The present refrigerator generally further includes a refrigeration system comprising a compressor, a condenser, and an evaporator 40, wherein the refrigerant can partially evaporate and absorb heat in the evaporator 40 to remove heat around the evaporator 40. After the temperature around the evaporator 40 is reduced, the fan 50 blows cool air to the storage cavity 12 of the box body 10 through the air duct, so that the temperature in the storage cavity 12 is reduced, and the effect of preserving the articles stored in the storage cavity 12 by a user is achieved. Accordingly, a general refrigerator is also provided with a duct board 20 having a duct structure in which a duct is used to communicate a blower 50 and a storage chamber 12, and the blower 50 can blow cool air around an evaporator 40 into the storage chamber 12 through the duct.

In the conventional refrigerator, an air outlet is generally provided in the duct board 20 and cool air is blown into the storage chamber 12 through the air outlet. However, the existing air outlet of the refrigerator cannot guide the cool air blown into the storage cavity 12, which results in that the air supply direction of the blower 50 cannot be controlled, and the air flow in the cavity may be disturbed, so that the air supply effect of the refrigerator is poor.

As shown in fig. 1 to 5, the embodiment of the present disclosure provides a refrigeration apparatus that can guide cool air blown into a storage cavity 12 through an air duct, and has a better air blowing effect.

As shown in fig. 1 to 5, the embodiment of the present disclosure provides a refrigeration apparatus including an evaporator 40, and further including a cabinet 10, an air duct board 20, and an air deflector group. The case 10 includes a storage chamber 12 and a mounting chamber 13, the mounting chamber 13 being used for mounting the evaporator 40; the air duct plate 20 is arranged in the storage cavity 12 and comprises an air supply duct 23 communicated with the installation cavity 13 and a first air outlet 21 arranged on the side wall surface of the air duct plate, and the first air outlet 21 is used for communicating the air supply duct 23 with the storage cavity 12; the air deflector group comprises first air deflector plates 31 obliquely arranged at the first air outlet 21; the air in the installation cavity 13 can flow into the storage cavity 12 through the air outlet duct and the first air outlet 21, and the first air deflector plate 31 can guide the air flowing into the storage cavity 12.

Specifically, the evaporator 40 is fixedly installed in the installation cavity 13 of the case 10, and the evaporator 40 is used for refrigerating the surrounding air flow. The installation cavity 13 is provided with a connecting air duct 14, and the connecting air duct 14 is used for communicating the installation cavity 13 with the air supply air duct 23. The first air outlet 21 is disposed on the left side wall surface and/or the right side wall surface of the air duct board 20. After the evaporator 40 cools the surrounding air, the cool air can flow into the air supply duct 23 through the connecting duct 14, and then the cool air in the air supply duct 23 is conveyed into the storage cavity 12 through the first air outlet 21, so as to cool the storage cavity 12. When the cool air flows through the first air outlet 21, the first air deflector 31 can deflect the cool air flowing through the first air outlet 21, so as to improve the air supply effect.

As shown in fig. 2, the refrigeration appliance optionally also includes a blower 50. The fan 50 is fixedly arranged in the mounting cavity 13 and comprises an air outlet end which is arranged corresponding to the connecting air duct 14. After the evaporator 40 cools the surrounding air, the fan 50 may blow cool air into the supply air duct 23 through the connection air duct 14. By this arrangement, the efficiency of the air circulation of the refrigeration equipment can be increased.

As shown in fig. 1, the case 10 is optionally further provided with an opening 11, through which a user can access the articles in the storage chamber 12. The air duct board 20 is fixedly installed on the side of the storage cavity 12 away from the opening 11, so as to prevent the air flow blown by the fan 50 from being blown to the user.

As shown in fig. 2, the mounting cavity 13 is optionally further provided with a return air duct 15, and the return air duct 15 is used for communicating the mounting cavity 13 with the storage cavity 12. Wherein the return air duct 15 is disposed on the other side of the evaporator 40 with respect to the blower 50. Air in the storage cavity 12 can flow into the installation cavity 13 through the return air duct so as to realize air flow circulation.

As shown in fig. 2, optionally, a return air duct 15 is provided on the side of the mounting cavity 13 adjacent to the opening 11. The fan 50 can blow the cool air around the evaporator 40 into the storage cavity 12 through the air supply duct 23 and the first air outlet 21, and then suck the air in the storage cavity 12 into the installation cavity 13 through the return air duct 15. The return air duct 15 is disposed on the side of the installation cavity 13 near the opening 11, so that the cold air flow blown out from the first air outlet 21 flows through the articles stored in the storage cavity 12 and then flows into the installation cavity 13 through the return air duct 15.

In some implementations, the refrigeration equipment includes an evaporator 40, a fan 50, a cabinet 10, a duct board 20, and an air deflection assembly. The case 10 includes a storage chamber 12 and a mounting chamber 13, and the mounting chamber 13 is disposed above the storage chamber 12. The storage cavity 12 is also provided with an opening 11 and a back plate arranged opposite to the opening 11, and the air duct plate 20 is fixedly arranged on the back plate. The air duct plate 20 is provided with an air supply duct 23 and a first air outlet 21 which are communicated with the storage cavity 12, and the mounting cavity 13 is also provided with a connecting air duct 14 which is communicated with the air supply duct 23. The air deflector group comprises a first air deflector sheet 31 fixedly arranged at the first air outlet 21, and the first air deflector sheet 31 is obliquely arranged. The evaporator 40 and the fan 50 are fixedly installed in the installation cavity 13, and the fan 50 is arranged between the evaporator 40 and the connecting air duct 14. After the evaporator 40 cools the surrounding air, the fan 50 can blow the cool air into the air supply duct 23 through the connecting duct 14, and then the cool air in the air supply duct 23 flows into the storage cavity 12 through the first air outlet 21 to cool the storage cavity 12. It will be appreciated that, since the cool air spontaneously flows downward, the installation cavity 13 is disposed above the storage cavity 12, so that the cool air is more beneficial to flow into the storage cavity 12 through the connecting air duct 14, the air supply air duct 23 and the first air outlet 21 in sequence.

In some embodiments, the included angle between the first air deflector sheet 31 and the horizontal plane is greater than or equal to a first preset angle and less than or equal to a second preset angle.

Specifically, the included angle of the first air deflector sheet 31 in the horizontal plane is the first included angle θ. The first preset angle is 15 degrees, and the second preset angle is 75 degrees, that is, the first included angle θ is greater than or equal to 15 degrees and less than or equal to 75 degrees. By this arrangement, the cool air in the air supply duct 23 can flow into the storage chamber 12 more gently and smoothly.

It will be appreciated that if the first included angle θ is smaller than 15 °, the air in the air supply duct 23 may directly impinge on the first air deflector sheet 31, which may affect the air supply effect. If the first included angle θ is greater than 75 °, the first air deflection sheet 31 may not function to guide the air flow flowing through the first air outlet 21.

As shown in fig. 4, in some embodiments, the first air deflection plate 31 includes a first end connected to the first air outlet 21 and a second end extending toward the supply air duct 23; wherein the height of the second end of the first wind guiding plate 31 is higher than the height of the first end.

Specifically, the first air deflector sheet 31 includes a first end and a second end that are disposed opposite to each other, the first end of the first air deflector sheet 31 is fixedly connected to the edge of the first air outlet 21, and the second end of the first air deflector sheet 31 extends into the air supply duct 23. Wherein the height of the second end of the first wind guiding plate 31 is higher than the height of the first end. Since the installation chamber 13 is disposed above the storage chamber 12, the cool air in the air supply duct 23 flows from top to bottom in the air supply duct 23. When the cool air flows to the first air outlet 21 and impacts the first air deflector sheet 31, the cool air flows from the second end of the first air deflector sheet 31 to the first end of the first air deflector sheet 31 along the upper wall surface of the first air deflector sheet 31, and flows into the storage cavity 12 through the first air outlet 21.

In the above embodiment, the height of the first end of the first air guiding plate 31 refers to the distance from the first end of the first air guiding plate 31 to the ground, and the height of the second end of the first air guiding plate 31 refers to the distance from the second end of the first air guiding plate 31 to the ground.

In some embodiments, the second end of the first air deflection sheet 31 extends toward the supply air duct 23 a distance greater than or equal to a predetermined distance.

Specifically, the second end of the first air deflector sheet 31 extends toward the air supply duct 23 by a first distance L. Wherein the first distance L is greater than or equal to 1cm. For example, the first distance L may be 1cm, 2cm or 3cm. By this arrangement, the flow guiding range of the first air guiding plate 31 can be increased.

In the above embodiment, the distance that the second end of the first air deflection sheet 31 extends toward the air supply duct 23 refers to the distance from the second end to the first end of the first air deflection sheet 31.

In some embodiments, the first air outlet 21 includes a plurality of air outlet portions, and the plurality of air outlet portions are disposed vertically; the first air guiding plate 31 is disposed between the air outlet portions to separate the air outlet portions.

Specifically, the first air deflector sheet 31 is disposed between the plurality of air outlet portions, so that the air flow flowing through the first air outlet 21 flows into the storage cavity 12 through the plurality of air outlet portions, thereby realizing the effect of air flow layering and further improving the air supply effect.

In some practical applications, the first air outlet 21 includes a first air outlet portion and a second air outlet portion. The air deflector group comprises a first air deflector sheet 31, and the first air deflector sheet 31 is arranged between the first air outlet portion and the second air outlet portion to separate the first air outlet portion and the second air outlet portion. In this way, the air flow at the first air outlet 21 can flow into the storage cavity 12 through the first air outlet portion and the second air outlet portion respectively.

In other practical applications, the first air outlet 21 includes a first air outlet portion, a second air outlet portion, and a third air outlet portion. The air deflector group comprises two first air deflector plates 31, and the two first air deflector plates 31 are respectively arranged between the first air outlet portion and the second air outlet portion and between the second air outlet portion and the third air outlet portion so as to separate the first air outlet portion, the second air outlet portion and the third air outlet portion. In this way, the air flow at the first air outlet 21 can flow into the storage cavity 12 through the first air outlet portion, the second air outlet portion and the third air outlet portion respectively.
