is a terminal device of a user or an electrical device such as an intelligent home electrical appliance, it may be determined whether the terminal device is a fixed connection terminal through statistics of connection time duration of one or more days. For example, the first preset time period of each day is set to be 16-24 hours, and the terminal equipment with the communication connection time period of each day being 16-24 hours is set as the fixed connection equipment. Or the preset total time of seven days is set as 100 hours, and the terminal with the communication connection time of 100 hours or more in the time of seven days is set as the fixed connection equipment.
Because the user will go home and go out continuously, the number of times of connection with the router will increase as the number of times of entering and exiting increases for the terminal device carried by the user. However, for a terminal device fixed in the area where the refrigerator is located, since it is not necessary to leave the area, disconnection from the router does not occur or rarely occurs. In some embodiments, the connection frequency of the terminal device and the router may also be used as a criterion for determining whether the terminal device is a fixed connection device. For example, when the number of connections of the terminal device within seven days is less than five, the terminal device is set as a fixed connection terminal.
It should be noted that the above embodiments are only exemplary, and in practical applications, the first preset time duration or the preset connection times may be set according to practical situations.
In some embodiments, before generating the mode switching instruction for controlling the smart refrigerator according to the device connection information, the method further includes:
acquiring first signal strength of communication connection between the corresponding terminal equipment in the equipment connection information and the router;
when the first signal is smaller than or exceeds a first preset signal intensity, defining the corresponding terminal equipment in the equipment connection information as a low-signal terminal;
the step of generating a mode switching command for controlling the intelligent refrigerator according to the device connection information includes:
when at least one terminal device is in communication connection with the router and the terminal device is not a low-signal terminal, generating a noise reduction mode switching instruction;
and when the terminal equipment in communication connection with the router is all low-signal terminals, generating a non-noise reduction mode switching instruction.
In this embodiment, whether the user is located in an area where noise emitted by the intelligent refrigerator can affect is determined according to the signal strength of the connection between the terminal device and the router. If the first signal intensity of the corresponding terminal device connected with the router is smaller than the first preset signal intensity in the obtained device connection information, it is indicated that the position of the terminal device is far away from the router and the area where the intelligent refrigerator is located, and the terminal device is not affected by noise emitted by the intelligent refrigerator. Such terminal devices are defined as low signal terminals. When any terminal equipment which is not a low-signal terminal is in communication connection with the router, it is indicated that people are in the area where the intelligent refrigerator is located, and a noise reduction mode switching instruction is generated. When the terminal devices establishing the communication connection are all low-signal terminals, it is indicated that the positions of the terminal devices existing in the area or located at a certain distance from the area are not affected by the noise of the intelligent refrigerator, and a non-noise reduction mode switching instruction is generated.
Referring to fig. 6, there are three terminal devices and a router that establish a communication connection relationship, where the connection signal strength of the first device terminal is two lattices, the connection signal strength of the second device terminal is three lattices, and the connection signal strength of the third device terminal is four lattices; in this embodiment, the terminal devices with two signal strengths and less than two signal strengths are defined as low-signal devices. The first device terminal is defined as a low signal terminal in the device connection information.
According to the embodiment, the intelligent refrigerator can be automatically switched to operate in a corresponding mode according to the signal intensity of the connection between the terminal equipment and the router, so that a user is not influenced by noise.
In some embodiments, the method further comprises:
acquiring the ambient temperature of the external environment of the intelligent refrigerator;
and respectively determining a noise reduction rotating speed range when the intelligent refrigerator operates in the noise reduction mode and a non-noise reduction rotating speed range when the intelligent refrigerator operates in the non-noise reduction mode according to the environment temperature.
Further, the method further comprises:
and when the environment temperature changes, adjusting the noise reduction rotating speed range and the non-noise reduction rotating speed range in a direct proportion relation.
In this embodiment, the intelligent refrigerator operates at a rotation speed suitable for the corresponding temperature. When the ambient temperature is higher, the refrigerating system of the intelligent refrigerator can be operated at a higher rotating speed.
It should be noted that the operation of the intelligent refrigerator at the corresponding rotation speed refers to the operation rotation speed of the refrigeration system component in the intelligent refrigerator, and in this embodiment, the refrigeration system component of the intelligent refrigerator mainly includes a compressor, a refrigeration fan and a condensation fan.
In some embodiments, when the ambient temperature T1 is less than or equal to 16 ℃, in the noise reduction mode, the rotating speed of the compressor is less than or equal to 1200rpm, the rotating speed of the refrigeration fan is less than 800rpm, and the rotating speed of the condensation fan is less than 600 rpm; in the non-noise reduction mode, the rotating speed of a compressor is less than 1500rpm, the rotating speed of a refrigerating fan is less than 950rpm, and the rotating speed of a condensing fan is less than 700 rpm.
When the ambient temperature is 32 ℃ or more and T1 is more than 16 ℃, the rotating speed of the running part of the refrigerating system is properly increased in the corresponding mode. In the noise reduction mode, the rotation speed of the compressor is 1200 plus 1500rpm, the rotation speed of the refrigeration fan is 800 plus 1000rpm, and the rotation speed of the condensation fan is 600 plus 750 rpm; in the non-noise reduction mode, the rotation speed of the compressor is 1500-1850rpm, the rotation speed of the refrigeration fan is 950-1150rpm, and the rotation speed of the condensation fan is 700-850 rpm.
When the ring temperature is higher than 32 ℃, the corresponding noise reduction mode rotating speed is different, and the details are not described herein.
In some embodiments, the method further comprises:
acquiring a second time length of the intelligent refrigerator running in a non-noise reduction mode;
and if the second time length exceeds a second preset time length, alternately executing and generating the noise reduction mode switching instruction and the non-noise reduction mode switching instruction at intervals of a first preset time.
