[0032] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application.
[0033] The embodiment of the present application provides a control method, which is described with reference toFigure 1 As shown, the method is applied to a refrigeration device, and the method comprises the following steps:
[0034] Step 101, the refrigeration device performs n defrosting operations continuously according to a first time interval within a target time, and in the case that the first defrosting time length of the n defrosting operations is less than or equal to a preset defrosting time length, the time interval corresponding to the time from the end of the n th defrosting operation to the start of the n+1 th defrosting operation is determined as a second time interval.
[0035] Wherein, n is an integer greater than or equal to 1, and the second time interval is greater than the first time interval.
[0036] In the embodiments of the present application, the refrigeration device is a device with refrigeration function, for example, it can be a refrigerator device, and in some application scenarios, it can also be an air conditioner device. The target time can be the running time of the refrigeration device, or the working time of the compressor of the refrigeration device. The first time interval is the time interval between two defrosting operations, which can be obtained by pre-setting or according to the actual application scenario. The preset defrosting time length can be the defrosting time length experience value obtained according to a large number of experiments, or the defrosting experience time length determined according to the actual application scenario.
[0037] When the refrigeration device detects that the first defrosting time length of n continuous defrosting operations is less than or equal to the preset defrosting time length, the time interval to the n+1 th defrosting operation is determined as the second time interval, which is greater than the first time interval, so as to pull apart the time interval and reduce the number of defrosting operations of the refrigeration device.
[0038] Step 102, start timing when the n th defrosting operation ends.
[0039] In the embodiments of the present application, the refrigeration device detects the end of the n th defrosting operation, and performs timing operation, for example, it can be realized by physical timer or virtual timer.
[0040] Step 103, perform the n+1 th defrosting operation when the timing time length is the second time interval.
[0041] In the embodiments of the present application, when the timing time length is the second time interval, the refrigeration device performs the n+1 th defrosting operation, for example, the refrigeration device starts the defrosting device to defrost.
[0042] In the embodiment of the present application, the refrigeration equipment continuously performs n defrosting operations at a first time interval within a target time, and in the case that the first defrosting time of the n defrosting operations is less than or equal to a preset defrosting time, the time interval corresponding to the time from the end of the n th defrosting operation to the start of the n+1 th defrosting operation is determined as a second time interval. The n th defrosting operation is started at the end of the n th defrosting operation, and the n+1 th defrosting operation is performed when the time interval is the second time interval. In this way, when the defrosting time of the n defrosting operations of the refrigeration equipment is less than or equal to the preset defrosting time, the interval of the next defrosting is increased to the second time interval, solving the problem that the refrigeration equipment frequently performs defrosting operations. A method of controlling the interval of the defrosting operation according to the defrosting time is proposed, reducing the number of defrosting operations of the refrigeration equipment, but ensuring the defrosting capacity of the refrigeration equipment, and reducing the energy consumption of the refrigeration equipment.
[0043] Based on the foregoing embodiment, an embodiment of the present application provides a control method, which is applied to a refrigeration equipment, and the method comprises the following steps:
[0044] In step 201, in the case that the refrigeration equipment continuously performs n defrosting operations at a first time interval within a target time, and the first defrosting time of the n defrosting operations is less than or equal to a preset defrosting time, the time interval corresponding to the time from the end of the n th defrosting operation to the start of the n+1 th defrosting operation is determined as a second time interval.
[0045] In the embodiment of the present application, n is an integer greater than or equal to 1, and the second time interval is greater than the first time interval.
[0046] In the embodiment of the present application, the target time can be a natural time corresponding to a year, month, day and hour, or a compressor working time of the refrigeration equipment. When the refrigeration equipment performs defrosting operation, the time from the start to the end of each defrosting operation is recorded to obtain the defrosting time. The refrigeration equipment also counts the number of continuous defrosting operations at the first time interval. When the counted number is n, the relationship between the first defrosting time of the n defrosting operations and the preset defrosting time is compared and analyzed. If the first defrosting time of the n defrosting operations is less than the preset defrosting time, the defrosting interval time is adjusted, that is, the time interval from the end of the n th defrosting operation to the start of the n+1 th defrosting operation is set as the sum of the first time interval and the first adjustment time interval. For example, the first adjustment time interval can be 24 hours. If the target time is a natural time, the refrigeration equipment can be set to perform defrosting operation at 2 o'clock every day. If the target time is related to the working state of the refrigeration equipment, for example, the target time corresponds to the cumulative running time of the compressor, the refrigeration equipment performs defrosting operation every 24 hours of the compressor working time.
[0047] Step 202, start timing when the n-th defrosting operation ends.
[0048] Step 203, perform the n+1-th defrosting operation when the timing duration is the second time interval.
[0049] Based on the foregoing embodiments, in other embodiments of the present application, step 201 can be implemented by steps 201a-201b:
[0050] Step 201a, determine the first adjustment time interval.
[0051] In other embodiments of the present application, the first adjustment time interval can be a time adjustment step value obtained from a large number of experiments, or an empirical time adjustment step value determined according to the actual application scenario.
[0052] Step 201b, determine that the second time interval is the sum of the first time interval and the first adjustment time interval.
[0053] Based on the foregoing embodiments, in other embodiments of the present application, referring to FIG. 2, after the refrigeration equipment performs step 203, it is further used to perform steps 204-206: Figure 2
[0054] Step 204, count the second defrosting duration of the n+1-th defrosting operation.
[0055] In the embodiments of the present application, the defrosting duration of the n+1-th defrosting operation is counted and recorded to obtain the second defrosting duration.
[0056] After the refrigeration equipment performs step 204, it can choose to perform step 205, and can also choose to perform step 206. If the second defrosting duration is less than or equal to the preset defrosting duration, step 205 is selected, and if the second defrosting duration is greater than the preset defrosting duration, step 206 is selected.
[0057] Step 205, if the second defrosting duration is less than or equal to the preset defrosting duration, determine that the time interval corresponding to the end of the n+1-th defrosting operation to the start of the n+2-th defrosting operation is the second time interval.
[0058] In the embodiments of the present application, when the second defrosting duration is less than or equal to the preset defrosting duration, the time interval corresponding to the execution of the next defrosting operation, i.e., the n+2-th defrosting operation, is maintained as the second time interval, so that the defrosting interval is increased, the defrosting frequency is reduced, and the resource consumption of the refrigeration equipment is reduced.
[0059] Step 206, if the second defrosting duration is greater than the preset defrosting duration, determine that the time interval corresponding to the end of the n+1-th defrosting operation to the start of the n+2-th defrosting operation is the first time interval.
[0060] In the embodiment of the present application, when the second defrosting duration is greater than the preset defrosting duration, the time interval for the next defrosting operation is the first time interval, the time interval is shortened, the defrosting efficiency is improved, and the refrigeration function of the refrigeration equipment is ensured. This is repeated, and the defrosting interval is dynamically adjusted according to the defrosting duration of the defrosting operation, which effectively ensures the defrosting efficiency of the refrigeration equipment, reduces the energy consumption of the refrigeration equipment, and enriches the defrosting control technology.
[0061] Based on the foregoing embodiment, in other embodiments of the present application, referring to FIG. 7, the refrigeration equipment is further configured to perform steps 207-208: Figure 3
[0062] Step 207, when the timing duration is the second time interval, after performing the defrosting operation, determining m as the difference between n and the number of adjustment steps.
[0063] In the embodiment of the present application, the number of adjustment steps can be an empirical value set according to a large number of experiments, or an empirical value set by the user according to actual needs, or an empirical value determined according to the actual application scenario. When the timing duration is the second time interval, after performing the corresponding defrosting operation, the number of times counted continuously according to the first time interval is determined, denoted as m, and determined as m=n-number of adjustment steps. The number of adjustment steps can be an empirical value obtained from a large number of experiments, and the number of adjustment steps can be different in each adjustment process. The number of adjustment steps can be an integer greater than or equal to 0.
[0064] Step 208, after updating n to m, performing the step “when the refrigeration equipment performs n times of defrosting operation continuously according to the first time interval within the target time, and the first defrosting duration of the n times of defrosting operation is less than or equal to the preset defrosting duration, determining that the time interval corresponding to the n times of defrosting operation from the end of the n times of defrosting operation to the start of the n+1 times of defrosting operation is the second time interval”.
[0065] In the embodiment of the present application, after determining m, the value of n is updated to the value of m, and then the steps are repeatedly performed from step 201, and the corresponding defrosting interval is continuously adjusted.
[0066] Based on the foregoing embodiment, in other embodiments of the present application, the refrigeration equipment is further configured to perform at least one of the following steps:
[0067] Step 209, determining the first time interval based on the environmental parameters of the space where the refrigeration equipment is located.
[0068] In the embodiments of the present application, the refrigeration equipment obtains the environmental parameters of the space where the refrigeration equipment is located. The environmental parameters can be collected by an environmental parameter acquisition device independent of the refrigeration equipment but in communication connection with the refrigeration equipment, or can be collected by an environmental parameter acquisition device arranged on the refrigeration equipment.
[0069] The first time intervals can be calculated by an empirical calculation formula of the environmental parameters and the time intervals, or can be determined by the parameter values of different environmental parameters corresponding to different first time intervals determined in advance, for example, a relationship list.
[0070] In step 210, n is determined based on the environmental parameters.
[0071] In the embodiments of the present application, the value of n can also be determined by the environmental parameters of the space where the refrigeration equipment is located. The relationship between the corresponding n value and the environmental parameters can be an empirical calculation formula or a relationship list.
[0072] In step 211, m is determined based on the environmental parameters.
[0073] In the embodiments of the present application, the value of m can be determined by the environmental parameters of the space where the refrigeration equipment is located. The relationship between the corresponding n value and the environmental parameters can be an empirical calculation formula or a relationship list.
[0074] In step 212, the preset defrosting time length is determined based on the environmental parameters.
[0075] In the embodiments of the present application, the preset defrosting time length can be determined by the environmental parameters of the space where the refrigeration equipment is located. The relationship between the corresponding preset defrosting time length and the environmental parameters can be an empirical calculation formula or a relationship list.
[0076] In step 213, the first adjustment time interval is determined based on the environmental parameters.
[0077] In the embodiments of the present application, the first adjustment time interval can be determined by the environmental parameters of the space where the refrigeration equipment is located. The relationship between the corresponding first adjustment time interval and the environmental parameters can be an empirical calculation formula or a relationship list.
[0078] Based on the foregoing embodiments, in other embodiments of the present application, the maximum value of n is 3, the minimum value of m is 0, and the maximum value of m is 2.
[0079] Based on the foregoing embodiments, in other embodiments of the present application, the environmental parameters include one or more of the following parameters: an environmental temperature parameter, an environmental humidity parameter.
[0080] In the embodiments of the present application, the environmental parameter can be an environmental temperature parameter, an environmental humidity parameter, or an environmental temperature parameter and an environmental humidity parameter. The specific parameters included in the environmental parameter can be determined according to the actual application scenario, and are not limited here.
[0081] Based on the foregoing embodiments, in other embodiments of the present application, referring to FIG. 13, the refrigeration equipment is further configured to perform steps 214-217. Figure 4
[0082] Step 214, count the number of door openings and the door opening duration in the third time interval.
[0083] The third time interval is the first time interval or the second time interval.
[0084] In the embodiments of the present application, the number of times the door of the refrigeration equipment is opened in each time interval is counted, the door opening duration of each door opening is counted, and then the total door opening duration in the time interval is calculated.
[0085] Step 215, determine the second adjustment time interval based on the number of door openings and the door opening duration.
[0086] In the embodiments of the present application, the second adjustment time interval can be determined from the corresponding relationship list according to the number of door openings and the door opening duration, or can be calculated by using an empirical calculation formula.
[0087] Step 216, determine that the adjacent time interval after the third time interval is the difference between the third time interval and the second adjustment time interval.
[0088] Step 217, update the first time interval to the fourth time interval.
[0089] Based on the foregoing embodiments, the present application provides a refrigeration equipment, wherein the evaporator is an important component of the refrigeration equipment, and the evaporator mainly provides cold energy to the chamber of the refrigeration equipment. As the refrigeration time increases, the amount of frost on the evaporator gradually increases, and as the amount of frost increases, the refrigeration efficiency of the evaporator gradually decreases. Therefore, defrosting of the evaporator is needed after a period of refrigeration, and at this time, the defrosting heater can be used to heat and defrost the evaporator. Correspondingly, the embodiments of the present application provide an application embodiment for controlling the defrosting interval time of the refrigeration equipment. Taking a refrigerator as an example, the specific implementation process can be as follows:
[0090] Step a11, the refrigerator normally refrigerates.
[0091] Step a12, the refrigerator acquires the environmental temperature and the environmental humidity, and looks up the table to obtain the defrosting interval Tws corresponding to the environmental temperature and the environmental humidity.
[0092] Step a13, during the operation of the refrigerator, the running time Tb of the refrigerator is continuously monitored.
[0093] Step a14, when Tb is greater than or equal to Tws, the refrigerator stops the refrigeration work, starts the defrosting heater to perform the defrosting operation, and records the defrosting time ts1 from starting the defrosting heater to stopping the defrosting heater.
[0094] Wherein, after the defrosting of the refrigerator is completed, the refrigeration equipment is normally refrigerated and operated until the next defrosting, and the steps a12-a14 are repeated until the n times of execution, and the defrosting time ts1, ts2, …, tsn is obtained.
[0095] Wherein, n is a natural number, and the value range can be 1 to 3, including 1 and 3.
[0096] Step a15, when ts1, ts2, …, tsn is less than or equal to the time t, the next defrosting interval is determined as Tws+T.
[0097] Wherein, after the refrigerator executes the step a15, referring to Figure 5 , step a16-a18 is selected to be executed, or referring to Figure 6 , step a16 is selected to be executed, and step a12 is repeatedly executed.
[0098] Step a16, when the running time Tb of the refrigerator is greater than or equal to Tws+T, the refrigerator stops refrigeration, the defrosting heater starts to work to perform the defrosting operation, and the defrosting operation time ts(n+1) is recorded.
[0099] Wherein, after the refrigerator executes the step a16, step a17 or step a18 can be selected to be executed.
[0100] Step a17, when ts(n+1) is less than or equal to the time t, the next defrosting interval is determined to continue to be Tws+T.
[0101] Wherein, after the refrigerator executes the step a17, the steps a16-a18 can be repeatedly executed to perform the continuous determination process of the defrosting interval.
[0102] Step a18, when ts(n+1) is greater than the time t, the next defrosting interval is determined to be Tws.
[0103] Wherein, after the refrigerator executes the step a18, the steps aa12-a18 are repeatedly executed to realize the continuous determination process of the defrosting interval.
[0104] Further, in some application scenarios, after the refrigerator performs step a16, when ts(n+1) is less than or equal to the time length t, the next time interval is determined to be the first time interval, and then when the defrosting time length of the continuous n-k times of defrosting operation is less than or equal to the time length t, the defrosting interval is adjusted to Tws+T, and the defrosting time interval is adjusted in this way. Wherein, k can be determined according to the ambient temperature and / or ambient humidity of the environment in which the refrigerator is located, k can take different values and is a natural number, and can take values in the range of 0 to 2, including 0 and 2, k corresponds to the aforementioned number of adjustment steps.
[0105] Further, n can be determined according to the ambient temperature and / or ambient humidity of the environment in which the refrigerator is located;
[0106] Further, t can be determined according to the ambient temperature and / or ambient humidity of the environment in which the refrigerator is located;
[0107] Further, T can be determined according to the ambient temperature and / or ambient humidity of the environment in which the refrigerator is located;
[0108] Further, the next time interval can also be adjusted according to the number of door openings N and the total time length t1 of door opening of the refrigerator in the previous time interval, for example, an empirical formula T2=f(N,t1) can be used to calculate T2 based on N and t1, and then T2 is subtracted from the previous time interval to obtain the next time interval.
[0109] is a natural time;
[0110] Further, the foregoing method can be applied to scenarios that do not consider the working state of the compressor of the refrigeration system of the refrigerator, but only consider the change of time, and can also be applied to scenarios that only perform according to the running time length of the compressor, that is, the foregoing is related to the running state of the compressor.
[0111] It should be noted that the descriptions of the same steps and contents in this embodiment and other embodiments can refer to the descriptions in other embodiments, and will not be repeated here.
