The specific embodiment of the refrigeration equipment of the present invention is substantially the same as the following embodiments of the refrigeration equipment defrosting control method, and is not described herein again.
Referring to fig. 2, fig. 2 is a schematic flow chart of an embodiment of a defrosting control method for refrigeration equipment according to the present invention, and the defrosting control method for refrigeration equipment provided in this embodiment includes the following steps:
step S10, acquiring the working voltage of the refrigeration equipment under the condition that the refrigeration equipment reaches a defrosting exit condition;
for purposes of describing the embodiments in detail, the refrigeration appliance is illustrated as a refrigerator, it being understood that the refrigeration appliance may be a refrigerator, freezer, or other appliance capable of refrigerating or freezing food or goods. During the operation of the refrigerator, if the operation state of the refrigerator meets the defrosting condition, the refrigerator starts defrosting, specifically, a certain temperature sensor is arranged in the refrigerator, and can detect the temperature of the refrigerating chamber of the refrigerator, for example, the temperature of the refrigerating chamber and the temperature of the freezing chamber of the refrigerator. When the temperature of the refrigerating chamber of the refrigerator reaches a certain temperature, the defrosting heater of the refrigerator starts to be powered on to work, so that the refrigerator enters a defrosting state. Optionally, when the temperature of the refrigeration compartment of the refrigerator is less than 1 degree, it indicates that the refrigeration compartment of the refrigerator may be frosted, and the defrosting heater starts to be powered on. The method comprises the steps of acquiring the working time of the defrosting heater and the temperature of a refrigerating chamber of the refrigerator in real time in the working process of the defrosting heater, and judging whether the refrigerator reaches a defrosting exit condition or not according to the working time of the defrosting heater and the temperature of the refrigerating chamber of the refrigerator.
It should be noted that, when the refrigerator reaches the defrosting exit condition, the determination process of whether to delay defrosting can be directly performed according to the magnitude of the working voltage and the rated voltage, and further, the working voltage of the refrigerator can be obtained first, and then whether to perform the power-off process on the defrosting heater is determined according to the magnitude of the working voltage.
And step S20, controlling the defrosting heater to work in a delayed mode when the working voltage of the refrigeration equipment is smaller than the rated voltage.
It is easy to understand that, in this embodiment, the rated voltage of the refrigerator is preset, that is, the voltage input that should be obtained when the refrigerator is in a normal operating state, and in addition, the refrigerator is further provided with a voltage detection device, which can obtain the current operating voltage of the refrigerator in real time. And comparing the obtained working voltage of the refrigerator with a preset rated voltage of the refrigerator, and determining that the refrigerator is in a low-voltage condition if the working voltage is less than the rated voltage.
When the refrigerator is in a low voltage condition, the output power of the defrosting heater is greatly reduced due to low input voltage, specifically, the input power of the defrosting heater is reduced to 80% or lower of the rated power, so that the defrosting performance of the refrigerator is remarkably reduced, and ice blockage of refrigerator devices such as a drain pipe and an evaporator in the refrigerator is easily caused. Therefore, when the refrigerator is in a low-voltage condition, the defrosting heater is controlled to work in a delayed mode, and the defrosting heater can continuously defrost the refrigerator.
In the embodiment, the working voltage of the refrigeration equipment is obtained under the condition that the refrigeration equipment reaches the defrosting exit condition; the working voltage of the refrigeration equipment is less than the rated voltage, and the defrosting heater is controlled to work in a delayed mode. The working voltage of the refrigeration equipment is detected to judge whether the refrigeration equipment is in a low-voltage environment, and when the refrigeration equipment is in the low-voltage environment, the defrosting heater is controlled to work in a delayed mode, so that the refrigeration equipment enters a defrosting ending state in a delayed mode, and the defrosting effect of the refrigeration equipment is improved.
Further, referring to fig. 3, fig. 3 is a detailed flowchart of the step of controlling the delay operation of the defrosting heater according to the present invention, wherein the step of controlling the delay operation of the defrosting heater in step S20 includes:
step S21, acquiring the working time of the defrosting heater, the preset working time T1 corresponding to the working voltage and the preset working time T2 corresponding to the rated voltage;
step S22, judging whether the sum of the working time length and the preset working time length T2 is greater than the preset working time length T1;
step S23, controlling the defrosting heater to be continuously electrified for a preset working time length T2 under the condition that the sum of the working time length and the preset working time length T2 is less than or equal to the preset working time length T1;
and step S24, controlling the ratio of the preset working time length T1 to the working time length of the defrosting heater to be electrified continuously under the condition that the sum of the working time length T2 and the preset working time length T3526 is greater than the preset working time length T1.
When the defrosting heater starts to work, a processing unit arranged in the refrigerator immediately counts time, and the working time of the defrosting heater is calculated; in addition, the processing unit built in the refrigerator can derive the preset operating time T2 of the refrigerator according to the preset rated power of the refrigerator. After the refrigerator is determined to be in a low-voltage environment, the working time of the defrosting heater, the preset working time T1 corresponding to the working voltage and the preset working time T2 corresponding to the rated voltage are obtained, and the delayed working of the defrosting heater is controlled according to the working time, the preset working time T1 and the preset working time T2.
For example, the preset working time period T1 of the refrigerator is 100 minutes, the preset working time period T2 is 30 minutes, when the working time period of the refrigerator is 30 minutes, the sum of the preset working time period T2 and the working time period is 60 minutes, and compared with the preset working time period T1, obviously, the 60 minutes is less than 100 minutes, and the sum of the working time period T2 and the preset working time period T1 is less than or equal to the preset working time period T1, the defrosting heater is controlled to continue to be electrified and operated for 30 minutes.
When the working time of the refrigerator is 80 minutes, the sum of the preset working time T2 and the working time is 110 minutes, and the numerical value of the sum of the preset working time T1 is compared with the preset working time T1, obviously, the sum of the working time T2 and the preset working time T1 is greater than the preset working time T1, the defrosting heater is controlled to be continuously electrified for a certain time, it is easy to understand that the specific value of the continuous electrified time is the ratio of the preset working time T1 to the working time, and when the accumulated working time of the defrosting heater reaches the low-pressure working time, the defrosting heater is controlled to stop working.
In the above manner, in the low-pressure environment, the defrosting heater is flexibly controlled to operate for a certain time in a delayed manner according to the operating time of the defrosting heater, the preset operating time T1 and the preset operating time T2, so as to achieve the expected defrosting effect.
Further, the step of acquiring the preset operating time period T1 corresponding to the operating voltage in the step S21 includes:
step S211, obtaining a voltage ratio according to the working voltage and the rated voltage of the refrigeration equipment;
step S212, determining a preset voltage ratio range in which the voltage ratio is located from the plurality of preset voltage ratio ranges, and obtaining a preset operating time T1 corresponding to the preset voltage ratio range in which the voltage ratio is located.
In this embodiment, a plurality of voltage ratio ranges are preset, and it is easy to understand that each voltage ratio range corresponds to a different preset operating time period T1. After the working voltage and the rated voltage of the refrigerator are obtained, the working voltage and the rated voltage are divided to obtain a voltage ratio, a preset voltage ratio range where the voltage ratio is located is determined from a plurality of preset voltage ratio ranges, and a preset working duration T1 corresponding to the voltage ratio range is obtained according to a preset corresponding relation, so that a preset working duration T1 is obtained. It is easily understood that, in a low-pressure environment, the defrosting heater cannot achieve the expected defrosting effect, and therefore the preset operating time period T1 is set to be greater than the preset operating time period T2, as a preferable scheme, the preset operating time period T1 is set to be greater than or equal to 100 minutes, and the preset operating time period T2 is set to be greater than or equal to 30 minutes, and of course, specific values of the preset operating time period T1 and the preset operating time period T2 may be set correspondingly according to the performance of the refrigerator, such as the operating power of the refrigerator and other factors. Through the mode, the corresponding preset working time T1 is obtained according to the actual working voltage of the refrigeration equipment, and the specific time of the delayed working of the defrosting heater is controlled, so that the defrosting control of the refrigeration equipment is more suitable for the actual running condition of the refrigeration equipment.
Further, in step S20, the operation voltage of the refrigeration apparatus is less than the rated voltage, and the step of controlling the defrosting heater to operate with a delay time includes:
and step S25, controlling the defrosting heater to work in a delayed mode, wherein the working voltage of the refrigeration equipment is smaller than the rated voltage, and the ratio of the working voltage to the rated voltage is within a preset range.
Further, when the refrigeration apparatus reaches the defrosting exit condition in step S10, after the operating voltage of the refrigeration apparatus is obtained, the method further includes:
and step S30, controlling the defrosting heater to stop working when the working voltage of the refrigeration equipment is less than the rated voltage and the ratio of the working voltage to the rated voltage is not within a preset range.
Further, when the refrigeration apparatus reaches the defrosting exit condition in step S10, after the operating voltage of the refrigeration apparatus is obtained, the method further includes:
and step S40, controlling the defrosting heater to stop working when the working voltage of the refrigeration equipment is greater than or equal to the rated voltage.
In this embodiment, a rated voltage of the refrigerator, that is, a full-load input voltage of the refrigerator in a normal operating state is preset, and a certain voltage range is also preset. And when the ratio of the working voltage to the rated voltage is within a preset range, determining that the refrigerator is in a low-voltage condition. After the working voltage of the refrigerator is obtained, the working voltage of the refrigerator is compared with a preset rated voltage, specifically, the magnitude relation between the working voltage and the rated voltage can be judged firstly, the specific value of the working voltage is divided by the specific value of the rated voltage on the premise that the working voltage is smaller than the rated voltage, the ratio of the working voltage to the rated voltage is obtained, and whether the ratio is within a preset range or not is judged. In addition, the defrosting heater can be controlled to operate in a delayed mode by comparing the difference between the operating voltage and the rated voltage.
Preferably, if the ratio of the working voltage of the refrigerator to the rated voltage is less than or equal to 90%, determining that the current working voltage of the refrigerator is low voltage under the condition of low voltage of the refrigerator; and if the ratio of the working voltage of the refrigerator to the rated voltage is greater than 90%, determining that the current working voltage of the refrigerator is not low voltage. When the working voltage of the refrigerator is not low voltage or is more than or equal to the rated voltage, the fact that enough voltage input is obtained in the working process of the refrigerator is shown, the working efficiency of the defrosting heater is consistent with the expected working efficiency, the expected defrosting effect can be achieved, and the defrosting heater is directly controlled to be powered off, so that the defrosting heater stops working.
For example, the preset rated voltage is 220V, when the obtained working voltage of the refrigerator is 200V, the specific value 200 of the working voltage is divided by the specific value 220 of the rated voltage to obtain that the ratio of the working voltage to the rated voltage is 90.9%, and then the refrigerator is determined not to be in a low-voltage state at the moment; when the obtained working voltage of the refrigerator is 110V, the specific value 110 of the working voltage is divided by the specific value 220 of the rated voltage to obtain that the ratio of the working voltage to the rated voltage is 50%, and it is determined that the refrigerator is in a low-voltage state at the time.
In this embodiment, whether the working voltage of the refrigerator is the low voltage is determined through the above manner, it should be understood that whether the working voltage of the refrigerator is the low voltage may also be determined through other manners, and this embodiment does not limit other technical means that may achieve the same effect; for example, a voltage value may be preset, after the current operating voltage of the refrigerator is obtained, the current operating voltage is compared with the preset voltage value, and if the operating voltage is lower than the preset voltage value, it is determined that the refrigerator is in a low-voltage environment.
In this embodiment, the current working state of the refrigeration equipment is determined according to the magnitude relationship between the working voltage and the rated voltage, and the defrosting heater is intelligently controlled to delay or stop working according to the current working state, so that the expected defrosting effect is achieved.
Further, referring to fig. 4, fig. 4 is a schematic flow chart of a defrosting control method for a refrigeration apparatus according to another embodiment of the present invention, where in the case that the refrigeration apparatus reaches the defrosting exit condition in step S10, before the obtaining of the operating voltage of the refrigeration apparatus, the method further includes:
step S50, detecting whether the working duration of the defrosting heater is greater than or equal to the preset defrosting exit duration and whether the temperature of the refrigerating chamber of the refrigerating equipment is greater than or equal to the preset temperature;
step S60, determining that the refrigeration equipment reaches a defrosting exit condition under the condition that the working duration of the defrosting heater is greater than or equal to a preset defrosting exit duration or the temperature of the refrigeration compartment of the refrigeration equipment is greater than or equal to a preset temperature;
and step S70, determining that the refrigeration equipment does not reach the defrosting exit condition under the condition that the working duration of the defrosting heater is less than the preset defrosting exit duration and the temperature of the refrigeration compartment of the refrigeration equipment is less than the preset temperature.
Further, after the step S70 determines that the refrigeration apparatus does not reach the defrosting exit condition, the method further includes:
and step S80, controlling the defrosting heater to continue working under the condition that the refrigeration equipment does not reach the defrosting exit condition.
In the defrosting process of the refrigerator, the working duration of the defrosting heater and the temperature of a refrigerating chamber of the refrigerator are acquired in real time. Optionally, the processing unit in the refrigerator has a corresponding timing function, and immediately records the energization time of the defrosting heater after the defrosting heater is energized to work, and the energization time is used as the working duration of the defrosting heater; in addition, the temperature of the refrigerating chamber of the refrigerator can be acquired in real time through a temperature sensing unit in the refrigerator. In this embodiment, in order to determine whether the refrigerator reaches the corresponding defrosting exit condition, a preset defrosting exit duration and a preset defrosting exit temperature are preset. As a preferred method, the preset defrosting exit time is preferably 40 minutes, and the preset temperature is preferably 4 degrees, it should be understood that the above-mentioned limitations on the preset defrosting exit time and the preset temperature are only needed for elaborating the embodiment, and the actual values of the preset defrosting exit time and the preset temperature may be other values within a reasonable range.
Recording the electrifying time of the defrosting heater through the processing unit, and judging whether the working duration of the defrosting heater is greater than or equal to a preset defrosting exit time or not after the working duration of the defrosting heater is obtained; the temperature of the refrigeration chamber of the refrigerator is monitored in real time through the temperature sensing unit, and whether the monitored instantaneous temperature of the refrigeration chamber of the refrigerator is larger than or equal to the preset temperature or not is judged.
Under the condition that the working duration of the defrosting heater is greater than or equal to the preset defrosting exit duration, determining that the refrigerator reaches a defrosting exit condition; and under the condition that the monitored temperature of the refrigerating chamber of the refrigerator is greater than or equal to the preset temperature, determining that the refrigerator reaches a defrosting exit condition. That is, even if the operation duration of the defrosting heater is less than the preset defrosting exit duration, it is still determined that the refrigerator reaches the defrosting exit condition in the case where the temperature of the refrigerating compartment of the refrigerator is equal to or greater than the preset temperature. As another case, it can be determined that the refrigerator does not reach the defrosting exit condition only when the operation duration of the defrosting heater is less than the preset defrosting exit duration and the temperature of the refrigerating compartment of the refrigerator is less than the preset temperature.
Particularly, under the condition that the working duration of the defrosting heater is less than the preset defrosting exit duration and the temperature of the refrigerating chamber of the refrigerator is less than the preset temperature, the refrigerator is determined not to reach the defrosting exit condition, at the moment, the defrosting effect of the refrigerator does not reach the expected defrosting effect, and the defrosting heater is controlled to continue to work until the refrigerator reaches the defrosting exit condition.
In the above mode, the certain defrosting quitting condition is preset in the embodiment, excessive defrosting of the refrigeration equipment in the defrosting process is avoided, and when the refrigeration equipment does not reach the defrosting quitting condition, the defrosting heater is controlled to continuously work, so that the expected defrosting effect is realized, and meanwhile, the energy consumption of the operation of the refrigeration equipment is saved.
