Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of refrigerator temperature-changing chamber control method, described refrigerator comprises refrigerating chamber, refrigerating chamber and temperature-changing chamber, alternating temperature air door is provided with between described temperature-changing chamber and described refrigerating chamber, when described alternating temperature door opening, air in described refrigerating chamber and described temperature-changing chamber carries out convection current by described alternating temperature air door, thus described temperature-changing chamber is freezed, as shown in Figure 1, described method comprises:
101, when the temperature of described temperature-changing chamber is more than or equal to the open temp of described alternating temperature air door, obtain the first difference, described first difference is the difference between the Current Temperatures of described temperature-changing chamber and the temperature of described refrigerating chamber.
The method that the embodiment of the present invention provides can be applied in the side by side combination refrigerator of single refrigeration system.Wherein, the open temp of alternating temperature air door is default.
Optionally, the method can also comprise: the current function gear obtaining described temperature-changing chamber, according to the open temp of described current function gear determination alternating temperature air door.
Generally, temperature-changing chamber has multiple function gear, each corresponding temperature range of each function gear, in the temperature range that the current function gear that the temperature in temperature-changing chamber needs to remain on temperature-changing chamber is corresponding.Wherein, the open temp of a corresponding alternating temperature air door of function gear and closing temperature, the open temp of alternating temperature air door can be the maximum temperature values in temperature range that this function gear is corresponding, and the closing temperature of alternating temperature air door can be the minimum temperature value in temperature range that this function gear is corresponding.When the temperature of temperature-changing chamber is more than or equal to the open temp of alternating temperature air door, illustrate that the temperature of temperature-changing chamber is too high, need to freeze to temperature-changing chamber.The open temp of the alternating temperature air door in the embodiment of the present invention and closing temperature can be open temp and the closing temperature of the alternating temperature air door that the current function gear of temperature-changing chamber is corresponding.
Step 101 comprises when specific implementation: obtain the Current Temperatures of temperature-changing chamber and the temperature of refrigerating chamber, according to the Current Temperatures of temperature-changing chamber and temperature computation first difference of refrigerating chamber.The Current Temperatures of temperature-changing chamber can be obtained by the temperature sensor be placed in temperature-changing chamber, and the temperature of refrigerating chamber also can be obtained by the temperature sensor be placed in refrigerating chamber.
102, according to described first difference determination angle on target; Wherein, described first difference is larger, and described angle on target is less.
Concrete, step 102, when specific implementation, at least can be realized by following two kinds of modes:
Mode one, pre-set a standard angle, after acquisition first difference, determine an angle adjustment value according to the first difference, be added with angle adjustment value by standard angle and obtain angle on target, wherein, standard angle can pre-set, when first difference is larger, angle adjustment value is less.
Mode two, the temperature range determining belonging to the first difference, the temperature range determination angle on target belonging to the first difference; Wherein, temperature range has multiple, a corresponding angle on target of temperature range.
Exemplary, suppose that the first difference changes between [5 DEG C ~ 35 DEG C], then [5 DEG C ~ 35 DEG C] can be divided into three temperature ranges, the 1st temperature range is [5 DEG C ~ 15 DEG C], and corresponding angle on target is 45 °; 2nd temperature range be (15 DEG C ~ 25 DEG C], corresponding angle on target is 40 °; 3rd temperature range be (25 DEG C ~ 35 DEG C], corresponding angle on target is 35 °.In this situation, when the first difference is in different temperature ranges, the angle on target determined is as shown in table 1.
Table 1
| Temperature range residing for first difference | Angle on target |
| [5℃～15℃] | 45° |
| (15℃～25℃] | 40° |
| (25℃～35℃] | 35° |
103, the angle of described alternating temperature air door is opened to described angle on target.
Concrete; when determining to open alternating temperature air door; signal can be sent to the controller in refrigerator; controller is made to open alternating temperature air door; and do not need to carry out temperature control by frequently opening compressor; therefore, the method that the embodiment of the present invention provides can not increase the startup-shutdown number of times of compressor, extends the life-span of compressor.
Due to when freezing to temperature-changing chamber, be carry out convection current realization by the air in refrigerating chamber and the air in temperature-changing chamber, so when the first difference is larger, the refrigerating speed of temperature-changing chamber is faster, when the first difference more hour, the refrigerating speed of temperature-changing chamber is slower.Therefore, when the first difference is larger, what angle on target can be arranged is less, and when the first difference is less, what angle on target can be arranged is larger.
The method that the embodiment of the present invention provides, according to the first difference determination angle on target, and the angle of opening alternating temperature air door is to angle on target.When the first difference is less, what angle on target can be arranged is larger, to increase the circulation of the air-flow between temperature-changing chamber and refrigerating chamber, to temperature-changing chamber fast-refrigerating, improve the refrigerating efficiency of temperature-changing chamber, when alternating temperature air door closed by needs, because the first difference is less, in the process of closing alternating temperature air door, the temperature fluctuation in temperature-changing chamber also can not be made too large; When the first difference is larger, what angle on target can be arranged is less, is realizing, under the prerequisite to temperature-changing chamber fast-refrigerating, to close timely, the temperature fluctuation in temperature-changing chamber also can not be made too large when alternating temperature air door being closed by needs.
Optionally, described temperature-changing chamber is positioned at described refrigerating chamber, before step 102, described method can also comprise: when the temperature of described temperature-changing chamber is more than or equal to the open temp of described alternating temperature air door, obtain the second difference, described second difference is the difference between the Current Temperatures of described temperature-changing chamber and the temperature of described refrigerating chamber; In this situation, step 102 specifically comprises: according to described first difference and described second difference determination angle on target; Wherein, if described first difference is fixed, when described second difference is larger, described angle on target is less.

1, by first object angle and w
1the second angle on target obtained after addition is defined as angle on target.Wherein, when the second difference is larger, w
1less, w
1can be on the occasion of, negative value and 0.
Wherein, because temperature-changing chamber is positioned at refrigerating chamber, when the second difference be on the occasion of time, the temperature of temperature-changing chamber is greater than the temperature of refrigerating chamber, temperature-changing chamber heats up comparatively slow, and so temperature-changing chamber refrigerating speed is very fast, in this situation, the basis of first object angle can suitably reduce certain angle and obtain the second angle on target, w
1for negative value; When the second difference is negative value, the temperature of temperature-changing chamber is less than the temperature of refrigerating chamber, and temperature-changing chamber heats up very fast, and so temperature-changing chamber refrigerating speed is comparatively slow, in this situation, the basis of first object angle can suitably increase certain angle and obtain the second angle on target, w
1for on the occasion of.
Exemplary, as shown in table 2, with the second difference when different temperature ranges, w
1value be not all example, suppose that the second difference changes between [-20 DEG C ~ 10 DEG C], then this temperature range can be divided into three temperature ranges, the 1st temperature range is [-20 DEG C ~-10 DEG C], corresponding w
1=5 °; 2nd temperature range be (-10 DEG C ~ 0 DEG C], corresponding w
1=0 °; 3rd temperature range be (0 DEG C ~ 10 DEG C], corresponding w
1=-5 °.When the second difference is the 1st temperature range, first object angle is increased by 5 ° and can obtain the second angle on target, when the second difference is the 2nd temperature range, first object angle is increased by 0 ° and can obtain the second angle on target, when the second difference is the 3rd temperature range, first object angle is reduced 5 ° and can obtain the second angle on target.In this situation, based on the example described in table 1, if the temperature range residing for the first difference be (15 DEG C ~ 25 DEG C], the angle on target determined when the second difference is in different temperature ranges can be as shown in table 3.
Table 2
| Temperature range | w 1 |
| [-20℃～-10℃] | 5° |
| (-10℃～0℃] | 0° |
| (0℃～10℃] | -5° |

| [-20℃～-10℃] | 45 |
| (-10℃～0℃] | 40 |
| (0℃～10℃] | 35 |
It should be noted that, because the first difference of mentioning in the embodiment of the present invention and the second difference are temperature difference, therefore, in the description of the embodiment of the present invention, the first difference and the second difference have all been with temperature unit DEG C, but, the first difference mentioned in the embodiment of the present invention and the size of the second difference size only in exponential quantity, such as, when the first difference is the first numerical value and second value and the first numerical value is-5, when second value is-10, the first numerical value is greater than second value.
Optionally, before step 102, described method also comprises: when the temperature of described temperature-changing chamber is more than or equal to the open temp of described alternating temperature air door, obtain the temperature of the external environment condition residing for described refrigerator; In this situation, step 102 specifically comprises: the temperature determination angle on target of the external environment condition residing for described first difference and described refrigerator; Wherein, if described first difference is fixed, when the temperature of the external environment condition residing for described refrigerator is larger, described angle on target is larger.

2larger, w
2can be on the occasion of, negative value and 0.
When the ambient temperature residing for refrigerator is higher, temperature in refrigerating chamber is very fast, because temperature-changing chamber is positioned at refrigerating chamber, and then the speed causing temperature-changing chamber to heat up, make temperature-changing chamber refrigerating speed slower, therefore, in this situation, the basis of first object angle suitably can increase certain angle and obtain the 3rd angle on target, to increase the circulation of the air-flow between temperature-changing chamber and refrigerating chamber, to temperature-changing chamber fast-refrigerating, w
2for on the occasion of.Same principle, when the ambient temperature residing for refrigerator is lower, w
2it can be negative value or 0.
Exemplary, as shown in table 4, with the temperature of the external environment condition residing for refrigerator when different temperature ranges, w

2=5 °; Second temperature range is [0 DEG C ~ 30 DEG C], corresponding w
2=0 °.When the temperature of the external environment condition residing for refrigerator is the 1st temperature range, first object angle is increased by 5 ° and can obtain the 3rd angle on target, when the temperature of external environment condition is the 2nd temperature range, first object angle is increased by 0 ° and can obtain the 3rd angle on target.In this situation, based on the example described in table 1, if the temperature range residing for the first difference be (15 DEG C ~ 25 DEG C], when the temperature of the external environment condition residing for refrigerator is in different temperature ranges, the angle on target determined can be as shown in table 5.
Table 4
| Temperature range | w 2 |
| (30℃～43℃] | 5° |
| [0℃～30℃] | 0° |
Table 5
| Temperature range residing for the temperature of the external environment condition residing for refrigerator | Angle on target |

| [0℃～30℃] | 40° |
Said method, can also the temperature determination angle on target of external environment condition residing for the first difference, the second difference and refrigerator when specific implementation.Concrete, first according to the first difference determination first object angle, first object angle can be increased w

2obtain the 3rd angle on target, using the 3rd angle on target as angle on target.Wherein, w
1for the angle adjustment value determined according to the second difference, w
2for the angle adjustment value that the temperature of the external environment condition residing for refrigerator is determined.
In this situation, based on the example described in table 1, table 2 and table 4, for the temperature range residing for the first difference for (15 DEG C ~ 25 DEG C] be described, the temperature of the second difference and the external environment condition residing for refrigerator is when different temperature ranges, and the angle on target determined can be as shown in table 6.
