Detailed Description
Fig. 1 is a schematic view of a refrigerator 10 according to one embodiment of the present invention, and fig. 2 is a schematic block diagram of the refrigerator 10 according to one embodiment of the present invention.
The refrigerator 10 may generally include the tilt sensor 200 and the control device 400, and may further include a refrigeration system. The control device 400 may include a processor 410 and a memory 420.
The refrigeration system may be a compression refrigeration system. The refrigeration system may include a compressor, a condenser, a throttling device, and an evaporator. When the refrigerating system is in a starting state, under the action of the compressor, the refrigerant is subjected to exothermic condensation when flowing through the condenser, and is subjected to endothermic evaporation when flowing through the evaporator. The refrigeration system may utilize the refrigerant to absorb heat in the evaporator to undergo a phase change to cool the storage compartment of the refrigerator 10.
The tilt sensor 200 may be provided on the cabinet 120 or the door of the refrigerator 10, for example, may be provided at an outer side of the cabinet 120 or the door. The words "inner" and "outer" are used to refer to directions with respect to the actual usage state of the refrigerator 10, and may refer to a side facing the working environment of the refrigerator 10. The tilt sensor 200 is used to detect a tilt angle of the refrigerator 10 with respect to a vertical direction (hereinafter may be simply referred to as "tilt angle of the refrigerator 10"). The refrigerator 10 is in a normal upright state when the inclination angle of the refrigerator 10 with respect to the vertical direction is 0, and is in an inclined state when the inclination angle of the refrigerator 10 with respect to the vertical direction is not 0. The "inclined state" herein may include any angle when the inclination angle is not 0. For example, when the refrigerator 10 is in the "lying state", an inclination angle thereof with respect to the vertical direction may be 90 °, and when the refrigerator 10 is in the "standing state", an inclination angle thereof with respect to the vertical direction may be 180 °.
The tilt sensor 200 has a battery for supplying power to the tilt sensor 200. In the case where the battery supplies power to the tilt sensor 200, the tilt sensor 200 may detect the tilt angle of the refrigerator 10 once at preset time intervals. The time interval may reflect the detection accuracy of the detection result of the tilt sensor 200 in the set period of time, and may be set to any value in the range of 0.1 to 60s, for example, but is not limited thereto. By arranging the independent power supply battery for the inclination sensor 200, the inclination sensor 200 can comprehensively collect the inclination angle of the refrigerator 10 in the whole carrying process of the refrigerator 10, thereby ensuring the accuracy of detection record and solving the problem that the refrigerator 10 in the carrying process cannot be connected with an external power supply.
The tilt sensor 200 of the present embodiment may be in communication connection with the control device 400 of the refrigerator 10 in advance, so that the control device 400 may be driven to send a query request to the tilt sensor 200 after the refrigerator 10 is powered on, so as to obtain detection data of the tilt sensor 200. For example, a communication circuit may be connected between the tilt sensor 200 and the control device 400.
The control device 400 may be disposed within the cabinet 120 of the refrigerator 10. The control device 400 of the present embodiment may be a main control board. A control program 421 is stored in the memory 420 of the control device 400, and the control program 421 is used to implement the control method of the refrigerator 10 according to any one of the following embodiments when executed by the processor 410. The processor 410 may be a Central Processing Unit (CPU), or a digital processing unit (DSP), or the like. The memory 420 is used to store programs executed by the processor 410. Memory 420 may be any medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer, but is not limited to such. Memory 420 may also be a combination of various memories. Since the control program 421 realizes the processes of the following method embodiments when executed by the processor 410, and the same technical effects can be achieved, the description is omitted here for avoiding repetition.
Fig. 3 is a schematic view of a control method of the refrigerator 10 according to an embodiment of the present invention. The control method of the present embodiment is particularly suitable for a refrigerator 10 in which a target interactive user (i.e., a user of the refrigerator 10, simply referred to as "user") who is carried to the refrigerator 10 designates a work environment, such as a refrigerator 10 newly purchased or a refrigerator 10 which is returned to a factory for repair and re-carried to the user designating a work environment. The control method may generally include:
in step S302, a detection record of the tilt sensor 200 is acquired, and a detection result of the tilt sensor 200 in a set period of time is recorded in the detection record.
Step S304, the cooling prohibition time period of the refrigerator 10 is calculated from the detection record.
In step S306, the refrigeration system of the refrigerator 10 is controlled according to the refrigeration prohibition period, so that the refrigeration system is in a stopped state during the refrigeration prohibition period.
With the above method, in this embodiment, by obtaining the detection record of the inclination sensor 200, the refrigeration inhibition duration of the refrigerator 10 is calculated according to the detection record, and the refrigeration system of the refrigerator 10 is controlled according to the refrigeration inhibition duration, so that the refrigeration system is in a shutdown state in the refrigeration inhibition duration, so that the refrigerator 10 of this embodiment can automatically determine the refrigeration inhibition duration, and provide delay protection for the compressor according to the refrigeration inhibition duration, thereby improving the intelligentization degree of the refrigerator 10.
By calculating the refrigerating prohibition time according to the detection record and controlling the refrigerating system according to the calculated refrigerating prohibition time, the standing time of the refrigerating system can be set according to the actual inclination condition, and the refrigerator 10 can refrigerate in time on the premise of providing delay protection for the compressor.
In the above step S302, the size of the set time period may be set according to the type of the compressor of the refrigerator 10, and may be any value ranging from 60 to 180 minutes, for example. The detection record records the detection result of the tilt sensor 200 in the set period of time may refer to the detection result in the set period of time before the control device 400 sends the query instruction to the tilt sensor 200. The detection result may include a plurality of inclination angles of the refrigerator 10 detected by the inclination sensor 200 at different times within a set period of time, and the detection result includes numerical information of the inclination angle and time information corresponding to the numerical value of the detected inclination angle.
Prior to the above step S302, the control method may further include: whether the refrigerator 10 is in the energized state is detected, and in the case where the refrigerator 10 is in the energized state, a step of acquiring a detection record of the tilt sensor 200 is performed.
When the wire-terminal of the refrigerator 10 is connected to the outlet of the external power source, i.e., the external power source is connected, it is in an energized state. By detecting whether the refrigerator 10 is in the power-on state, a query request can be sent to the tilt sensor 200 immediately after the refrigerator 10 is powered on to acquire the detection record of the tilt sensor 200, so that timeliness of the acquisition process is improved, whether the refrigerator 10 is in the refrigeration inhibition state can be analyzed in time according to the detection record, and a response can be timely made.
The step S304 may include: acquiring a plurality of preset inclination angle ranges and reference coefficients corresponding to each inclination angle range, determining the inclination time of the refrigerator 10 in each inclination angle range according to the detection record, and calculating the refrigeration inhibition time according to the reference coefficients and the inclination time corresponding to each inclination angle range.
The plurality of inclination angle ranges and the reference coefficient corresponding to each inclination angle range are preset values, and can be preset according to the model of the compressor. For example, the predetermined plurality of tilt angle ranges may be 0 to 30 ° (not including 0 °), 30 to 60 ° (not including 30 °), 60 to 180 ° (not including 60 °), and the reference coefficients corresponding to the respective tilt angle ranges may be any values within the range of 0.1 to 0.7,0.3 to 0.8,0.5 to 1, for example, 0.6, 0.7, and 0.8, respectively. The above is exemplified only for the case where the inclination angle ranges are three, and the inclination angle ranges of the present embodiment should not be construed as being limited to only three.
For the tilting time period of the refrigerator 10 in each tilt angle range, for example, if the tilting angle of the refrigerator 10 in the set time period is in the tilt angle range of 0 to 30 °, the tilting time period of the refrigerator 10 in the tilt angle range of 0 to 30 ° is the total time period of the set time period, and the tilting time periods in the tilt angle ranges of 30 to 60 ° and 60 to 180 ° are both 0. If the set time period is 120min, and the time length of the refrigerator 10 with the inclination angle in the range of 0-30 ° is 60min and the time length of the refrigerator with the inclination angle in the range of 30-60 ° is 60min, the time length of the refrigerator 10 with the inclination angle in the range of 0-30 ° is 60min, the time length of the refrigerator with the inclination angle in the range of 30-60 ° is 60min, and the time length of the refrigerator with the inclination angle in the range of 60-180 ° is 0.
Since the handling process of the refrigerator 10 is dynamic and continuous, the refrigerator 10 may have a plurality of different inclination angles in a set period of time. By presetting a plurality of inclination angle ranges and correspondingly presetting reference coefficients for each inclination angle range, in the process of calculating the refrigerating prohibition time, the inclination time of the refrigerator 10 in each inclination angle range is determined according to the detection record, and the refrigerating prohibition time is calculated according to the reference coefficients and the inclination time corresponding to each inclination angle range, so that the refrigerating prohibition time is conveniently and accurately calculated according to the actual inclination condition of the refrigerator 10, the accuracy of the calculation process is improved, and the problem of 'approximate total' existing when the standing time of the refrigerator 10 is determined is reduced or avoided.
The step of determining the tilting time period of the refrigerator 10 in each tilting angle range according to the detection record may include: a change curve of the change of the inclination angle of the refrigerator 10 with respect to the vertical direction over time in a set period of time is acquired, and the inclination time of the refrigerator 10 in each inclination angle range is determined according to the change curve. The change curve may be plotted in a plane rectangular coordinate system, the abscissa may be time, and the ordinate may be an inclination angle of the refrigerator 10.
For example, in determining the inclination time of the refrigerator 10 in each inclination angle range according to the change curve, the value ranges of the independent variables of the change curve in the respective inclination angle ranges of 0 to 30 °,30 to 60 °,60 to 180 ° may be calculated, and the inclination time of the refrigerator 10 in each inclination angle range may be obtained according to the value ranges of the independent variables.
The step of calculating the refrigeration prohibiting period according to the reference coefficient and the inclination period corresponding to each inclination angle range may include: according to the formulaCalculating the refrigerating prohibition time length, wherein T represents the refrigerating prohibition time length and k i Representing a reference coefficient corresponding to a range of tilt angles, a i Represent and tilt angle range (where tilt angle range means and k i The tilt angle range to which this reference coefficient corresponds), n represents the number of preset tilt angle ranges.
For example, if the set time period is 120min, the reference coefficients corresponding to the inclination angle ranges of 0 to 30 °,30 to 60 °,60 to 180 ° are 0.6, 0.7, and 0.8, respectively, the inclination angles of the refrigerator 10 are 0 to 30 °,30 to 60 °, and the inclination durations in the 60 to 180 ° ranges of 30min,60min, and 30min, respectively, the cooling duration=0.6x30+0.7x60+0.8x30=84 min is prohibited.
By using the method, the refrigerating prohibition time length is calculated by using the formula, and the calculating method of the refrigerating prohibition time length is simplified. The refrigerating prohibition time of the refrigerator 10 can be determined by analyzing the detection record of the inclination sensor 200, and the method is simple and convenient, has simple control logic and high accuracy, so that the refrigerator 10 of the embodiment can provide delay protection for the compressor by using a simple and effective method.
The step S306 may include: whether the refrigerator 10 is in the refrigerating prohibition state is judged according to the refrigerating prohibition time length, if so, the time-delay refrigerating mode is started, the refrigerating system is configured to be in a stop state in the time-delay refrigerating mode, and if not, the time-delay refrigerating mode is not started.
The step of judging whether the refrigerator 10 is in the cooling prohibition state according to the cooling prohibition time period may include: judging whether the refrigerating prohibition time is greater than a preset time threshold, if yes, determining that the refrigerator 10 is in a refrigerating prohibition state, and if not, determining that the refrigerator 10 is not in the refrigerating prohibition state. The time period threshold may be set according to the model of the compressor, and may be any value in the range of 0 to 10 minutes, for example, but is not limited thereto. The time length threshold value of the embodiment may be 0, and when the refrigerating time length is prohibited to be greater than 0, the time delay refrigerating mode is started, so long as the refrigerator 10 is inclined in the carrying process, time delay protection can be provided for the compressor, and the operation reliability of the refrigerator 10 is improved.
By using the method, the refrigerating prohibition time is automatically determined, whether the refrigerator 10 is in the refrigerating prohibition state is judged according to the refrigerating prohibition time, and the delayed refrigerating mode is started under the condition that the refrigerator 10 is in the refrigerating prohibition state, so that the refrigerator 10 can be installed and debugged without waiting for standing time, the installation and debugging efficiency is improved, the labor cost is saved, and the installation and debugging cost of the refrigerator 10 is reduced.
The step of enabling the time-lapse cooling mode may comprise: and determining that the refrigeration system is in a shutdown state, and sending a delay instruction to the refrigeration system to instruct the refrigeration system to maintain the shutdown state within the refrigeration inhibition period. In determining that the refrigeration system is in the shutdown state, the control device 400 may query a flag bit of the compressor, where the flag bit of the compressor may include a shutdown flag bit corresponding to the shutdown state and a start flag bit corresponding to the start state, and if the flag bit of the compressor is the shutdown flag bit, the refrigeration system may be determined to be in the shutdown state. In some alternative embodiments, if the refrigerator 10 leaves the factory default compressor flag is a start flag, the control apparatus 400 may modify the start flag to a stop flag.
In the step of sending the delay instruction to the refrigeration system, the delay instruction may be sent to the refrigeration system according to the refrigeration prohibition time, for example, the control device 400 outputs the delay instruction to the compressor of the refrigerator 10, where the delay instruction may carry information of the refrigeration prohibition time, so that the compressor is not started in the refrigeration prohibition time. In the process that the control device 400 sends the delay instruction to the compressor of the refrigerator 10, the control device 400 may set the maintenance duration of the stop flag of the compressor, for example, the maintenance duration of the stop flag may be set to the refrigerating prohibition duration.
The refrigerator 10 of the present embodiment may further include a timer for providing a timing control function, and may include, for example, starting timing, stopping timing, continuing timing, and the like. The timer may be pre-established with the control device 400. After the step of starting the time-lapse cooling mode, the control method may further include: starting a timer and starting timing, and after the timing reaches the refrigerating prohibition time, sending a starting instruction to the refrigerating system to instruct the refrigerating system to switch from the stopping state to the starting state. In the case that the duration of the refrigerating system kept in the stopped state reaches the refrigerating prohibition duration, the refrigerating system can be automatically started by sending a start-up instruction to the refrigerating system, so that the refrigerator 10 can quickly and timely perform a normal refrigerating function.
After the step of starting the time-lapse cooling mode, the control method may further include: the distribution mode is initiated so that the refrigerator 10 establishes a communication connection with the terminal equipment in its operating environment. The network configuration mode may refer to a mode that enables the refrigerator 10 to establish communication connection with a terminal device in a working environment, for example, the refrigerator 10 may establish communication connection with a specific application program in the terminal device in the network configuration mode, and a user may send a control instruction to the refrigerator 10 by using the application program, or may query information such as an operation parameter, an equipment parameter, and the like of the refrigerator 10. The step of starting the distribution mode may be performed simultaneously with the step of starting the timer.
The step of initiating a distribution mode may include: the wireless access point of the refrigerator 10 in the working environment is determined, and a network allocation request signal is output to the working environment to establish communication connection with the terminal device in the working environment.
The refrigerator 10 may be pre-accessed to a wireless access point in an operating environment to access a wireless local area network. The refrigerator 10 may output a network allocation request in a broadcast manner, and the network allocation request may carry information such as a MAC address of the refrigerator 10. The terminal device in the operating environment may access the same wireless local area network as the refrigerator 10 in the operating environment. The terminal device may respond to the network allocation request and establish a communication connection with the refrigerator 10 according to information carried by the network allocation request. As for the specific manner of establishing the communication connection, those skilled in the art should easily understand the present embodiment, and detailed description thereof will be omitted herein.
The present embodiment improves the control logic of the refrigerator 10 so that it can delay the start of the compressor. By using the method, the delayed refrigeration mode is started, so that the network distribution process of the refrigerator 10 does not need to consider whether the compressor reaches the starting condition, which is beneficial to improving the flexibility of starting the network distribution mode of the refrigerator 10.
