The existing refrigerator is generally provided with an air supply port at the rear upper part of a drawer, cold air generated by an evaporator is blown into the drawer to cool the interior of the drawer, the opening of an air door at the air supply port is utilized to adjust the air quantity fed into the interior of the drawer, however, the air supply at the air supply port can cause lower temperature of the part through which air flows, and the temperature of the part positioned at the dead angle of the air flow is higher, so that the temperature distribution in the drawer is uneven, the food preservation is directly influenced, and the problem of poor preservation effect of the refrigerator is caused. To this end, the present application provides a refrigeration apparatus as shown in fig. 1 to 5, comprising: the refrigerator comprises a refrigerator body 1, wherein an ice temperature storage cavity 11 is formed in the refrigerator body 1; the air inlet assembly 2 is arranged in the box body 1, the air inlet assembly 2 is provided with at least two air supply openings 21, and all the air supply openings 21 are communicated with the ice temperature storage cavity 11; the deformation structure 3, deformation structure 3 with supply-air outlet 21 one-to-one, just deformation structure 3 can produce deformation in order to adjust the flow area of corresponding supply-air outlet 21. Through set up a plurality of supply-air inlets 21 on air inlet subassembly 2, can carry out the air supply refrigeration of a plurality of positions to ice temperature storage chamber 11, can only follow the back top air supply of drawer and cause the inhomogeneous problem of drawer inside temperature among the prior art has been overcome, improve the temperature uniformity degree of ice temperature storage chamber 11, set up the flow area of regulation structure to supply-air inlet 21 moreover and adjust for every supply-air inlet 21 homoenergetic carries out independent regulation, realize the independent regulation to the air supply amount of air of the inside different positions of ice temperature storage chamber 11, further improvement ice temperature storage chamber 11's temperature uniformity degree, thereby improve refrigeration plant and refrigerator to the storage reliability of the article that needs ice temperature fresh-keeping.
As an implementation manner, the deformation structure 3 includes a deformation casing and a temperature-sensing deformation material, the deformation casing is disposed at the air supply port 21, the temperature-sensing deformation material is disposed in the deformation casing, and the temperature-sensing deformation material can drive the deformation casing to deform. Because the air supply port 21 can send cold air into the ice temperature storage cavity 11, when the temperature sensing deformation material receives the cold energy of the cold air, the volume of the temperature sensing deformation material changes, thereby driving the volume change of the deformation shell, reducing or increasing the shielding of the deformation shell to the flow area of the air supply port 21, and further increasing or reducing the air supply quantity of the corresponding air supply port 21. For example, when the temperature of the cold air in the air supply port 21 decreases, the temperature-sensitive deformation material can be changed from a liquid state to a solid state, so that the volume is increased, the volume of the deformation shell is further driven to be increased, the flow area of the corresponding air supply port 21 is reduced, the refrigeration effect of the air supply port 21 is reduced, when the temperature of the part of the ice temperature storage cavity 11 corresponding to the air supply port 21 reaches a set value, the air supply port 21 is in a basically closed state, the temperature of the part of the ice temperature storage cavity 11 can be kept stable only by breeze, and the supercooling condition of the continuous air outlet of the fan can not occur; when the cold air temperature of the air supply port 21 increases, the temperature-sensing deformation material can be changed from solid state to liquid state, so that the volume is reduced, the volume of the deformation shell is further driven to be reduced, the flow area of the corresponding air supply port 21 is increased, the refrigerating effect of the air supply port 21 is increased, the independent and automatic adjustment of different refrigerating effects at different positions in the ice temperature storage cavity 11 is realized, the temperature uniformity degree in the ice temperature storage cavity 11 is further improved, and the storage reliability of refrigerating equipment and a refrigerator is improved. Preferably, the temperature range of the ice temperature storage cavity 11 is 0 ℃ +/-0.5 ℃, and the temperature-sensing deformation material comprises a cold storage agent with the phase transition temperature of 0 ℃. When the temperature of the cold air at the air supply port 21 is reduced to 0 ℃, the phase change of the cold storage agent is changed from liquid to solid, the volume is increased, and the flow area of the air supply port 21 is gradually reduced; when the cold air temperature at the air supply port 21 reaches 0 ℃, all cold storage agent annular bags at the air inlets are subjected to phase transition in phase sequence, only breeze can maintain cold energy, and the temperature in the breeze ice temperature storage cavity 11 is maintained stable, so that the supercooling condition of the continuous air outlet of the fan is avoided, and the storage reliability of the refrigeration equipment is further improved.
Specifically, the shape of the deformation shell is annular, the annular central axis is collinear with the central axis of the air supply outlet 21, the annular periphery is attached to the edge of the air supply outlet 21, and the annular inner periphery is adjustable in diameter. Utilize deformation of temperature sensing deformation material, to the extrusion of deformation shell, because deformation shell's periphery is set up on the border of supply-air outlet 21 for deformation shell can't produce deformation on the side of periphery, but can only deform on the side of deformation shell's inner periphery, makes the diameter of inner periphery change, reaches the even regulation to the flow area of supply-air outlet 21, thereby improves the reliable control to supply-air volume and the air supply velocity of flow of supply-air outlet 21.
Or, due to the structure and material limitation of the deformation shell, the annular inner periphery can deform, and at the moment, the deformation of the deformation shell is irregular, but the flow area of the air supply port 21 can be adjusted, so that the air supply quantity of the air supply port 21 is adjusted.
In order to avoid the flow area to supply-air outlet 21 to adjust the back, the temperature uniformity degree in the ice temperature storage chamber 11 is crisscross, refrigeration plant still includes heating mechanism 4, heating mechanism 4 set up in on the deformation structure 3, just heating mechanism 4 can be right deformation structure 3 heats. Utilize heating mechanism 4 to heat deformation structure 3 for all supply-air openings 21 all increase the air supply amount of wind, and quick temperature to the ice temperature in the storage chamber 11 carries out even balance, guarantees the temperature homogeneity of ice temperature storage chamber 11, then disconnection heating mechanism 4, make the air supply amount of wind of supply-air opening 21 carry out independent control through the deformation of temperature sensing deformation material again can. The refrigeration equipment further comprises at least two first temperature detection mechanisms 51, all the first temperature detection mechanisms 51 are uniformly distributed in the ice temperature storage cavity 11, and all the first temperature detection mechanisms 51 are electrically connected with the heating mechanism 4. The temperature detection is performed on different positions in the ice temperature storage cavity 11 by using the first temperature detection mechanism 51, so that whether the temperatures of all the positions in the ice temperature storage cavity 11 are uniform and are within a preset temperature range is judged, if the temperature difference between the two positions is large, the heating mechanism 4 is controlled to work, the temperature uniformity degree in the ice temperature storage cavity 11 is rapidly improved, meanwhile, whether the temperatures of all the positions are within the preset temperature range or not is judged, whether the ice temperature storage cavity 11 is required to be refrigerated or not is judged, and the purpose of whether the air inlet assembly 2 works can be controlled. Preferably, the heating mechanism 4 is an aluminum foil heating wire, and the aluminum foil heating wire is arranged along the arrangement mode of the air supply outlet 21, so that the aluminum foil heating wire can heat all the deformation structures 3, the air quantity is increased for all the air supply outlets, the temperature uniformity in the ice temperature storage cavity 11 is improved rapidly, and the storage reliability of the refrigeration equipment is improved. As shown in fig. 2, the air supply openings 21 are distributed in an array shape, and the aluminum foil heating wires are continuously S-shaped and sequentially bypass all the air supply openings 21, so that all the deformation structures 3 can be heated at the same time.
The air inlet assembly 2 further comprises an air inlet shell, an air inlet cavity 22 is formed in the air inlet shell, all air supply outlets 21 are arranged on the side wall of the air inlet shell, which faces the ice temperature storage cavity 11, and all the air supply outlets 21 are communicated with the air inlet cavity 22. The air inlet cavity 22 is utilized to cache the cold air to be sent into the ice temperature storage cavity 11, so that the air supply quantity of each air supply opening 21 is uniform, and the temperature uniformity degree of the ice temperature storage cavity 11 is further improved. In order to make cold wind enter into the air inlet chamber 22 to can send into ice temperature storage chamber 11 through supply-air inlet 21, air inlet subassembly 2 still includes air inlet fan 23, air inlet fan 23 set up in box 1 or in the air inlet casing, just air inlet fan 23's rotational speed is adjustable, utilizes air inlet fan 23's rotational speed to adjust, controls the cold amount of wind that gets into in the air inlet chamber 22, thereby avoids air inlet fan 23 a large amount of air supply and the flow area reduction of supply-air inlet 21 to cause cold wind to pile up in air inlet chamber 22 and condensation scheduling problem, improves air inlet subassembly 2's reliability and controllability, and then improves refrigeration plant's reliability.
Optionally, the air intake assembly 2 further includes a second temperature detecting mechanism 52, where the second temperature detecting mechanism 52 is disposed in the air intake cavity 22, and the second temperature detecting mechanism 52 is electrically connected to the air intake fan 23. The temperature in the air inlet cavity 22 is obtained by utilizing the second temperature detection mechanism 52, so that the temperature of cold air fed into the ice temperature storage cavity 11 is determined, and when the temperature in the air inlet cavity 22 is matched with the preset temperature range of the ice temperature storage cavity 11, the current working state of the air inlet fan 23 can be kept at the moment, and the reliable storage in the ice temperature storage cavity 11 can be realized; when the temperature in the air inlet cavity 22 is lower (lower than the preset temperature lower limit of the ice temperature storage cavity 11), the temperature sensing deformation mechanism at the air inlet 21 increases the volume to reduce the flow area of the air inlet 21, so that the rotating speed of the air inlet fan 23 needs to be reduced to reduce the air quantity of cold air entering the air inlet cavity 22 in order to avoid cold air accumulation in the air inlet cavity 22; when the temperature in the air inlet cavity 22 is higher (the preset upper temperature limit of the high Yu Bingwen storage cavity 11), the refrigerating effect of the cold air in the air inlet cavity 22 on the ice storage cavity 11 is insufficient, the temperature sensing deformation mechanism at the air supply port 21 also reduces the volume to increase the flow area of the air supply port 21, so that the air supply quantity of the air supply port 21 is satisfied, meanwhile, the temperature of the air inlet cavity 22 needs to be reduced as soon as possible, the rotating speed of the air inlet fan 23 is increased, the cold air is rapidly fed into the air inlet cavity 22, the cold quantity entering the air inlet cavity 22 is improved, and the cooling reliability of the ice storage cavity 11 and the storage reliability of articles are improved.
The refrigeration equipment further comprises a drawer which is movably arranged in the ice temperature storage cavity 11, and the air outlet directions of all the air outlets 21 are directed to the inside of the drawer. The drawer is utilized to facilitate taking and placing of articles, and the use experience of a user is improved.

the T0 is compared with a preset temperature range, and the rotating speed of the air inlet fan 23 is regulated according to the comparison result, so that the air quantity fed into the air inlet cavity 22 by the air inlet fan 23 can be matched with the air quantity fed by the air supply port 21, and the refrigeration reliability of the ice temperature storage cavity 11 is ensured.
If so, the air inlet cavity 22 can reliably and stably refrigerate the ice temperature storage cavity 11, so that the rotating speed of the air inlet fan 23 is kept unchanged, and the current working state of the refrigeration equipment is kept unchanged.
Specifically, if not, adjusting the rotation speed of the air intake 23 includes:
comparing T0 with a maximum value Tmax of a preset temperature range and a minimum value Tmin of the preset temperature range respectively;
if T0 > Tmax, increasing the rotation speed of the air intake 23, when the temperature in the air intake cavity 22 is higher (the preset upper temperature limit of the high Yu Bingwen storage cavity 11), the refrigerating effect of the cold air in the air intake cavity 22 on the ice storage cavity 11 is insufficient, the temperature sensing deformation mechanism at the air supply port 21 also reduces the volume to increase the flow area of the air supply port 21, so that the air supply volume of the air supply port 21 is satisfied, and meanwhile, the temperature of the air intake cavity 22 needs to be reduced as soon as possible, and the rotation speed of the air intake 23 is increased, so that the cold air is fed into the air intake cavity 22 quickly, and meanwhile, the cold amount entering the air intake cavity 22 is improved, and the cooling reliability of the ice storage cavity 11 and the storage reliability of articles are improved;
if Tmax is more than or equal to T0 and more than or equal to Tmin, the rotating speed of the air inlet fan 23 is kept unchanged;
if Tmin > T0, the rotation speed of the air intake 23 is reduced, and when the temperature in the air intake chamber 22 is low (lower than the preset temperature lower limit of the ice temperature storage chamber 11), the temperature sensing deformation mechanism at the air intake 21 increases the volume to reduce the flow area of the air intake 21, so that the rotation speed of the air intake 23 needs to be reduced to avoid cold air accumulation in the air intake chamber 22, and the air volume of cold air entering the air intake chamber 22 needs to be reduced.
Wherein, the relation between the maximum value Tmax in the preset temperature range and the preset upper temperature limit T1 of the ice temperature storage chamber 11 is: tmax=t1+a, a is a calculation constant, preferably a is 0.5 ℃;
or, the relationship between the minimum value Tmin in the preset temperature range and the preset temperature lower limit T2 of the ice temperature storage chamber 11 is: tmax=t2-a, a being a calculation constant.
For example, the preset temperature value of the ice temperature storage chamber 11 is 0 ℃ ±0.5 ℃. When the second temperature detecting mechanism 52 in the air intake cavity 22 detects that the temperature of the air intake cavity 22 is greater than-1 ℃ and less than 0 ℃, the rotation speed of the air intake fan 23 is adjusted to be V1. When the second temperature detection mechanism 52 positioned in the air inlet cavity 22 detects that the temperature of the air inlet cavity 22 is higher than 0 ℃, the rotating speed of the air inlet fan 23 is regulated to V2 (V2 is more than V1); when the second temperature detecting mechanism 52 in the air inlet cavity 22 detects that the temperature of the air inlet cavity 22 is less than minus 1 ℃, the air inlet fan 23 is closed. The temperature in the ice temperature storage cavity 11 slowly rises, the cold storage agent is gradually melted into liquid, and the air supply port 21 is opened again for refrigeration.
The refrigeration equipment further comprises a heating mechanism 4, the heating mechanism 4 is arranged on the deformation structure 3, the heating mechanism 4 can heat the deformation structure 3, and the control method further comprises the following steps:
acquiring the temperature uniformity degree in the ice temperature storage cavity 11;
if the temperature in the ice temperature storage chamber 11 is not uniform, the heating mechanism 4 is controlled to operate. The temperature detection is performed on different positions in the ice temperature storage cavity 11 by using the first temperature detection mechanism 51, so that whether the temperatures of all the positions in the ice temperature storage cavity 11 are uniform and are within a preset temperature range is judged, if the temperature difference between the two positions is large, the heating mechanism 4 is controlled to work, the temperature uniformity degree in the ice temperature storage cavity 11 is rapidly improved, meanwhile, whether the temperatures of all the positions are within the preset temperature range or not is judged, whether the ice temperature storage cavity 11 is required to be refrigerated or not is judged, and the purpose of whether the air inlet assembly 2 works can be controlled. Wherein the duration of the operation of the heating mechanism 4 ranges from 5s to 20s, preferably 10s, so that the influence of the temperature in the ice temperature storage cavity 11 caused by the overlong operation time of the heating mechanism 4 is avoided.
A refrigerator comprises the refrigerating equipment or a control method applying the refrigerating equipment.
