[0036] In the related art, the air outlet channel of the refrigeration equipment is provided with a fan to make the cooled gas in the heat exchange chamber flow to the storage chamber, so as to cool the articles in the storage chamber. Usually, the number of fans in a single air outlet channel is single. The air volume provided by a single fan is limited, and the flow rate of the cooled gas in the process of flowing from the heat exchange chamber to the storage chamber is slow, so that the gas may absorb more heat during the flow process, resulting in temperature rise, and thus affecting the cooling effect of the gas on the articles in the storage chamber.

[0037] The number of the fans 300 is at least two, and the multiple fans 300 can provide a larger air volume, so that the cooled gas can flow from the heat exchange chamber 100b to the storage chamber more quickly, thereby reducing the degree of temperature rise of the gas and improving the refrigeration capacity of the refrigeration equipment.

[0038] The present application provides a refrigeration equipment, please refer to Figures 1 to 5 The refrigeration equipment includes a cabinet 100, an evaporator 200 and at least two fans 300. As shown in Figure 5 The cabinet 100 is internally provided with a storage chamber, a heat exchange chamber 100b and an air outlet passage 100a. The heat exchange chamber 100b is located at the bottom of the storage chamber, and the air outlet passage 100a is in communication with the storage chamber and the heat exchange chamber 100b, respectively. The evaporator 200 is arranged in the heat exchange chamber 100b, and is used for cooling the gas. The fans 300 are located in the same air outlet passage 100a, and the fans 300 are installed on the cabinet 100. The fans 300 are used for blowing the gas cooled by the evaporator 200 to the storage chamber. The number of the fans 300 is at least two.

[0039] The storage chamber refers to a chamber for storing articles. The storage chamber can be provided with storage drawers, and the user can store or take the articles by pulling the storage drawers. The number of the storage drawers can be multiple, and the multiple storage drawers are arranged in the up-down direction to divide the storage chamber.

[0040] Exemplarily, the refrigeration equipment can be a refrigerator or a freezer.

[0041] Exemplarily, the fan 300 is a centrifugal fan 300. The rotational axis direction of the fan 300 is arranged orthogonally to the height direction of the air outlet passage 100a, wherein the height direction of the air outlet passage 100a is the vertical direction. In the working process, the fan 300 can draw the gas in the heat exchange chamber 100b to the air outlet passage 100a, and the gas moves upward along the air outlet passage 100a in the vertical direction until it moves to the joint of the air outlet passage 100a and the storage chamber, and then moves into the storage chamber.

[0042] In this embodiment of the application, the refrigeration equipment is equipped with at least two fans 300 at the air outlet duct 100a. During the operation of the refrigeration equipment, the multiple fans 300 can blow the gas cooled by the evaporator 200 into the storage chamber. The multiple fans 300 can provide a large air volume, and the gas flow velocity in the air outlet duct 100a is relatively fast, thereby blowing the cooled gas into the storage chamber as quickly as possible. The cooled gas has a short residence time in the heat exchange chamber 100b and the air outlet duct 100a, and the gas enters the storage chamber before its temperature rises to a high level, resulting in a better cooling effect of the refrigeration equipment. Furthermore, the fact that the heat exchange chamber 100b is located at the bottom of the storage chamber reduces the space occupied by the heat exchange chamber 100b in the storage chamber, thereby maximizing the space of the storage chamber and improving the user experience.

[0043] In one embodiment, please refer to Figure 2 Multiple 300 fans are arranged at intervals along the horizontal direction.

[0044] For example, the arrangement direction of the multiple fans 300 is a first direction, which is orthogonal to the vertical direction. The vertical direction is as follows: Figure 3 The direction indicated by the middle arrow R1, the first direction is as follows: Figure 3 The direction indicated by the middle arrow R3.

[0045] In the embodiment of this application, the fans 300 are arranged at intervals along the horizontal direction, and the airflow generated by the multiple fans 300 can be distributed relatively evenly along the horizontal direction. Moreover, the multiple fans 300 can make full use of the horizontal arrangement space of the housing 100, reducing the interference between the multiple fans 300 and other components of the refrigeration equipment.

[0046] It is understood that other embodiments of this application are not limited to the arrangement of multiple fans 300 spaced apart in a horizontal direction. Exemplarily, the multiple fans 300 are arranged spaced apart in a vertical direction.

[0047] In one embodiment, when the width of the refrigeration equipment in the horizontal direction ranges from 800mm to 980mm, the horizontal spacing between two adjacent fans 300 arranged in the horizontal direction ranges from 165mm to 190mm.

[0048] For example, the spacing between two adjacent fans 300 is 165mm, 168mm, 170mm, 175mm, 180mm, 183mm or 190mm.

[0049] Understandably, the distance between two adjacent fans 300 can be measured with a ruler under normal temperature and pressure conditions.

[0050] It is understandable that the spacing between two adjacent fans 300 is related to the width dimension of the refrigeration equipment. The larger the width dimension of the refrigeration equipment, the wider the corresponding air outlet duct 100a, and thus the larger the spacing between two adjacent fans 300 needs to be to reduce dead airflow angles. The embodiments of this application do not limit the width of the refrigeration equipment. For example, when the width dimension of the refrigeration equipment is 890mm, the spacing between two adjacent fans 300 ranges from 168mm to 175mm. When the width dimension of the refrigeration equipment is 905mm, the spacing between two adjacent fans 300 ranges from 183mm to 190mm.

[0051] For example, the spacing between two adjacent wind turbines 300 is as follows: Figure 3 As shown in the medium dimension D1.

[0052] In the embodiment of this application, the spacing between two adjacent fans 300 is within a suitable range, which can reduce the mutual interference between the fans 300 and the amount of wind noise generated. Furthermore, the spacing between the fans 300 can make the wind force generated by the fans 300 more uniform along the width direction, and the cooled gas can enter the storage chamber more uniformly, which can reduce the occurrence of uneven cooling in the storage chamber.

[0053] It is understood that other embodiments of this application do not limit the size of the spacing between two adjacent fans 300.

[0054] In one embodiment, please refer to Figure 2 and Figure 3 The housing 100 also has a guide portion 100c, which is located in the air outlet duct 100a. The distance between the guide portion 100c and the fan 300 in the horizontal direction gradually decreases from top to bottom.

[0055] For example, the guide section 100c and the fan 300 are arranged in a basically horizontal direction.

[0056] In the embodiment of this application, the housing 100 has a guide portion 100c. During the operation of the fan 300, gas flows from the heat exchange chamber 100b to the air outlet channel 100a. The gas can be blown towards the guide portion 100c by the fan 300, and the guide portion 100c has a guiding effect on the flow of gas, thereby further accelerating the flow of gas to the storage chamber.

[0057] In one embodiment, please refer to Figure 2The housing 100 includes a first cover plate 110 and a second cover plate 120 connected to each other. The first cover plate 110 and the second cover plate 120 form an air outlet channel 100a. The first cover plate 110 has an air inlet 110a and an air outlet 110b. The air inlet 110a is connected to the heat exchange chamber 100b and the air outlet channel 100a respectively. The air outlet 110b is connected to the air outlet channel 100a and the storage chamber respectively.

[0058] For example, the first cover plate 110 and the second cover plate 120 are arranged along a second direction, which is orthogonal to both the first direction and the vertical direction. The second direction is as follows: Figure 2 , Figure 5 The direction indicated by the middle arrow R2.

[0059] For example, the air inlet 110a and the air outlet 110b are arranged vertically, with the air inlet 110a located below the air outlet 110b. The gas in the heat exchange chamber 100b enters the air outlet channel 100a from the air inlet 110a, and then enters the storage chamber from the air outlet channel 100a through the air outlet 110b, resulting in relatively smooth gas flow.

[0060] For example, the guide portion 100c spans across the first cover plate 110 and the second cover plate 120.

[0061] In the embodiment of this application, the first cover plate 110 and the second cover plate 120 are arranged to form an air outlet channel 100a. The first cover plate 110 and the second cover plate 120 can guide the gas passing through the air inlet 110a so that the gas can flow from the air inlet 110a to the air outlet 110b more quickly, thereby increasing the cooling capacity of the refrigeration equipment.

[0062] It is understood that other embodiments of this application do not limit the specific structure of the housing 100.

[0063] In one embodiment, please refer to Figure 2 The fan 300 includes a fan body 310 and a bracket 320. The bracket 320 is mounted on the second cover plate 120, and the fan 300 is mounted on the corresponding bracket 320. When the fan 300 is mounted on the second cover plate 120, the axial direction of the fan 300 is perpendicular to the large surface of the second cover plate 120, the contact area between the fan 300 and the second cover plate 120 is large, and the connection strength between the fan 300 and the second cover plate 120 is high.

[0064] In one embodiment, please refer to Figure 2 and Figure 5 The housing 100 also includes a return air hood 140, in which a heat exchange chamber 100b is formed. The return air hood 140 is used to receive gas flowing out of the storage chamber so that the high-temperature gas can be cooled by the evaporator 200. The return air hood 140 is located on the side of the first cover plate 110 opposite to the second cover plate 120.

[0065] In one embodiment, the housing 100 further includes a shell 150 located outside the return air hood 140, the first cover plate 110, and the second cover plate 120.

[0066] In one embodiment, the number of air inlets 110a corresponds to the number of fans 300, and the axial direction of the air inlets 110a coincides with the axial direction of the corresponding fans 300.

[0067] For example, when projected along the axial direction of the air inlet 110a, the projection areas of the air inlet 110a and the fan 300 are substantially circular. The projection area of ​​the air inlet 110a coincides with the corresponding projection area of ​​the fan 300.

[0068] In the embodiment of this application, the number of air inlets 110a corresponds to the number of fans 300. Multiple air inlets 110a can increase the area connecting the heat exchange chamber 100b and the air outlet 100a, making the process of gas entering the air outlet 100a from the heat exchange chamber 100b smoother, thereby further improving the cooling capacity of the refrigeration equipment.

[0069] It is understood that other embodiments of this application are not limited to the number of air inlets 110a corresponding to the number of fans 300. For example, the number of air inlets 110a may be one, two, or three.

[0070] In one embodiment, please refer to Figure 2 and Figure 3 The air outlet 110b includes a first air outlet 110c and a second air outlet 110d. The second air outlet 110d is located on the side of the first air outlet 110c facing the fan 300, and the air outlet area of ​​the second air outlet 110d is smaller than the air outlet area of ​​the first air outlet 110c.

[0071] In the embodiment of this application, the second air outlet 110d is located on the side of the first air outlet 110c facing the fan 300. The second air outlet 110d is closer to the fan 300 than the first air outlet 110c, resulting in a faster airflow velocity when it reaches the second air outlet 110d. Furthermore, the smaller air outlet area of ​​the second air outlet 110d compared to the first air outlet 110c ensures that the airflow volume at the first air outlet 110c is substantially the same as that at the second air outlet 110d, thereby making the cooling capacity at the first air outlet 110c substantially the same as that at the second air outlet 110d.

[0072] For example, the dimensions of the first air outlet 110c are 104mm*18.5mm, and the dimensions of the second air outlet 110d are 76mm*16mm. By using the above dimensions, while ensuring that the air volume of the first air outlet 110c and the second air outlet 110d is basically the same, it is also possible to reduce the wind noise and wind resistance at the air outlet 110b.

[0073] For example, the distance between the first air outlet 110c and the second air outlet 110d in the vertical direction ranges from 76mm to 80mm. The distance between the first air outlet 110c and the second air outlet 110d is as follows: Figure 3 As shown in the medium dimension D4.

[0074] For example, along the vertical direction, the distance between the first air outlet 110c and the second air outlet 110d is related to the distance between the corresponding storage drawers. The distance between storage drawers refers to the distance between the mid-planes of two adjacent storage drawers along the vertical direction. If the distance between adjacent storage drawers is large, the distance between the first air outlet 110c and the second air outlet 110d also needs to be increased accordingly. For example, the distance between the first air outlet 110c and the second air outlet 110d may be 76mm, 78mm, or 80mm.

[0075] Understandably, the number of storage drawers corresponds to the number of layers of the air vent 110b. For example, there are two storage drawers, both located in storage compartments, arranged vertically, with the upper drawer having a first storage compartment and the lower drawer having a second storage compartment.

[0076] For example, the air outlet 110b also includes a third air outlet, which is located below the second air outlet 110d, and the number of corresponding storage drawers is three, with the three storage drawers corresponding to the three air outlets.

[0077] For example, the storage drawer is provided with a vent that is connected to the air outlet 110b, thereby allowing cooling gas to enter the interior of the storage drawer.

[0078] It is understood that other embodiments of this application are not limited to the air outlet 110b including a first air outlet 110c and a second air outlet 110d arranged in a vertical direction. Exemplarily, the air outlet 110b includes only the first air outlet 110c. Cooling gas can pass through the first air outlet 110c to cool the entire storage compartment.

[0079] In one embodiment, please refer to Figure 3The number of first air outlets 110c is at least two, and multiple first air outlets 110c are arranged at intervals in the horizontal direction, and / or the number of second air outlets 110d is at least two, and multiple second air outlets 110d are arranged at intervals in the horizontal direction.

[0080] For example, a plurality of first air outlets 110c and / or second air outlets 110d are arranged at intervals along a third direction R3.

[0081] In the embodiments of this application, the number of first air outlets 110c and / or second air outlets 110d is at least two. The arrangement of multiple air outlets 110b at horizontal intervals allows for a more uniform distribution of gas within the storage chamber corresponding to each air outlet 110b, thereby reducing cooling dead zones within the storage chamber. Furthermore, multiple air outlets 110b can reduce the airflow velocity at a single air outlet 110b, thus reducing wind noise generated at the air outlet 110b.

[0082] It is understood that other embodiments of this application do not limit the number of the first air outlet 110c and the second air outlet 110d. Exemplarily, the number of the first air outlet 110c and / or the second air outlet 110d is one.

[0083] In one embodiment, when the width of the refrigeration device in the horizontal direction is 800mm to 920mm, the distance between two adjacent first air outlets 110c in the horizontal direction is 110mm to 140mm, and the distance between two adjacent second air outlets 110d in the horizontal direction is 135mm to 160mm.

[0084] It should be noted that the spacing between adjacent first air outlets 110c and adjacent second air outlets 110d may not be equal. The spacing between the first air outlets 110c and the second air outlets 110d can be determined according to the volume and width of the corresponding storage drawer.

[0085] For example, the spacing between two adjacent air outlets 110b is related to the width of the refrigeration unit. The wider the refrigeration unit, the wider the corresponding storage drawer, thus requiring a larger spacing between the air outlets 110b to accommodate a wider storage compartment. For instance, when the width of the refrigeration unit is 890mm, the spacing between the first air outlets 110c ranges from 112mm to 122mm, and the spacing between the second air outlets 110d ranges from 135mm to 145mm. When the width of the refrigeration unit is 905mm, the spacing between the first air outlets 110c ranges from 128mm to 136mm, and the spacing between the second air outlets 110d ranges from 151mm to 160mm. The spacing between the first air outlets 110c is as follows: Figure 3As shown in the medium dimension D2, the spacing between the second air outlets 110d is as follows: Figure 3 As shown in the medium dimension D3.

[0086] In the embodiment of this application, the spacing between two adjacent air outlets 110b using the above-mentioned size can not only reduce the wind noise generated at the air outlet 110b, but also make the cooling gas in the storage room corresponding to the air outlet 110b more uniform.

[0087] It is understood that other embodiments of this application do not limit the spacing between two adjacent air outlets 110b.

[0088] In one embodiment, along the horizontal direction, the distance between two adjacent first air outlets 110c is smaller than the distance between two adjacent second air outlets 110d.

[0089] In the embodiment of this application, the distance between two adjacent first air outlets 110c is smaller than the distance between two adjacent second air outlets 110d. The airflow velocity at the second air outlet 110d is faster than the airflow velocity at the first air outlet 110c, and the larger distance at the second air outlet 110d can reduce the wind noise generated near the second air outlet 110d.

[0090] It is understood that other embodiments of this application do not limit the relationship between the distance between two adjacent first air outlets 110c and the distance between two adjacent second air outlets 110d. For example, in the horizontal direction, the distance between two adjacent first air outlets 110c is greater than or equal to the distance between two adjacent second air outlets 110d.

[0091] In one embodiment, please refer to Figure 2 The housing 100 also includes an air guide 130, which is connected to the first cover plate 110. The air guide 130 extends along the air outlet 110b toward the storage chamber. The air guide 130 has a through hole 130a, which is connected to the air outlet 110b and the storage chamber respectively.

[0092] For example, when projected along the axial direction of the through hole 130a, the projection area of ​​the through hole 130a covers the projection area of ​​the corresponding air outlet 110b.

[0093] In the embodiment of this application, the air guide 130 can guide the gas. When the storage drawer is far from the corresponding air outlet 110b, the air guide 130 can guide the cooling gas into the storage drawer, thereby reducing the diffusion of the cooling gas outside the storage room corresponding to the storage drawer.

[0094] It is understood that other embodiments of this application are not limited to whether the housing 100 is provided with an air guide 130.

[0095] In one embodiment, the diameter of the fan 300 ranges from 90 mm to 110 mm.

[0096] For example, the diameter of the fan 300 is 90mm, 95mm, 100mm, 105mm or 110mm.

[0097] Understandably, the diameter of the 300 fan can be obtained by measuring it with a ruler under normal temperature and pressure.

[0098] In the embodiment of this application, the diameter of the fan 300 is within a suitable range to ensure that there is little interference between multiple fans 300 and that the fan 300 can generate sufficient airflow to bring the cooling gas to the storage chamber.

[0099] It is understood that other embodiments of this application do not limit the diameter of the fan 300.
