detailed description

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

The following describes the control method and system of the refrigerator according to the embodiments of the present invention and the refrigerator having the same with reference to the accompanying drawings. First, the control method of the refrigerator according to the embodiments of the present invention will be described with reference to the accompanying drawings.

Fig. 1 is a flowchart of a control method for a refrigerator according to an embodiment of the present invention. In an embodiment of the present invention, the refrigerator may have a refrigerator compartment, a freezer compartment, a heating device and a refrigeration device. Wherein, the heating device is used for heating the refrigerating room, and the refrigerating device is used for cooling the refrigerating room and the freezing room.

As shown in Figure 1, the control method of the refrigerator includes the following steps:

In step S101, the temperature of the freezing compartment is detected.

There are many ways to detect the temperature. For example, one or more temperature sensors are respectively installed in the refrigerator compartment and the freezer compartment, which are not specifically limited here.

In step S102, if the temperature of the freezing compartment is higher than the freezing start-up temperature, the refrigeration device is controlled to cool the refrigeration compartment and the freezing compartment at the same time, and the temperature of the refrigeration compartment is further detected.

That is to say, the refrigerator and freezer are refrigerated by the refrigerating device, and the temperature of the refrigerator and freezer is lowered to meet the refrigeration demand, especially the temperature of the freezer needs to be kept within the freezing temperature range such as -4 to -24 degrees.

In step S103, if the temperature of the refrigerating chamber is lower than the refrigerating shutdown temperature, the heating device is controlled to heat the refrigerating chamber.

When lowering the temperature of the freezer, in order to keep the temperature of the freezer within the freezing temperature range, the temperature of the freezer will inevitably decrease continuously, so that the temperature of the freezer cannot be kept within the range of refrigerating temperatures, such as 5 to 15 degrees. In the control method of the embodiment of the present invention, the heating device is used to heat the refrigerating chamber, so that the temperature of the refrigerating chamber is kept within the refrigerating temperature range.

Optionally, in an embodiment of the present invention, the cooling device may be a compressor, and the heating device may be a heating wire. That is to say, the refrigerator and the freezer can share the same set of refrigeration system, that is, the same refrigeration device, so that the two compartments of the refrigerator can have the function of refrigeration and freezing at the same time without changing the system of the refrigerator and increasing the cost. , the function is no longer a single freezing function, or switching between the freezing function and the refrigeration function, so as to better meet the needs of users.

For example, a refrigerator may have multiple compartments, which are respectively used for refrigeration and freezing. For the convenience of those skilled in the art to understand, two compartments are used as an example below. Wherein, as shown in Figure 2, the freezer has two compartments, compartment A is a freezing compartment, compartment B is a refrigerating compartment, and each compartment is respectively provided with a temperature sensor, in short, compartment A is provided with a freezing sensor , Compartment B is provided with a refrigeration sensor, so that the freezing chamber can control the opening and closing of the refrigeration device through the temperature detected by the freezing sensor, and the refrigeration chamber can control the opening and closing of the heating device through the temperature detected by the refrigeration sensor and the opening time of the heating device Closed, so that the two compartments of the refrigerator have the functions of refrigerating and freezing respectively, even if the refrigerator is using the freezing function, it can also meet the user's refrigerating function, which is convenient for the user and improves the user's experience.

Further, in one embodiment of the present invention, after controlling the heating device to heat the refrigerating chamber, it also includes: when the heating device is turned on, obtaining the indoor temperature of the freezing chamber and the indoor temperature of the refrigerating chamber; and the indoor temperature of the refrigerating chamber and the current indoor temperature of the freezing chamber and the current indoor temperature of the refrigerating chamber to obtain a cooling ratio; and control the opening or closing of the refrigeration device and the heating device according to the cooling ratio.

Wherein, in one embodiment of the present invention, controlling the opening or closing of the cooling device and the heating device according to the cooling ratio further includes: if the cooling ratio is greater than the first preset threshold, turning off the heating device and turning on the cooling device; The ratio is less than the first preset threshold and greater than the second preset threshold, then turn off the heating device, and turn off the cooling device, wherein the first preset threshold is greater than the second preset threshold; and if the cooling ratio is less than the second preset threshold, Then turn on the heating device and turn off the cooling device.

Optionally, in an embodiment of the present invention, the first preset threshold may be 4.33, and the second preset threshold may be 1.81. It should be noted that this value is for example purposes only, and the actual preset threshold is not limited thereto, and can be set according to actual application conditions. Because this value is the working critical point of the heating wire, the heating wire does not need to be turned on frequently, which improves the reliability of the heating wire, prolongs the service life of the heating wire, better ensures the safety and reliability of the refrigerator, and saves energy. cut costs.

The control method of the refrigerator according to the embodiment of the present invention will be introduced in detail below.

In the embodiment of the present invention, the refrigerator may have two compartments, and each compartment has a temperature sensor, so that the control can be realized through the electric control board. Specifically, the temperature of the freezing chamber and the refrigerating chamber can be set through the electric control board. It should be noted that each set temperature of the freezer corresponds to the start-up temperature point (equivalent to the start-up temperature of the freezer) and the stop temperature point of a refrigeration device (the compressor is taken as an example below); each set temperature of the freezer , corresponding to the opening temperature point (refrigeration shutdown temperature) of a heating device (the heating wire is used as an example below); in addition, the closing control of the heating device needs to calculate the ratio of the temperature rise rate of the refrigerator compartment to the temperature rise rate of the freezer compartment within a period of time (equivalent to the cooling ratio) to control, and in different ratio ranges, the control action of the heating device is different. This parameter has been verified by a large number of performance experiments, and it is obtained after correction. The following examples will be given to make it easier for those skilled in the art. understand.

Fig. 3 is a flowchart of a method for controlling a compressor and a heating wire according to an embodiment of the present invention. As shown in Figure 3, the control method includes the following steps:

In step S301, press the key to adjust the temperature of the refrigerator compartment and the temperature of the freezer compartment.

For example, users can set the temperature of the freezer and refrigerator through the electric control panel.

In step S302, it is judged whether the temperature of the freezing chamber is higher than the start-up point, that is, the start-up temperature point. If yes, execute step S303; if no, continue to wait.

That is to say, first judge whether the temperature of the freezer exceeds the start-up temperature point. If it exceeds, it means that the freezing effect required by the user cannot be achieved, and the freezer should be refrigerated immediately to reduce the temperature of the freezer.

In step S303, the compressor is turned on to request cooling.

That is to say, when the temperature of the freezing compartment exceeds the start-up temperature point, it means that the temperature of the freezing compartment is too high, and at this time, the compressor is turned on for cooling.

In step S304, the temperature inside the chamber decreases.

It should be noted that during the cooling process, the temperature in the middle chamber of the refrigerator (including the refrigerator and freezer) will continue to decrease.

In step S305, it is judged whether the temperature of the freezing chamber is lower than the shutdown point, that is, the shutdown temperature point. If the temperature of the freezer is lower than the stop point, execute step S306; if not, continue to execute step S305.

In step S306, the compressor is stopped.

That is to say, after the temperature of the freezer is lower than the stop point, it means that the refrigeration can be stopped and the compressor can be turned off.

In step S307, it is judged whether the temperature of the refrigerating chamber is lower than the starting point, that is, the starting temperature point of the heating wire. If yes, execute step S308; if no, continue to wait.

It should be noted that, while step S303 is executed, or after step S301 is executed, step S307 is executed.

In step S308, the heating wire is turned on to request heating.

In step S309, the temperature inside the refrigerator rises.

During the heating process, the temperature of the refrigerated compartment will continue to rise due to heating.

In step S310, further control is performed according to the value of A1/A2 (ie, the cooling ratio).

That is to say, in different ratio intervals, the control action of the heating wire is different.

The control action of the heating wire in different ratio intervals will be described in detail below.

Fig. 4 is a flowchart of a method for controlling a heating wire according to a specific embodiment of the present invention. As shown in Figure 4, the control method further includes the following steps:

In step S401, wait for the heating wire to be turned on. That is to say, it is first judged whether the temperature of the refrigerator compartment is lower than the opening temperature of the heating wire.

Furthermore, if the heating wire is turned on, execute step S402; if the heating wire is not turned on, continue to execute step S401.

In step S402, record the reference time point t1,

And, while step S402 is being executed, step S403 is executed.

In step S403, the temperature q1 sensed by the refrigeration sensor and the temperature p1 sensed by the freezing sensor at this time are recorded.

That is, the indoor temperature q1 of the refrigerating chamber and the indoor temperature p1 of the freezing chamber detected by the refrigerating sensor at the reference time point t1 are recorded.

In step S404, the temperature in the refrigerator increases significantly, and the temperature in the freezer increases slowly.

That is to say, after the heating wire is turned on, since the heating wire heats the refrigerating chamber, the temperature in the refrigerating chamber will increase significantly, but the temperature in the freezing chamber will also increase slowly.

In step S405, when the time point t2 is recorded, the refrigerating sensor senses the temperature q2, and the freezing sensor senses the temperature p2.

That is, the current indoor temperature q2 of the refrigerating chamber detected by the refrigerating sensor and the current indoor temperature p2 of the freezing chamber detected by the freezing sensor at the time point t2 are recorded.

In step S406, through algorithm calculation, A1=(q2-q1)/(t2-t1), A2=(p2-p1)/(t2-t1).

That is to say, according to the indoor temperature of the freezer compartment and the indoor temperature of the refrigerator compartment and the current indoor temperature of the freezer compartment and the current indoor temperature of the refrigerator compartment, the cooling ratio is obtained, and then the action control of the heater is performed in different ratio intervals according to the cooling ratio, The details are as follows, and the preset thresholds are 4.33 and 1.81 as examples for illustration.

In step S407, if (A1/A2)>4.33, execute step S408.

In step S408, the heating wire stops working immediately, and the compressor cools down.

That is to say, when the cooling ratio is greater than 4.33, the heating wire is turned off and the compressor is turned on.

In step S409, if 1.81<(A1/A2)<4.33, execute step S410.

In step S410, the heating wire stops working immediately, the compressor does not work, and the temperature inside the box rises naturally.

That is to say, when the cooling ratio is less than 4.33 and greater than 1.81, the heating wire is turned off and the compressor is turned off.

In step S411, if (A1/A2)<1.81, then step S412 is executed.

In step S412, the heating wire continues to work, and the compressor does not work.

That is to say, when the cooling ratio is less than 1.81, the heating wire is turned on and the compressor is turned off.

According to the control method of the refrigerator according to the embodiment of the present invention, when the refrigerator compartment and the freezer compartment are refrigerated, once the refrigerator compartment is too low, the heating device is controlled to heat the refrigerator compartment, not only keeping the temperature of the freezer compartment in the freezing temperature range, Moreover, the temperature of the refrigerator can be kept in the refrigerator temperature range, so that the refrigerator has the function of refrigeration and freezing at the same time, which greatly improves the convenience of use of the refrigerator and better meets the needs of users. The heating device is controlled by the ratio of the heating rate of the freezing chamber, which improves the reliability of the heating device, better ensures the safety and reliability of the refrigerator, saves energy, and reduces costs.
