Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, refrigerator of the present invention comprise compressor (not shown), evaporimeter 1, in order to remove the frost on described evaporimeter 1 heater strip 2 and in order to control the control panel (not shown) that described heater strip 2 is opened or closed.
Described heater strip 2 is located at the below of described evaporimeter 1.
Described evaporimeter 1 is provided with Temperature Humidity Sensor 3, to detect the temperature and humidity around evaporimeter 1.Described Temperature Humidity Sensor 3 is arranged on evaporimeter 1, and in the present embodiment, described Temperature Humidity Sensor 3 is arranged on the top of described evaporimeter 1; Certainly, in other embodiments, the particular location of described Temperature Humidity Sensor 3 can be selected according to actual needs, as long as described Temperature Humidity Sensor 3 and described heater strip 2 keep at a certain distance away.Temperature Humidity Sensor 3 and heater strip 2 keep at a certain distance away and arrange is in order to avoid because heater strip 2 surface temperature is too high, situation that is that cause Temperature Humidity Sensor 3 to damage occurs in abnormal cases.Described Temperature Humidity Sensor 3 sends the temperature signal received and moisture signal to described control panel, is controlled unlatching or the closedown of described heater strip 2 and described compressor by described control panel.
As shown in Figure 2, refrigerator of the present invention, when defrosting, mainly comprises following step:
There is provided a Temperature Humidity Sensor 3, described Temperature Humidity Sensor 3 detects respectively to the temperature and humidity around described evaporimeter 1;
Described Temperature Humidity Sensor 3 sends the temperature signal detected and moisture signal to described control panel;
The temperature signal received and moisture signal and preset value compare, to control unlatching or the closedown of described heater strip 2 and described compressor by described control panel; Described preset value comprises the first preset value and the second preset value, and the first preset value and the second preset value can be arranged from main separation according to the difference of the structure of refrigerator, model;
If the temperature signal that control panel receives and moisture signal are lower than equaling the first preset value, then control panel controls that described heater strip 2 is opened, described compressor cuts out, and enters defrost pattern; If the temperature signal that control panel receives and moisture signal are higher than the second preset value, then control panel controls that described heater strip 2 is closed, described compressor opens, and enters refrigeration mode.
Described first preset value comprises the first temperature preset value and the first humidity preset value, and described second preset value comprises the second temperature preset value and the second humidity preset value.Described first temperature values is-10 DEG C ~-30 DEG C, and described first humidity values is 25%RH ~ 45%RH, and described second temperature values is 0 DEG C ~ 15 DEG C, and described second humidity values is 60%RH ~ 80%RH.Certainly, described first temperature preset value, the first humidity preset value, the second temperature preset value and the second humidity preset value can any one numerical value in range of choice as required, as long as enter defrost pattern when can ensure that the frost of refrigerator on described evaporimeter 1 has influence on refrigeration for refrigerator efficiency, when the frost on described evaporimeter 1 reduces to a certain degree, enter refrigeration mode.
In the present embodiment, the temperature signal received and moisture signal compare with the first temperature preset value and the first humidity preset value by described control panel simultaneously respectively, and only at temperature signal lower than equaling the first temperature preset value, moisture signal is lower than when equaling the first humidity preset value simultaneously, control panel just can control that described heater strip 2 is opened, compressor cuts out, and refrigerator enters defrost pattern.That is: if one of them only having temperature signal and moisture signal is lower than equaling corresponding preset value, so control panel can not control heater strip 2 and open, and now heater strip 2 keeps closed condition, compressor keeps opening.In like manner, if the temperature signal that control panel receives is higher than the second temperature preset value, when simultaneously moisture signal is higher than the second humidity preset value, control panel just can control that described heater strip 2 is closed, compressor is opened, and refrigerator enters refrigeration mode.
Refrigerator of the present invention and defrosting control method thereof, by arranging Temperature Humidity Sensor 3 on evaporimeter 1, to detect the temperature and humidity around evaporimeter 1, thus, the comparative result of the temperature signal that control panel can detect according to Temperature Humidity Sensor 3 and moisture signal and preset value controls unlatching or the closedown of described heater strip 2 and described compressor, defrost is carried out when such design makes the frost of refrigerator only on evaporimeter 1 run up to a certain degree, and freeze when frost reduces to a certain degree, not only reduce energy waste, and structure is simple, method is simple and easy, cost is lower.
Above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not depart from the spirit and scope of technical solution of the present invention.
