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 a dispenser in a refrigeration appliance, a control device of a dispenser in a refrigeration appliance, and a refrigeration appliance having the same according to embodiments of the present invention will be described below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a control method of a dispenser in a refrigeration appliance according to an embodiment of the present invention.

In one embodiment of the invention, the refrigeration equipment can be a refrigerator, an ice maker or a refrigerator with an ice maker, wherein the ice maker is arranged on a door body of the refrigerator, and an ice outlet of the ice maker is communicated with a dispenser on the door body.

As shown in fig. 1, a control method of a dispenser in a refrigeration appliance according to an embodiment of the present invention may include the steps of:

and S1, acquiring the time of discharging the whole ice and the time of discharging the crushed ice of the dispenser when the current ice discharging of the dispenser is finished.

And S2, calculating the heating opening time according to the time of discharging the whole ice and the time of discharging the crushed ice.

According to one embodiment of the present invention, the heating-on time is calculated according to the following formula (1):

Ta＝K1×T1+K2×T2(1)

ta is heating starting time, T1 is time of discharging whole ice of the dispenser, T2 is time of discharging crushed ice of the dispenser, K1 and K2 respectively show starting time coefficients of a dispenser heater corresponding to the whole ice and a dispenser heater corresponding to the crushed ice, and the residual ice slag at the ice outlet after the crushed ice is discharged is more than the residual ice slag at the ice outlet after the whole ice is discharged, so that K1 is less than K2.

It should be noted that, the values of K1 and K2 corresponding to different ambient temperatures and different ambient humidities are different, and the values of the two coefficients at different ambient temperatures and humidities are obtained through a large number of experimental tests and are stored in the refrigeration equipment in advance so as to be called at any time.

That is, the heating-on time of the heater can be calculated according to the time of discharging the whole ice from the dispenser, the heater-on time coefficient when discharging the whole ice, the time of discharging the crushed ice, and the heater-on time coefficient when discharging the crushed ice.

And S3, controlling the heater to be continuously started according to the heating starting time to heat the distributor.

According to one embodiment of the present invention, controlling a heater to be continuously turned on according to a heating turn-on time to heat a dispenser includes: and when the time for which the heater is continuously started is less than the heating starting time, controlling the heater to be continuously started.

Further, according to an embodiment of the present invention, the method for controlling a dispenser in a refrigeration apparatus further includes: and when the time for continuously opening the heater reaches the heating opening time, controlling the heater to be opened or closed by taking the preset opening time and the preset closing time as a period. The preset on-time and the preset off-time may be calibrated according to actual conditions, for example, determined according to the current outdoor environment temperature and the current environment humidity, where the current environment temperature is higher, and the longer the preset on-time of the heater is, the shorter the preset off-time is.

Specifically, when the user does not take ice, the heater performs heating control on the dispenser according to a normal cycle, for example, the working cycle of the heater is 1 minute, and if the current outdoor environment temperature is far higher than the temperature of the ice outlet of the dispenser, the heating wire works for 45s and stops for 15s in order to avoid condensation. Because the user can appear ice slag and remain the condition at the ice outlet in the in-process of getting ice, especially the user is when getting garrulous ice, more easily remains ice slag at the ice outlet. In order to prevent the heater from being in the stage of stopping working when ice slag remains at the ice outlet of the dispenser, the ice slag is difficult to melt, so that the ice outlet is frozen, the normal use of a user is influenced, and the heater is controlled to be continuously started to heat the dispenser according to the time when the dispenser takes whole ice and crushed ice.

Specifically, the user selects whether the ice needs to be made or crushed or both according to the needs of the user, for example, the user needs to make the ice and crushed. When a user uses the cup to take ice, the user firstly selects the whole ice through a function key on the interface, the cup contacts a sensor on the refrigeration equipment to judge that the user needs to take the ice, the dispenser is controlled to discharge the whole ice, timing is started, and when the cup leaves, the timing is stopped, and the time T1 of discharging the whole ice of the dispenser is recorded. The user selects the crushed ice through a function key on the interface, the cup contacts a sensor on the refrigeration equipment to judge that the user needs to take the ice, the dispenser is controlled to discharge the crushed ice, timing is started, when the cup leaves, the timing is stopped, the time T2 when the dispenser discharges the crushed ice is recorded, and the user finishes one-time ice taking action.

After the ice is discharged, timing is started (timing is started after the user finishes the actions of taking the whole ice and crushing the ice), and the heater is controlled to start heating the distributor. During the process of controlling the heater to heat the dispenser, the continuous heater on time T (namely the continuous time of forcibly turning on the heater after the dispenser is discharged with ice) is judged to be compared with the heating starting time, so as to select the corresponding control strategy. When the heater duration time T is less than K1 XT 1+ K2 XT 2, the risk that the ice outlet of the dispenser is frozen is shown to a certain extent, at this time, the heater is forced to be continuously turned on (namely, the heater does not work according to the normal period of the heater) to heat the dispenser until the heater is continuously turned on for more than or equal to the heating on time, and the dispenser is heated according to the normal heating period of the heater, for example, the heating period of the heater is one minute, 20 seconds are turned on, and 40 seconds are turned off, so that the phenomenon that the ice outlet is frozen due to incomplete melting and evaporation of the residual ice slag at the ice outlet after the user takes ice can be effectively avoided.

According to an embodiment of the present invention, in controlling the heater to be continuously turned on, the method further includes: acquiring a heating starting limit value; and when the time for which the heater is continuously opened is greater than the heating opening limit value, the heater is controlled to be opened or closed by taking the preset opening time and the preset closing time as a period. Wherein, the heating opening limit value can be calibrated according to the actual situation.

That is, in order to avoid that the ice in the dispenser melts due to the fact that the heater is continuously turned on for too long time, and the service life of the heater is reduced due to the fact that the heater is continuously turned on for a long time, the magnitude relation between the continuous turning-on time of the heater and the heating turning-on limit value is also judged in real time in the continuous turning-on process of the lightweight heater, wherein when the continuous turning-on time of the heater is larger than the heating turning-on limit value, the forced continuous turning-on of the heater is stopped, and the normal turning-on or turning-; and when the continuous opening time of the heater is less than or equal to the heating opening limit value, controlling the heater to be continuously opened according to the relation between the continuous opening time of the heater and the heating opening time so as to heat the distributor.

As a specific example, as shown in fig. 2, the control method of the dispenser in the refrigeration appliance may include the steps of:

and S101, starting the ice maker to work.

S102, acquiring the current ambient temperature and ambient humidity.

And S103, determining the heating period of the heater according to the current ambient temperature and humidity.

And S104, heating the distributor and stopping heating by the heater according to the determined heating period.

And S105, judging whether the dispenser has ice discharging action and finishes ice discharging. If yes, go to step S106; if not, return to step S103.

And S106, recording the time T1 for discharging the whole ice and the time T2 for discharging the crushed ice of the dispenser, and starting timing after the ice is discharged from the dispenser. It should be noted that the time T counted after the ice is discharged from the dispenser is the time for the heater to be continuously turned on after the ice is discharged.

S107, it is judged whether T < K1 × T1+ K2 × T2 is satisfied. If yes, go to step S108; if not, return to step S103.

It should be noted that K1 and K2 are coefficients.

And S108, continuously turning on the heater to heat the distributor.

And S109, judging that the heater continuous opening time T is less than the heating opening limiting value T3. If yes, returning to the step S108; if not, return to step S103.

Therefore, after the ice is taken by the user, the heater is forced to be continuously started to heat the distributor, and the continuous heating time of the heater is judged according to the ice taking time and the proportional coefficient of the starting time of the heater corresponding to different ice types, so that the phenomenon that the ice outlet is frozen due to incomplete melting and evaporation of ice residues left at the ice outlet after the ice is taken by the user to influence the normal ice taking of the user can be effectively avoided.

In summary, according to the control method of the dispenser in the refrigeration apparatus of the embodiment of the invention, when the current ice discharging of the dispenser is completed, the time for the dispenser to discharge the whole ice and the time for the dispenser to discharge the crushed ice are obtained, the heating on time is calculated according to the time for the dispenser to discharge the whole ice and the time for the dispenser to discharge the crushed ice, and the heater is controlled to be continuously turned on according to the heating on time to heat the dispenser. Therefore, the method can effectively prevent the ice outlet from being frozen after the ice outlet action of the distributor, and improve the user experience.
