Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A control method of an ice maker, a control device of an ice maker, an electronic device, and a computer-readable storage medium according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of an ice maker according to an embodiment of the present invention. As shown in fig. 1, the method for controlling an ice maker according to an embodiment of the present invention may include the steps of:
and S1, receiving an ice making instruction.
In practical applications, a user can send an ice making instruction to the ice maker through a function key (e.g., a touch screen key or an entity key) according to actual needs. Therefore, the ice maker can judge whether ice making is needed according to whether the ice making instruction is received.
And S2, controlling water inflow according to the ice making instruction, and acquiring a first temperature before water inflow.
It should be noted that, when the ice maker starts to work, before the ice maker starts to feed water, the temperature of the ice maker body and the temperature near the ice maker body are generally reduced to a preset temperature, for example, 1 ℃ or-3 ℃, and then the ice maker is controlled to start to feed water, so that when the ice maker feeds water, the water temperature is rapidly reduced, and the frost formation amount can be effectively reduced.
That is, after receiving the ice making instruction, the ice maker can be controlled to operate in an ice making and cooling state to reduce the temperature of the ice maker body and the temperature near the ice maker body, and whether the temperature meets the water inlet condition is judged, that is, whether the temperature of the ice maker body and the temperature near the ice maker body reach the preset temperature is judged, if the water inlet condition is met, the temperature of the ice maker body is obtained through the ice removing sensor, that is, the first temperature T1 of the ice maker before water inlet is obtained, and the ice maker is controlled to start water inlet.
The ice-removing sensor can be tightly attached to the ice machine body so as to feed back the temperature of the ice machine body.
And S3, acquiring a second temperature after water feeding.
After the ice maker enters water, the temperature of the ice maker body can be obtained again through the ice-shedding sensor, namely, the second temperature T2 of the ice maker after water enters is obtained.
And S4, judging whether water is normally fed according to the first temperature and the second temperature.
According to an embodiment of the present invention, judging whether water is normally supplied according to a first temperature and a second temperature includes: acquiring the temperature difference between the second temperature and the first temperature; judging whether the temperature difference is greater than a preset threshold value or not; if the water inlet amount is larger than or equal to the preset threshold value, judging that water enters normally; and if the water inlet amount is smaller than the preset threshold value, judging that water is not normally fed.
Specifically, since the temperature of the body and the vicinity of the ice maker is reduced to a lower temperature before water enters the ice maker, the temperature of the ice maker body is significantly increased by the temperature of the entering water after water enters the ice maker if the ice maker normally enters water. Therefore, in practical application, a first temperature T1 before water enters the ice maker and a second temperature T2 after water enters the ice maker can be obtained, and whether the ice maker normally enters water can be judged according to the first temperature T1 and the second temperature T2.
If the temperature difference between the second temperature T2 and the first temperature T2 is greater than or equal to a preset threshold, it indicates that the body temperature of the ice maker is significantly increased after water enters the ice maker, and therefore, the ice maker can be judged to normally enter water; if the temperature difference between the second temperature T2 and the first temperature T1 is smaller than the preset threshold, it indicates that the temperature change of the ice machine body is not obvious, and after the ice machine makes ice, water inflow is abnormal, for example, water inflow of the ice machine is not normal due to the fact that a water inlet pipe is not installed or water inflow failure occurs, and at this time, it can be determined that the ice machine does not normally inflow water.
Therefore, whether the ice maker normally enters water can be accurately judged according to the first temperature T1 before the ice maker enters water and the second temperature T2 after the ice maker enters water.
And S5, if the water is judged not to be normally fed, the deicing heating is stopped.
According to an embodiment of the present invention, further comprising: and if normal water inflow is judged, refrigerating and ice making as well as deicing and heating are carried out.
Specifically, after receiving an ice making instruction, when the refrigerator is judged to meet the water inlet condition, a first temperature T1 before water enters the ice maker can be obtained through the ice removing sensor, the ice maker is controlled to start water inlet, a second temperature T2 before water enters the ice maker is obtained through the ice removing sensor, whether the ice maker normally enters water is judged according to the first temperature T1 and the second temperature T2, if the ice maker normally enters water, the ice maker is controlled to normally perform operations such as ice making and ice removing heating, and if the ice maker is judged not to normally enter water, the ice maker is controlled to stop performing ice removing heating. Therefore, whether the ice machine normally intakes water can be accurately judged, and when the water intake is judged to be abnormal, the ice-removing heating is stopped in time, so that the temperature rise of ice storage and ice making regions can be avoided, the energy waste can be avoided, and the adverse conditions of extra condensation, cold leakage and the like can be avoided.
According to an embodiment of the present invention, if it is judged that water is not normally supplied, the deicing heating is stopped, including: if the water is not normally fed, adding 1 to the detection value, and controlling to perform primary deicing heating; after the preset time, acquiring a third temperature after water inflow; judging whether water is normally fed according to the first temperature and the third temperature; judging whether water is normally fed according to the first temperature and the third temperature; and if the normal water inflow is judged, clearing the detection value, and performing refrigeration, ice making and deicing heating.
Specifically, in order to improve the accuracy of the determination, in practical applications, the number of times of water inflow abnormality of the ice maker is recorded by a counter to obtain a detection value, and the refrigerant is controlled according to the size of the detection value.
And if the ice maker is judged not to normally feed water according to the second temperature T2 and the first temperature T1, adding 1 to the detection value, and controlling the ice maker to perform primary deicing heating, namely allowing the ice maker to perform idle heating and deicing once when the ice maker is abnormally fed water for the first time. After the preset time, the third temperature T3 after the water enters the ice maker can be obtained again through the deicing sensor, and whether the water enters the ice maker normally is judged according to the first temperature T1 and the third temperature T3. If the temperature difference between the third temperature T3 and the first temperature T1 is smaller than a preset threshold value, the ice maker is judged not to normally enter water, at the moment, 1 can be added to the detection value, the ice maker is controlled to stop deicing and heating, the detection value is cleared, and the ice maker is controlled to be in an ice storage state; if the temperature difference between the third temperature T3 and the first temperature T1 is greater than or equal to a preset threshold value, the ice maker is judged to normally feed water, at the moment, the detection value can be cleared, and the ice maker is controlled to continue to perform refrigeration and ice making and ice removal heating.
That is to say, when the water inflow of the ice maker is detected for a plurality of times, the water inflow abnormality of the ice maker is judged, and the ice maker is controlled to stop ice-removing heating, so that the detection accuracy can be greatly improved, and the reliability of the system is improved.
In summary, according to the control method of the ice maker in the embodiment of the invention, the ice making instruction is received, the water is controlled according to the ice making instruction, the first temperature before the water is fed is obtained, the second temperature after the water is fed is obtained, whether the water is fed normally is judged according to the first temperature and the second temperature, and the ice removing heating is stopped when the water is not fed normally. Therefore, whether the ice machine normally intakes water can be accurately judged, and when the water intake is judged to be abnormal, the ice-removing heating is stopped in time, so that the temperature rise of ice storage and ice making regions can be avoided, the energy waste can be avoided, and the adverse conditions of extra condensation, cold leakage and the like can be avoided.
