Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a display cabinet. Background Technology

[0002] Refrigerated display cases are commonly used storage equipment, mainly for refrigerating beverages, beer, and dairy products. They are crucial refrigeration equipment at the end of the cold chain logistics. With rising living standards, the demand for refrigerated display cases is gradually increasing, especially regarding their capacity. Traditional refrigerated display cases place the fan and evaporator at the top of the cabinet, with air ducts reserved at the back, occupying internal space and reducing the utilization rate of top space. To address this issue, a new display case has been developed that places the fan and evaporator within the air ducts at the back of the cabinet. While this improves the utilization of top space, the vertical air ducts mean that after the airflow from the fan hits the evaporator, the cold air is directly output to the bottom of the storage cavity. Cooling then relies on the rising of the cold air, but because the cold air is heavier and rises more slowly, the storage cavity becomes colder at the bottom and warmer at the top, resulting in poor cooling performance. Utility Model Content

[0018] The beneficial effects of this utility model are:

[0019] This utility model discloses a display cabinet, which includes a cabinet body, a fan assembly, and an air duct assembly. The cabinet body has a receiving cavity for accommodating items. The fan assembly is disposed on the back panel of the receiving cavity and includes a fan with a forward-facing air inlet and a downward-facing air outlet. The air duct assembly is disposed on the back panel of the receiving cavity and extends vertically, located below the fan assembly. The air duct assembly includes an air duct, an evaporator, and an air outlet. The air duct extends vertically and has an upper opening and a lower opening. The upper opening is opposite to and communicates with the air outlet, and the lower opening is located near the middle of the receiving cavity along its height.

When the fan of the display cabinet in this embodiment is working, air is blown into the air duct through the air outlet. After the airflow is cooled by heat exchange in the evaporator, it is blown into the receiving cavity through the front air outlet and the lower air outlet. Since the lower end of the air duct is open, that is, the position of the air outlet is close to the middle position of the receiving cavity along the height direction, that is, both the front air outlet and the lower air outlet are close to the middle position of the receiving cavity along the height direction. The cold air blown out by the lower air outlet sinks down along the back panel to the bottom of the receiving cavity, and then spreads and diffuses upward in the receiving cavity. The cold air blown out by the front air outlet spreads in the middle of the receiving cavity and diffuses upward and downward. Compared with the cooling effect of related technologies where all the cold air is blown to the bottom of the receiving cavity and then spreads upward, this display cabinet can quickly cool the entire receiving cavity, thus having a better cooling effect and higher cooling efficiency.

[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0040] like Figures 1 to 11As shown, this embodiment provides a display cabinet, which includes a cabinet body 10, a fan assembly 20, and an air duct assembly 30. The cabinet body 10 has a receiving cavity 11 for storing items. The fan assembly 20 is disposed on the back plate 111 of the receiving cavity 11, and the fan assembly 20 includes a fan 21, which includes a forward-facing air inlet 211 and a downward-facing air outlet 212. The air duct assembly 30 is disposed on the back plate 111 of the receiving cavity 11 and is located below the fan assembly 20 in the vertical direction. The air duct assembly 30 includes an air duct 31 and an evaporator 32. The air outlet 33 and the air duct 31 extend in the vertical direction. The air duct 31 has an upper opening and a lower opening. The upper opening is opposite to and connected to the air outlet 212. The lower opening is located near the middle of the receiving cavity 11 in the vertical direction. The evaporator 32 is installed in the air duct 31. The air outlet 33 is connected to the lower opening of the air duct 31. The air outlet 33 is provided with a front air outlet 331 and a lower air outlet 335. The front air outlet 331 is used to blow the air in the air duct 31 forward into the receiving cavity 11. The lower air outlet 335 is used to blow the air in the air duct 31 downward into the receiving cavity 11.

[0041] In this embodiment, as Figure 3 and Figure 4 As shown, when the fan 21 is working, air enters the fan 21 through the air inlet 211, and then enters the air duct 31 through the air outlet 212. After passing through the evaporator 32, the airflow undergoes heat exchange and cooling, and is then blown into the receiving cavity 11 through the front air outlet 331 and the lower air outlet 335 respectively. Since the lower opening of the air duct 31 is close to the middle position in the height direction of the receiving cavity 11, and the air outlet 33 is connected to the lower opening of the air duct 31, it means that the front air outlet 331 and the lower air outlet 335 are both close to the middle position in the height direction of the receiving cavity 11. At the midpoint of the 10-degree direction, the cold air blown out from the lower air outlet 335 descends along the back panel 111 to the bottom of the receiving cavity 11, then spreads and diffuses upward within the receiving cavity 11. The cold air blown out from the front air outlet 331 spreads and diffuses upward and downward in the middle of the receiving cavity 11. Compared with the cooling effect of related technologies where all the cold air is blown to the bottom of the receiving cavity 11 and then spreads upward, this display cabinet can quickly cool the entire receiving cavity 11, thus having a better cooling effect and higher cooling efficiency.

[0042] Optionally, in this embodiment, as Figure 1As shown, the receiving cavity 11 also includes a top wall 115, a bottom plate 112, and two side walls 114. The top wall 115 and the bottom plate 112 are parallel and spaced apart in the vertical direction, while the two side walls 114 are parallel and spaced apart in the horizontal direction. The two ends of the two side walls 114 are respectively connected to the top wall 115 and the bottom plate 112. The top wall 115, the bottom plate 112, and the two side walls 114 are all connected to the back plate 111, forming an open receiving cavity 11. The display case also includes a cabinet door 100, which is used to seal the openness to ensure a low-temperature environment inside the receiving cavity 11, thereby ensuring the performance of the display case.

[0043] Furthermore, such as Figures 5 to 8 As shown, the front air outlet 331 includes a first front air outlet group and a second front air outlet group arranged at intervals in the left and right direction. The first front air outlet group includes a plurality of left front air outlets 332 arranged sequentially in the left and right direction. Each left front air outlet 332 is used to blow the air in the air duct 31 into the receiving cavity 11 to the left front. The second front air outlet group includes a plurality of right front air outlets 334 arranged sequentially in the left and right direction. Each right front air outlet 334 is used to blow the air in the air duct 31 into the receiving cavity 11 to the right front.

[0044] In this embodiment, the cold air blown out by the multiple left front air outlets 332 of the first front air outlet group blows towards the left front of the receiving cavity 11 from the middle position in the height direction of the receiving cavity 11, and the cold air blown out by the multiple right front air outlets 334 of the second front air outlet group blows towards the right front of the receiving cavity 11 from the middle position in the height direction of the receiving cavity 11. This allows the cold air to be distributed more widely and more evenly in the receiving cavity 11, thus resulting in a better cooling effect.

[0045] Optionally, such as Figure 4 and Figure 5 As shown, the air outlet 33 includes a vertical plate 338, which is parallel to the back plate 111 and spaced apart in the front-rear direction. Multiple left front air outlets 332 and multiple right front air outlets 334 are all opened on the vertical plate 338.

[0046] Optionally, such as Figure 7 As shown, the number of left front air outlets 332 is the same as the number of right front air outlets 334, and the multiple left front air outlets 332 and the multiple right front air outlets 334 are symmetrically arranged about the middle position of the receiving cavity 11 in the left-right direction.

[0047] Optionally, the number of left front air vents 332 and the number of right front air vents 334 can be different, and the number and location of multiple left front air vents 332 and multiple right front air vents 334 can be specifically set according to actual use, without specific restrictions here.

[0048] Optionally, such as Figure 5As shown, the upright plate 338 is provided with multiple through holes 348, and multiple fasteners pass through the multiple through holes 348 one by one and are fastened to the back plate 111 to ensure the stability of the installation of the upright plate 338.

[0049] Furthermore, such as Figure 5 and Figure 7 As shown, the air outlet component 33 also includes a first air guide plate 336 and a second air guide plate 337 connected in a V-shape. The first air guide plate 336 is used to guide the airflow in the air duct 31 to the first front air outlet group, and the second air guide plate 337 is used to guide the airflow in the air duct 31 to the second front air outlet group.

[0050] In this embodiment, the first air guide plate 336 and the second air guide plate 337 form a V-shaped structure, and the opening of the V-shaped structure is away from the lower opening of the air duct 31. This allows the air output from the lower opening to be guided by the first air guide plate 336 and the second air guide plate 337 to the first front air outlet group and the second front air outlet group, respectively. This further diverts the cold air output from the lower opening of the air duct 31 to the left and right sides, thereby making the cold air more evenly distributed in the receiving cavity 11 and further improving the cooling effect of the display cabinet.

[0051] Optionally, such as Figure 7 As shown, the connecting tips of the first guide plate and the second guide plate are opposite to the center position of the receiving cavity 11 in the left-right direction, which can ensure that the flow rate of cold air guided to the first front air outlet group and the second front air outlet group is approximately the same, thereby improving the temperature uniformity in the receiving cavity 11.

[0052] Optionally, such as Figure 5 and Figure 7 As shown, the first air guide plate 336 and the second air guide plate 337 are both arranged perpendicular to the vertical plate 338. The two sets of front air outlets 331 opened on the vertical plate 338 are symmetrically arranged about the connecting tips of the first guide plate and the second guide plate, thereby improving the temperature uniformity in the accommodating cavity 11.

[0053] Furthermore, such as Figure 6 As shown, the front air outlet 331 also includes a third front air outlet group, which includes multiple obliquely upward front air outlets 333 arranged sequentially in the left-right direction. Each obliquely upward front air outlet 333 is used to blow the air in the air duct 31 into the receiving cavity 11 obliquely upward.

[0054] In this embodiment, multiple upward-facing air outlets 333 direct the airflow in the air duct 31 into the receiving cavity 11 at an upward angle, which is more conducive to the upward diffusion of cold air and results in a better cooling effect.

[0055] Optionally, such as Figure 7As shown, the upright plate 338 has multiple left front air outlets 332, multiple right front air outlets 334, and multiple oblique front air outlets 333. The multiple left front air outlets 332 and multiple right front air outlets 334 are arranged in a row along the left and right directions, and the multiple oblique front air outlets 333 are arranged in a row along the left and right directions. The oblique front air outlets 333 are located below the multiple left front air outlets 332 and multiple right front air outlets 334. The arrangement width of the multiple oblique front air outlets 212, and the total arrangement width of the multiple left front air outlets 332 and multiple right front air outlets 334, match the width of the receiving cavity 11 along the left and right directions, thereby ensuring the air volume of cold air and improving the cooling efficiency of the display cabinet.

[0056] Furthermore, such as Figure 3 and Figure 4 As shown, a gap 116 is formed between the air outlet 33 and the back panel 111, and the gap 116 is used to drain the condensate in the air duct 31.

[0057] In this embodiment, after the air passes through the evaporator 32 for heat exchange and cooling, condensation will be generated on the back plate 111 during the flow of air in the air duct 31. The condensation will flow out of the air duct 31 through the gap 116 formed between the air outlet 33 and the back plate 111, and continue to flow down along the back plate 111 until it flows to the bottom plate 112 of the receiving cavity 11. This avoids the condensation from accumulating in the air duct 31 and affecting the air flow, thus ensuring the cooling effect and cooling efficiency of the display cabinet.

[0058] Optionally, the bottom plate 112 of the receiving cavity 11 is provided with a drain outlet 113 that communicates with the outside. After the condensate flows to the bottom plate 112, it is discharged from the drain outlet 113, thereby preventing the condensate from affecting the normal use of the display cabinet.

[0059] Furthermore, such as Figure 5 and Figure 6As shown, the air outlet component 33 includes a vertical plate 338, a first horizontal plate 339, a second horizontal plate 340, and two side plates 341. The vertical plate 338 and the back plate 111 are opposite to each other in the front-to-back direction and spaced apart. The two side plates 341 are opposite to each other in the left-to-right direction and spaced apart, and both side plates 341 are connected to the vertical plate 338 at an angle. The first horizontal plate 339 and the second horizontal plate 340 are parallel and spaced apart, and both the first horizontal plate 339 and the second horizontal plate 340 are connected between the two side plates 341. The first horizontal plate 339 is connected to the vertical plate 338 at an angle. The second horizontal plate 340 is spaced apart from the back panel 111, and the vertical plate 338 is spaced apart from the second horizontal plate 340. The front air outlet 331 is opened on the vertical plate 338. The front air outlet 331 includes multiple left front air outlets 332, multiple right front air outlets 334, and multiple oblique upper front air outlets 333. The multiple left front air outlets 332 and multiple right front air outlets 334 are all located above the first horizontal plate 339, and the multiple oblique upper front air outlets 333 are all located below the first horizontal plate 339. The lower air outlet 335 is formed between the second horizontal plate 340 and the vertical plate 338.

[0060] In this embodiment, as Figure 5 As shown, the air outlet component 33 includes a vertical plate 338, a first horizontal plate 339, a second horizontal plate 340, and two side plates 341. Both side plates 341 are connected to the vertical plate 338 at an angle. The first horizontal plate 339 and the second horizontal plate 340 are connected between the two side plates 341, thereby improving the structural strength of the air outlet component 33 and ensuring the air outlet performance and air outlet effect of the air outlet component 33.

[0061] Optionally, the second horizontal plate 340 is spaced apart from the back plate 111, forming a gap 116 between them for condensate to flow down from the back plate 111.

[0062] Optionally, the air outlet component 33 is formed by plastic injection molding, which is convenient to process and low in cost.

[0063] Furthermore, such as Figures 9 to 11 As shown, the air duct assembly 30 also includes an air duct plate 342, a left frame 343, a right frame 344, and two sealing blocks 345. The air duct plate 342 and the back plate 111 are arranged opposite to each other in the front-back direction and spaced apart. The left frame 343 and the right frame 344 are arranged opposite to each other in the left-right direction and spaced apart. The left frame 343 and the right frame 344 are both connected between the back plate 111 and the air duct plate 342. The evaporator 32 is located between the left frame 343 and the right frame 344, and a first gap 346 is formed between the evaporator 32 and the left frame 343. A second gap 347 is formed between the evaporator 32 and the right frame 344. The two sealing blocks 345 respectively seal the first gap 346 and the second gap 347, and both sealing blocks 345 are located at the end of the evaporator 32 near the fan assembly 20.

[0064] In this embodiment, two sealing blocks 345 are respectively embedded in the first gap 346 formed between the evaporator 32 and the left frame 343 and the second gap 347 formed between the evaporator 32 and the right frame 344, so that all the air blown out of the air outlet 212 of the fan 21 passes through the evaporator 32 for cooling and heat exchange, thereby improving the cooling efficiency.

[0065] Optionally, the sealing block 345 is a sealing sponge.

[0066] Optionally, the left frame 343, the right frame 344, and the air outlet 33 are all connected to the back plate 111, and the evaporator 32 is fixedly connected to the back plate 111 to improve the installation stability of the evaporator 32.

[0067] Furthermore, the air duct plate 342 is made of a light-transmitting material, and the air duct assembly 30 also includes a light strip, the light emitted by which can pass through the air duct plate 342 and enter the receiving cavity 11.

[0068] In this embodiment, the air duct assembly 30 also includes a support frame and a rear reflector. The support frame can be assembled from four aluminum profiles and is rectangular in shape. The air duct plate 342 and the rear reflector are both embedded in the support frame and are arranged in parallel and spaced apart. The air duct plate 342 can be made of materials such as translucent frosted plastic or glass and can diffuse light. The light strip is arranged inside the support frame and between the air duct plate 342 and the rear reflector. The light generated by the light strip will be reflected multiple times between the rear reflector and the air duct plate 342, so that the light becomes uniform and shines forward through the air duct plate 342, making the air duct plate 342 emit soft and uniform light, which is conducive to clear observation of the receiving cavity 11 and improves the user experience.

[0069] Furthermore, such as Figure 11 As shown, the fan assembly 20 includes two fans 21, both of which are fixedly connected to the back plate 111. The two fans 21 are arranged at intervals in the left-right direction. The air outlets 212 of the two fans 21 face downwards and cover the entire evaporator 32 in the left-right direction.

[0070] In this embodiment, the air outlets 212 of the two fans 21 cover the entire evaporator 32, thereby maximizing the flow of air blown out by the two fans 21 through the evaporator 32, thus ensuring the heat exchange efficiency of the evaporator 32 and improving the cooling efficiency of the display cabinet.

[0071] Alternatively, in another embodiment, the number of fans 21 can be specifically set according to actual use, as long as it is ensured that the air outlets 212 of all fans 21 cover the entire evaporator 32.

The first plate 221 and the third plate 223 are both connected to the back plate 111. The second plate 222 is provided with two openings 224, and the air inlets 211 of the two fans 21 are correspondingly opposite to the two openings 224.

[0073] In this embodiment, the U-shaped connection of the first plate 221, the second plate 222, and the third plate 223 enhances the structural strength of the cover plate 22, and forms a receiving space to accommodate the fan 21, thereby ensuring sufficient installation space for the fan 21. Additionally, the second plate 222 has two openings 224 corresponding one-to-one with the air inlets 211 of the two fans 21, ensuring normal air intake for both fans 21 and guaranteeing their normal operation.

[0074] Alternatively, in another embodiment, the number of openings 224 corresponds to the number of fans 21, and each fan 21 is provided with an opening 224, thereby ensuring that all fans 21 can take in air normally.
