[0039] The present application provides a refrigeration device, which may be a refrigerator or a freezer.

[0040] Please refer to Figure 1 and Figure 2 , Figure 1 This is a structural diagram of a refrigeration device according to an embodiment of the present utility model. Figure 2 This is a schematic diagram of the interior structure of a compressor compartment according to the first embodiment of the present invention. Refrigeration equipment 10 includes a housing 100, a centrifugal fan 200, a condenser 300, and a bracket 400. The housing 100 is provided with a compressor compartment 101. The centrifugal fan 200, condenser 300, and bracket 400 are all located within the compressor compartment 101.

[0041] The centrifugal fan 200 comprises a rotor 230, a volute 210, and an outlet housing 220 connected to the volute 210. The volute 210 is provided with an air cavity, within which the rotor 230 is rotatably mounted. Specifically, the centrifugal fan 200 has axial air intake and radial air discharge. During operation, the centrifugal fan 200 generates negative pressure within the air cavity, drawing outside air into the air cavity from its axial air inlet. Driven by the rotor 230, the air then rotates centrifugally along the inner wall of the volute 210 and is discharged radially from the outlet housing 220.

[0042] By using centrifugal fan 200, centrifugal fan 200 has higher pressure resistance than axial flow fans. Under the same environment, centrifugal fan 200 has less air volume attenuation under high static pressure and can produce a higher air volume than axial flow fans. In particular, when refrigeration device 10 is a built-in refrigerator, the compressor compartment 101 is close to a wall or cabinet, and the air inlet and outlet resistance of the compressor compartment 101 is relatively large. Centrifugal fan 200 has a greater advantage in overcoming this air inlet and outlet resistance, providing a larger air volume, effectively blowing heat from the condenser 300 out of the compressor compartment 101, and thus improving the heat dissipation capacity of the built-in refrigerator.

[0043] The bracket 400 is used to support the centrifugal fan 200 and / or the condenser 300. Figure 2 And refer to Figure 3 , Figure 3 This is a schematic diagram illustrating the assembly of a bracket, condenser, and centrifugal fan according to an embodiment of the present invention. The bracket 400 includes a partition plate 410. The partition plate 410 and the inner wall of the compressor compartment 101 define a first accommodating chamber 1011. The condenser 300 and volute 210 are located within the first accommodating chamber 1011. The air outlet housing 220 extends through the partition plate 410, with at least a portion of the air outlet housing 220 located outside the first accommodating chamber 1011.

[0044] In this embodiment, the condenser 300 and the volute 210 of the centrifugal fan 200 are disposed within the first accommodating chamber 1011, and at least a portion of the air outlet housing 220 is disposed outside the first accommodating chamber 1011. The centrifugal fan 200 can draw outside air into the first accommodating chamber 1011 to exchange heat with the condenser 300, and then discharge the hot air after heat exchange to the outside of the first accommodating chamber 1011 through the air outlet housing 220. Due to the provision of the partition plate 410, the partition plate 410 can block the hot air discharged from the air outlet housing 220 outside the first accommodating chamber 1011, so that the hot air is located in the space on the side of the partition plate 410 facing away from the first accommodating chamber 1011. This can prevent the hot air from flowing back into the condenser 300, thereby preventing the formation of cross-flow wind that affects the heat dissipation of the condenser 300.

[0045] In some embodiments, please refer to Figure 2 and Figure 3 The centrifugal fan 200 and the condenser 300 are arranged along the first direction, the thickness direction of the condenser 300 is parallel to the first direction, and the rotation axis direction of the centrifugal fan 200 is parallel to the first direction. Figure 2 In other words, this embodiment arranges the centrifugal fan 200 and condenser 300 vertically, unlike conventional refrigerators where the fan and condenser are arranged horizontally and side to side. Furthermore, the thickness of the condenser 300 in this embodiment is parallel to the vertical direction, meaning the condenser 300 is arranged horizontally, unlike conventional refrigerators where the condenser is arranged vertically. Furthermore, the rotation axis of the centrifugal fan 200 in this embodiment is also arranged vertically, achieving vertical air intake, unlike conventional refrigerators where the fan adopts horizontal air intake.

[0046] Generally speaking, for a conventionally shaped condenser 300, the maximum dimension of the condenser 300 is the length or width of the condenser 300, and the dimension in the thickness direction is usually the smallest. Similarly, for a conventional centrifugal fan 200, the maximum dimension of the centrifugal fan 200 is usually its radial dimension, and the axial dimension of the centrifugal fan 200 is the smallest. In this embodiment, the condenser 300 and the centrifugal fan 200 are arranged vertically along the height direction of the box body 100, that is, the condenser 300 is arranged horizontally so that the thickness direction of the condenser 300 is parallel to the height direction of the box body 100. The rotation axis direction of the centrifugal fan 200 is also set along the height direction of the box body 100. Since the thickness dimension of the condenser 300 and the axial dimension of the centrifugal fan 200 are both small, after the condenser 300 and the centrifugal fan 200 are arranged in the vertical direction in this embodiment, the height occupied by the two is still smaller than the height occupied by the vertical arrangement of the condenser in the traditional refrigerator. Therefore, compared with the traditional refrigerator, the space occupied in the height direction of the compressor compartment 101 can be reduced, the height of the compressor compartment 101 can be lowered, and the volume of the compressor compartment 101 can be reduced, so that the storage space of the refrigeration equipment 10 can be effectively increased without increasing the overall volume of the refrigeration equipment 10.

[0047] Moreover, the condenser 300 and the centrifugal fan 200 are arranged up and down. This arrangement conforms to the air inlet and outlet characteristics of the centrifugal fan 200, that is, axial air intake and radial air outlet, and can bring into play the maximum efficiency of the centrifugal fan 200.

[0048] It should also be pointed out that in traditional refrigerators using axial flow fans in the relevant technology, the axial flow fans are usually arranged vertically, that is, the rotation axis of the axial flow fan is set in the horizontal direction, so the overall center of gravity of the axial flow fan is relatively high. The axial flow fan is prone to shaking during high-speed operation, generating vibration noise, and the vibration of the axial flow fan is likely to cause other components in the compressor compartment to resonate and enhance the vibration noise. The superposition of these noises causes the noise intensity generated by the refrigerator to be relatively high, affecting the user experience.

[0049] In this embodiment, the rotation axis of the centrifugal fan 200 is arranged along the height direction of the box body 100, that is, the centrifugal fan 200 is arranged horizontally, so that the center of gravity of the centrifugal fan 200 is at a lower position. Then, the centrifugal fan 200 is installed more firmly in the compressor compartment 101, and the centrifugal fan 200 is not easy to shake during high-speed operation. The vibration amplitude of the centrifugal fan 200 can be reduced, thereby reducing the vibration noise of the centrifugal fan 200 itself, and at the same time reducing the vibration noise generated by the resonance of other components in the compressor compartment 101 caused by the vibration of the centrifugal fan 200, which can effectively reduce the noise intensity of the refrigeration equipment 10 and improve the user experience.

[0050] In some embodiments, please refer to Figure 2The compressor compartment 101 includes a base plate 110 , a centrifugal fan 200 is mounted on the base plate 110 , a bracket 400 is mounted on the centrifugal fan 200 , and the condenser 300 is supported by the bracket 400 on a side of the centrifugal fan 200 away from the base plate 110 .

[0051] That is, the centrifugal fan 200 is located on the lower side of the condenser 300. The centrifugal fan 200 can be installed on the bottom plate 110 instead of being suspended on the upper side of the condenser 300. The bottom plate 110 can well bear the weight and working load of the centrifugal fan 200, ensuring the stability of the installation of the centrifugal fan 200. At the same time, it is beneficial to the stability of the operation of the centrifugal fan 200 and can reduce the vibration and noise generated during the operation of the centrifugal fan 200. Moreover, for a built-in refrigerator, since the cabinet 100 is close to the wall or cabinet, the exhaust port of the compressor compartment 101 is generally set on the bottom plate 110, and the air is exhausted through the gap between the bottom of the cabinet 100 and the ground. In this embodiment, the centrifugal fan 200 is installed on the bottom plate 110, so that the air outlet side of the centrifugal fan 200 is closer to the exhaust port of the compressor compartment 101, which is beneficial for exhausting hot air from the compressor compartment 101 to the outside of the cabinet 100.

[0052] Combine Figure 2 and Figure 3 As shown, the condenser 300 is located on the air inlet side of the centrifugal fan 200, that is, the air inlet of the centrifugal fan 200 faces the condenser 300. When the centrifugal fan 200 is in operation, the air entering the first accommodating chamber 1011 from the outside first flows through the condenser 300 before being drawn into the centrifugal fan 200 for acceleration. When the air flows through the condenser 300, the air flow rate is relatively slow and the flow field is uniform, so that the condenser 300 can fully exchange heat with the flowing air, thereby improving the heat exchange efficiency. Moreover, the outside air is drawn into the condenser 300 under the action of negative pressure. Compared with being blown toward the condenser 300 through the centrifugal fan 200, the noise generated by the air flowing through the condenser 300 will be smaller, which is beneficial to the noise control of the refrigeration equipment 10.

[0053] In some embodiments, the bracket 400 further includes a plurality of panels 420 connected to the side of the partition plate 410 facing the first accommodating chamber 1011. The plurality of panels 420 and the partition plate 410 enclose an air guide chamber 400a. The air guide chamber 400a is connected to the air inlet of the centrifugal fan 200, and the condenser 300 is installed in the air guide chamber 400a. With this configuration, the bracket 400 is generally cylindrical in shape. By designing the bracket 400 with this structural shape, the direction of air flow can be defined. The bracket 400 can guide air flow through the air guide chamber 400a, preventing air from entering the first accommodating chamber 1011 from scattering, thereby reducing airflow noise and improving heat dissipation efficiency.

[0054] Among them, the air guide cavity 400a can be sealed and connected with the air inlet of the centrifugal fan 200. Specifically, the bottom end of each enclosure 420 can be connected to the centrifugal fan 200, and the bottom plate 110 of the partition plate 410 is connected to the centrifugal fan 200, so that there is no gap between the air guide cavity 400a and the air inlet of the centrifugal fan 200. Therefore, during the operation of the centrifugal fan 200, the air sucked into the first accommodating cavity 1011 must first enter the air guide cavity 400a before passing through the air inlet of the centrifugal fan 200, that is, the air must first flow through the condenser 300 to exchange heat with it before entering the inside of the centrifugal fan 200, preventing the air entering the first accommodating cavity 1011 from being sucked into the centrifugal fan 200 before exchanging heat with the condenser 300, thereby making full use of the air for heat dissipation and improving the heat dissipation efficiency.

[0055] For built-in refrigerators, since the sides and back of the cabinet 100 are close to the wall or cabinet, the gap between the cabinet 100 and the wall or cabinet is very small. To better dissipate heat, air can be introduced and exhausted through the gap between the bottom of the cabinet 100 and the ground. In some embodiments, please refer to Figure 4 and Figure 5 , Figure 4 This is a schematic structural diagram of the interior of the compressor compartment of the first embodiment of the present invention from a second perspective. Figure 5 The bottom plate 110 is provided with a first air inlet 110a and an air outlet 110b, and the first air inlet 110a and the air outlet 110b are arranged along the second direction, which is parallel to the width direction of the box body 100. Figure 5 The first air inlet 110a is connected to the first accommodating chamber 1011 , and the air outlet 110b is connected to the space on the side of the partition plate 410 away from the first accommodating chamber 1011 .

[0056] In order to avoid the mutual influence between the bottom air intake and the bottom air exhaust, and to prevent the hot air exhausted from the exhaust port 110b from being sucked back into the first accommodating chamber 1011 through the first air intake port 110a, a partition bar 130 may be provided at the bottom of the box body 100. Figure 5 As shown, the dividing strip 130 is connected to the bottom plate 110, and the dividing strip 130 extends along the depth direction of the box body 100. The dividing strip 130 divides the space between the bottom of the box body 100 and the ground into left and right side spaces, so that the relatively low temperature cold air from the outside flows along one side space and enters the first accommodating cavity 1011 through the first air inlet 110a. The hot air in the compressor compartment 101 is discharged to the other side space through the exhaust port 110b and flows out along this side space.

[0057] The compressor compartment 101 further includes a plurality of side panels 120. To improve the air intake efficiency, air inlets may also be provided on the side panels 120 of the compressor compartment 101. Figure 6, Figure 6 This is a schematic diagram of the structure of the exterior of a compressor compartment according to an embodiment of the present invention. The compressor compartment 101 includes a first side panel 121, a second side panel 122, and a third side panel 123 connected to the bottom panel 110. The first side panel 121 and the second side panel 122 are connected to adjacent sides of the bottom panel 110. The first side panel 121 is located on the rear side (i.e., the back) of the compressor compartment 101, the second side panel 122 is located on the left or right side (i.e., the side) of the compressor compartment 101, and the third side panel 123 is spaced apart from and arranged opposite to the first side panel 121. In some embodiments, the first side panel 121 and / or the second side panel 122 may be provided with a second air inlet 120a, which is connected to the first accommodating chamber 1011.

[0058] For example, see Figure 7 , Figure 7 This is a schematic diagram of an air intake for a compressor compartment according to an embodiment of the present invention. The first side panel 121 is provided with a second air inlet 120a. The compressor compartment 101 can take in air through the first air inlet 110a at the bottom and the second air inlet 120a at the back, that is, it includes two air intake paths: bottom air intake and back air intake. Alternatively, in other embodiments, the second side panel 122 is provided with a second air inlet 120a. The compressor compartment 101 takes in air through the first air inlet 110a at the bottom and the second air inlet 120a at the side, that is, it includes two air intake paths: bottom air intake and side air intake. Alternatively, in yet other embodiments, both the first side panel 121 and the second side panel 122 are provided with a second air inlet 120a. The compressor compartment 101 can take in air through the first air inlet 110a and the two second air inlets 120a, that is, it includes three air intake paths: bottom air intake, back air intake and side air intake. It is understandable that the specific configuration of the first air inlet 110a can be determined according to the heat dissipation requirements of the refrigeration device 10. The drawings of this embodiment only take the first case as an example and cannot be regarded as a limitation to this application.

[0059] By setting a second air inlet 120a on the first side panel 121 and / or the second side panel 122, the air inlet path of the compressor compartment 101 is increased, the air inlet area is increased, the air intake volume and air intake efficiency can be improved, and to a certain extent, the problem of poor air intake of the built-in refrigerator due to being close to the wall or cabinet can be improved, and the heat dissipation efficiency can be improved.

[0060] To facilitate air intake, each enclosure 420 of the bracket 400 is spaced apart from each side panel 120 of the compressor compartment 101. In some embodiments, the minimum spacing between each enclosure 420 and the side panel 120 opposite thereto is greater than or equal to 20 mm.

[0061] Combined with reference Figure 4 and Figure 7As shown, the bracket 400 includes a first enclosing plate 421, a second enclosing plate 422, and a third enclosing plate 423 connected in sequence. Taking the first enclosing plate 421 and the third enclosing plate 423 as an example, the first enclosing plate 421 is disposed opposite the first side plate 121, and the third enclosing plate 423 is disposed opposite the third side plate 123. The minimum spacing between the first enclosing plate 421 and the first side plate 121 is defined as L1, L1 ≥ 20 mm, and the minimum spacing between the third enclosing plate 423 and the third side plate 123 is defined as L3, L3 ≥ 20 mm.

[0062] In the circumferential direction of the bracket 400, except for the partition plate 410, a large ventilation gap is formed between the bracket 400 and each side plate 120 of the compressor compartment 101, which can reduce the wind intake resistance and facilitate the outside air to enter the first accommodating cavity 1011. At the same time, the larger ventilation gap is conducive to air flow, so that the air entering the first accommodating cavity 1011 can be quickly sucked into the air guide cavity 400a, thereby improving the heat dissipation effect of the condenser 300.

[0063] In some embodiments, the air outlet housing 220 is provided with an air outlet duct 220a. The height of the air outlet duct 220a along the first direction is greater than or equal to 30 mm, that is, the height of the air outlet duct 220a along the height direction of the housing 100 is greater than or equal to 30 mm. Thus, in this embodiment, the air outlet duct 220a is configured to be higher in height, providing a larger air volume, allowing the centrifugal fan 200 to discharge hot air in a timely manner, thereby preventing heat from being retained in the compressor compartment 101.

[0064] In some embodiments, please refer to Figure 8 , Figure 8 This is a schematic diagram of the structure inside the compressor compartment of the second embodiment of the present invention. The refrigeration device 10 includes a heat shield 500 and a compressor 600, both of which are disposed within the compressor compartment 101. The heat shield 500 is located between the compressor 600 and the partition 410 of the bracket 400. As will be readily understood, the heat shield 500 acts as a thermal insulator, preventing heat from the compressor 600 from being transferred toward the bracket 400 and condenser 300, thereby preventing heat from being transferred into the first accommodating chamber 1011 and preventing the heat generated by the compressor 600 from affecting the heat dissipation of the condenser 300.

[0065] The heat insulation board 500 is made of a material with good heat insulation properties, for example, the heat insulation board 500 can be a foam board.

[0066] Please continue to refer to Figure 8The heat shield 500 may be provided with a through hole 500a extending through its thickness, with the end of the air outlet housing 220 away from the volute 210 being provided with a through hole 500a. The hot air blown out from the air outlet housing 220 is then discharged directly into the space on the side of the heat shield 500 that faces away from the bracket 400. The heat shield 500 also prevents heat carried by the hot air from being transferred to the partition plate 410 through the air, further preventing heat from flowing back to the condenser 300, thereby facilitating heat dissipation within the condenser 300.

[0067] The refrigeration device 10 further includes a water receiving pan 700, which is disposed in the compressor compartment 101 and is used to receive and hold the defrost water or condensed water flowing out of the storage compartment of the refrigeration device 10. Figure 2 The compressor 600 , the water receiving pan 700 and the condenser 300 are arranged in sequence along the second direction, ie, the width direction of the cabinet 100 , and the water receiving pan 700 is provided between the compressor 600 and the condenser 300 .

[0068] In this embodiment, the compressor 600, the water collecting pan 700 and the condenser 300 are arranged along the width direction of the housing 100, and the water collecting pan 700 is located on the side of the condenser 300. This effectively utilizes the space vacated on the side of the condenser 300 after the condenser 300 and the centrifugal fan 200 are arranged vertically up and down, thereby improving the utilization rate of the space in the compressor compartment 101. At the same time, compared with the traditional refrigerator in which the water collecting pan 700 is set at the bottom of the condenser 300, the space occupied in the height direction of the compressor compartment 101 is reduced, the height dimension of the compressor compartment 101 can be reduced, thereby further reducing the volume of the compressor compartment 101, and effectively increasing the storage space capacity of the refrigeration equipment 10.

[0069] In some embodiments, please refer to Figure 2 The air outlet shell 220 includes a first air outlet portion 221, which is located in the space on the side of the partition plate 410 away from the first accommodating chamber 1011. The first air outlet portion 221 is the portion of the air outlet shell 220 extending outside the first accommodating chamber 1011, and the water receiving tray 700 is installed on the top of the first air outlet portion 221.

[0070] By installing the water receiving tray 700 on the top of the first air outlet part 221, that is, the water receiving tray 700 and the air outlet shell 220 are arranged vertically up and down, the water receiving tray 700 utilizes the space above the air outlet shell 220 and does not occupy the lower space. Then the air outlet shell 220 can make full use of the lower space for configuration, making the air outlet shell 220 set wider, increasing the width of the air outlet channel 220a, and improving the air outlet efficiency, which is beneficial to the discharge of hot air.

[0071] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
