Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, specifically providing a protective cover and refrigeration equipment. Background Technology

[0002] Existing refrigeration equipment on the market, taking refrigerators as an example, primarily uses rear-exhaust cooling. This technology achieves cooling by first cooling the rear section and then transferring the cooling to the front. In these refrigerators, the fan and evaporator are located at the rear of the cabinet, while the duct cover is at the front, primarily for decoration and protection of the fan and evaporator. However, placing the fan and evaporator at the rear increases the overall width of the cabinet, reducing usable space. Furthermore, the duct cover creates an airflow channel between itself and the rear of the cabinet, which is detrimental to airflow guidance. Summary of the Invention

[0003] This application aims to solve the aforementioned technical problem, namely, to address the issue that the duct cover plate installed at the rear of the refrigeration equipment in the prior art is difficult to guide the air in the duct.

[0004] This application provides a protective cover for accommodating an evaporator and a fan in a refrigeration device. The protective cover includes: a side plate; and a shaped plate including a front plate, a bottom plate, and a connecting plate. The front plate and the bottom plate are connected through the connecting plate. The side plate is connected to one end of the shaped plate to form a receiving groove between the side plate and the shaped plate. The connecting plate is recessed in the direction of the receiving groove. The receiving groove is used to accommodate the fan and the evaporator.

[0005] In the optional technical solutions of the above-mentioned protective cover, a water-blocking bracket is also included. The water-blocking bracket includes a first part and a second part. The first part is connected to the connecting plate, and the second part is disposed on the first part and extends upward from the first part. Both the first part and the second part abut against the side plate. A first receiving groove is formed between the second part, the connecting plate and the front plate. The first receiving groove is used to receive the evaporator. A second receiving groove is formed between the bottom plate, the connecting plate and the second part. The second receiving groove is used to receive the fan.

[0006] In the optional technical solutions of the above-mentioned protective cover, a drainage part is also included. The drainage part abuts against the connecting plate and forms a drainage groove between the connecting plate and the connecting plate. The drainage groove communicates with the first receiving groove and is located at the bottom of the first receiving groove. A drainage outlet is provided at the bottom of the drainage part.

[0007] In the optional technical solution of the above protective cover, the connecting plate is configured as an arc panel recessed towards the receiving groove, and the arc panel located at the bottom of the first receiving groove is inclined from the front plate towards the first part.

[0008] In the optional technical solution of the above protective cover, the drainage part is located at the end of the connecting plate away from the side plate.

[0009] In the optional technical solutions of the above-mentioned protective cover, a flow guide is also included. The flow guide is provided with a relief groove. The flow guide is located at the bottom of the base plate, and the relief groove is connected to the second receiving groove so that the fan can be extended into the relief groove.

[0010] In the optional technical solution of the above protective cover, the air guide includes a side baffle and an air guide plate. The side baffle and the air guide plate together enclose the avoidance groove, and the air guide plate is configured to be recessed in the direction of the avoidance groove.

[0011] In the optional technical solution of the above protective cover, the front plate is provided with an air inlet, which connects the receiving groove to the outside of the receiving groove.

[0012] This application also provides a refrigeration device, including: a protective cover as described in any of the above technical solutions; a fan; an evaporator; a housing, wherein a refrigeration chamber is provided inside the housing, a top air duct is formed between the protective cover and the inner top wall of the refrigeration chamber, the fan and the evaporator are disposed in the top air duct, and a side air duct communicating with the top air duct is also provided inside the refrigeration chamber.

[0013] In the optional technical solutions of the above-mentioned refrigeration equipment, the front panel is provided with an air inlet, the evaporator is arranged close to the air inlet, and the evaporator is located between the fan and the air inlet.

[0014] When the above technical solution is adopted, the protective cover of this application can protect the fan and evaporator, and the recessed connecting plate in the direction of the receiving groove can also gather the air in the top air duct and guide it to the side air duct, thereby further ensuring that the cooled air can be efficiently introduced into the side air duct.

[0027] Combination Figure 1 and Figure 2 This application also provides a refrigeration device 1, which includes a protective cover 12, a fan 13, an evaporator 14, and a housing 10. A refrigeration chamber 11 is provided inside the housing 10. A top air duct 113 is formed between the protective cover 12 and the inner top wall 111 of the refrigeration chamber 11. The fan 13 and evaporator 14 are disposed within the top air duct 113. A side air duct 112 communicating with the top air duct 113 is also provided inside the refrigeration chamber 11. By placing the fan 13 and evaporator 14 within the top air duct 113 of the refrigeration chamber 11, the space occupied by the fan 13 and evaporator 14 in the depth direction of the refrigeration chamber 11 is reduced compared to placing them on the rear side of the refrigeration chamber 11. This ensures that more items can be accommodated within the refrigeration chamber 11 without changing the volume of the housing 10.

[0028] In addition, the fan 13 and the evaporator 14 are provided with a protective cover 12 to prevent external impurities from entering the top air duct 113 and affecting the operation of the fan 13 and the evaporator 14. At the same time, the protective cover 12 can also guide the airflow, so as to ensure that the top air duct 113 and the side air duct 112 can better deliver the cooling air to the cooling chamber 11, and also prevent the liquid on the surface of the evaporator 14 from being unable to drain and accumulating on the surface of the evaporator 14, causing the evaporator 14 to freeze.

[0029] To more clearly describe the function of the protective cover 12 for the fan 13 and the evaporator 14, the protective cover 12 will be described in detail below.

[0030] Combination Figures 3 to 5This application provides a protective cover 12 that can accommodate an evaporator 14 and a fan 13 within a refrigeration device 1. The protective cover 12 includes a side plate 124 and a shaped plate 120. The shaped plate 120 includes a front plate 121, a bottom plate 122, and a connecting plate 123. The front plate 121 and the bottom plate 122 are connected by the connecting plate 123. The side plate 124 is connected to one end of the shaped plate 120 to form a receiving groove 127 between the side plate 124 and the shaped plate 120. The fan 13 and the evaporator 14 are located within the receiving groove 127. The shaped plate 120 and the side plate 124 together surround the evaporator 14 and the fan 13, thereby protecting the evaporator 14 and the fan 13. The connecting plate 123 is recessed towards the receiving groove 127. When the protective cover 12 is installed within the refrigeration chamber 11, it combines with... Figure 1 and Figure 3 The connecting plate 123, which is recessed towards the receiving groove 127, can avoid items inside the cooling chamber 11, thereby increasing the space for other items in the cooling chamber 11 to a certain extent. In addition, the bottom of the protective cover 12 is connected to the air duct side plate 1122 of the side air duct 112. Since the connecting plate 123 is recessed towards the receiving groove 127, the width of the top air duct 113 gradually decreases from away from the side air duct 112 to closer to the side air duct 112. Therefore, the connecting plate 123, which is recessed towards the receiving groove 127, can gather the air in the top air duct 113 and guide it to the side air duct 112, thereby further reducing the proportion of cooled air that cannot flow from the air outlet 1121 to the cooling chamber 11. Since the evaporator 14 is located inside the receiving tank 127, when the evaporator 14 is above the connecting plate 123, and the connecting plate 123 is recessed towards the receiving tank 127, the connecting plate 123 can also guide water dripping from the evaporator 14 into the receiving tank 127 downwards along the recessed direction of the connecting plate 123, preventing water from accumulating and affecting the operation of the evaporator 14. Therefore, the connecting plate 123 can also serve as a guide. Thus, the protective cover 12 can protect the fan 13 and the evaporator 14 while also serving as a guide for airflow.

[0031] In one embodiment, combined with Figures 1 to 6The front panel 121 is provided with an air inlet 1211, which connects the receiving slot 127 to the outside of the receiving slot 127. When the protective cover 12 is installed inside the refrigeration chamber 11 and forms a top air duct 113 with the inner top wall 111 of the refrigeration chamber 11, the receiving slot 127 is located inside the top air duct 113. The top air duct 113 is connected to the storage space of the refrigeration chamber 11 through the air inlet 1211 of the front panel 121. The air in the refrigeration chamber 11 enters the top air duct 113 through the air inlet 1211. The air in the top air duct 113 flows under the action of the fan 13 and returns to the refrigeration chamber 11 from the air outlet 1121 of the side air duct 112, thereby forming a refrigeration cycle to cool the items in the refrigeration chamber 11. The front panel 121 faces the refrigeration chamber 11, and the air inlet 1211 is located on the front panel 121 to ensure a sufficiently large return air area, thereby improving the return air efficiency.

[0032] In one embodiment, reference is made to... Figure 3 When the front panel 121 is provided with an air inlet 1211, the evaporator 14 is located close to the air inlet 1211 and between the fan 13 and the air inlet 1211. At this time, the air entering the top air duct 113 from the air inlet 1211 is first cooled by the evaporator 14, thereby improving the cooling efficiency.

[0033] It should be noted that when the evaporator 14 is configured with heat dissipation fins, the heat dissipation fins can guide the air so that the air entering the top air duct 113 from the air inlet 1211 is cooled in an orderly manner and then transported to the side air duct 112 in an orderly manner.

[0034] In one embodiment, the combination continues. Figures 3 to 6The protective cover 12 also includes a water-blocking bracket 125, which includes a first part 1251 and a second part 1252. The first part 1251 is connected to the connecting plate 123, and the second part 1252 is disposed on the first part 1251 and extends upward from the first part 1251. Both the first part 1251 and the second part 1252 abut against the side plate 124. A first receiving groove 1271 is formed between the second part 1252, the connecting plate 123 and the front plate 121. The first receiving groove 1271 is used to receive the evaporator 14. When water droplets fall from the evaporator 14 into the first receiving groove 1271, the water falling into the first receiving groove 1271 slides down from the connecting plate 123 and collects at the bottom of the first receiving groove 1271. A second receiving groove 1272 is formed between the base plate 122, the connecting plate 123 and the second part 1252. The second receiving groove 1272 is used to accommodate the fan 13. Since the second part 1252 can separate the first receiving groove 1271 and the second receiving groove 1272, the water collected in the first receiving groove 1271 cannot enter the second receiving groove 1272. Therefore, the water in the first receiving groove 1271 can be prevented from being carried by the fan 13 into the side air duct 112 and then into the receiving space of the refrigeration chamber 11.

[0035] In one embodiment, reference is made to... Figures 3 to 6 The connecting plate 123 is configured as an arc-shaped panel recessed towards the receiving groove 127, and the arc-shaped panel at the bottom of the first receiving groove 1271 is inclined from the front plate 121 towards the first part 1251. The arc-shaped panel configuration allows the connecting plate 123 to guide airflow more gently. At the same time, the arc-shaped panel design can also prevent users from being scratched by sharp corners when picking up or placing items. In addition, since the arc-shaped panel at the bottom of the first receiving groove 1271 is inclined from the front plate 121 towards the first part 1251, when water on the evaporator 14 drips down into the first receiving groove 1271, the water gathers away from the front plate 121 along the inclined direction of the connecting plate 123, thereby preventing water from flowing out of the air inlet 1211 of the front plate 121 and affecting other items in the refrigeration chamber 11.

[0036] In one embodiment, reference is made to... Figure 3 and Figure 4 The protective cover 12 also includes a drainage section 126, which abuts against the connecting plate 123 and encloses a drainage groove 1261 between the connecting plate 123 and the connecting plate 123. The drainage groove 1261 communicates with the first receiving groove 1271 and is located at the bottom of the first receiving groove 1271. A drain outlet 1262 is provided at the bottom of the drainage groove 1261. Water collected at the bottom of the first receiving groove 1271 can flow out through the drainage section 126, thereby preventing long-term water accumulation in the first receiving groove 1271 from polluting the air inside the refrigeration chamber 11. At the same time, timely drainage of accumulated water through the drainage groove 1261 can also prevent the fan 13 from bringing some water into the refrigeration chamber 11 during operation.

[0037] In one embodiment, reference is made to... Figure 3 and Figure 4 The drainage section 126 is located at the end of the connecting plate 123 away from the side plate 124. The drainage section 126 and the side plate 124 are respectively positioned at both ends of the shaped plate 120, which improves the stability of the protective cover 12 within the cooling chamber 11. Furthermore, the drainage section 126 can also function as the side plate 124, thus forming a receiving groove 127 together with the shaped plate 120 and the side plate 124. This receiving groove 127 better gathers the airflow within the top air duct 113, resulting in a better airflow guiding effect.

[0038] In one embodiment, combined with Figures 3 to 6 The protective cover 12 also includes a guide section 128, within which a clearance groove 1280 is provided. The guide section 128 is located at the bottom of the base plate 122, and the clearance groove 1280 communicates with the second receiving groove 1272, allowing the fan 13 to extend into the clearance groove 1280. The guide section 128 can accommodate the fan 13 and protect it, preventing external damage to the fan 13 and also collecting the air guided by the fan 13 and directing the airflow to the side duct 112.

[0039] In one embodiment, reference continues... Figures 3 to 6 The airflow guide 128 includes a side baffle 1281 and an air guide plate 1282. The side baffle 1281 and the air guide plate 1282 together enclose a clearance groove 1280, and the air guide plate 1282 is recessed in the direction of the clearance groove 1280. The recess of the air guide plate 1282 in the direction of the clearance groove 1280 can reduce the space occupied in the refrigeration chamber 11, thereby providing space for other items in the refrigeration chamber 11. In addition, the width of the air guide plate 1282 gradually decreases from away from the side air duct 112 to closer to the side air duct 112. Therefore, the air guide plate 1282 can guide and converge the air discharged from the top air duct 113 by the fan 13 to the side air duct 112, preventing the cooled air from flowing in other directions, thereby increasing the proportion of cooled air in the side air duct 112 flowing into the refrigeration chamber 11, and further improving the cooling efficiency.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
