Description

Technical Field

[0001] This utility model relates to the field of food storage cabinet technology, and in particular to a vertical air-cooled food storage cabinet. Background Technology

[0002] In the food preservation field, upright air-cooled refrigerators are widely used in supermarkets, convenience stores, and the catering industry due to their rapid cooling and convenient temperature control. However, existing upright air-cooled refrigerators still have some problems in actual use: poor cooling uniformity. Traditional refrigerators mostly use a single air duct design, which makes it easy for cold air to accumulate in local areas, resulting in large temperature differences at different heights and positions inside the refrigerator, affecting the preservation effect of food.

[0003] Therefore, this application provides a vertical air-cooled refrigerator to meet the needs. Utility Model Content

[0004] The purpose of this application is to provide a vertical air-cooled refrigerator, which aims to solve the problem that traditional refrigerators often use a single air duct design, which makes it easy for cold air to accumulate in local areas and affect the preservation effect of food.

[0005] To achieve the above objectives, this application provides the following technical solution: a vertical air-cooled refrigerator, comprising a unit cabinet and a cabinet body, the cabinet body being disposed on the top surface of the unit cabinet, and a placement board being disposed on the top surface of the unit cabinet;

[0006] The unit cabinet contains a condenser and a liquid receiver pump, and the liquid receiver pump is connected to the condenser via a conduit.

[0007] An evaporation coil is installed between the unit cabinet and the placement plate, and the evaporation coil is connected to the liquid storage pump through a conduit.

[0008] A cooling fan is installed next to the evaporator coil, and an air duct assembly is installed on the inner wall of the cabinet. The cooling fan is connected to the air duct assembly through the air duct bracket.

[0009] The evaporator coil, in conjunction with the cooling fan, can quickly generate and deliver cool air. The duct support adopts a multi-section folded plate design, and the air inlet is precisely connected to the duct components, reducing the loss of cool air during transportation and enabling the cool air to reach the target area efficiently. At the same time, the liquid receiver pump drives the condensate to circulate between the condenser and the evaporator coil, improving heat exchange efficiency and further enhancing the cooling effect, while reducing energy consumption while ensuring cooling capacity.

[0010] Preferably, the top surface of the placement plate is provided with a bottom air vent and a drain outlet.

[0011] Preferably, a partition plate is provided below the placement plate, and a diversion plate is provided above the partition plate, with the refrigeration fan and evaporator coil placed on the diversion plate.

[0012] The unit cabinet and the cabinet body adopt an upper and lower combination design. The internal components such as placement plates, air diversion plates, and partition plates are arranged in layers. The components are closely connected and realize multiple functions such as cooling, air supply, and drainage in a limited space. This not only saves installation space but also facilitates later maintenance and repair.

[0013] The symmetrically arranged drain outlets on the placement plate can quickly collect condensate. The combination of the diversion plate and the partition plate forms an orderly drainage channel. After the condensate drips from the drain outlet to the diversion plate, it passes through the partition plate through the connecting pipe and is discharged, which avoids the accumulation of condensate in the cabinet, prevents the growth of bacteria, protects the internal components of the equipment, and extends the service life of the refrigerator.

[0014] Preferably, the diversion plate has a U-shaped cross-section, and the middle part of the diversion plate is folded down and has perforations; holes are provided on the partition plate.

[0015] Preferably, the duct support is a multi-section folded plate, and an air inlet is provided on the top surface of the duct support, which is connected to the duct assembly.

[0016] Preferably, the air duct assembly includes an inner lining strip, mounting strips, and an inner lining plate. The inner lining strip is installed on the inner wall of the cabinet, and symmetrical mounting strips are provided on both sides of the inner lining strip. The two sets of mounting strips are connected by the inner lining plate, and multiple sets of side air vents are arranged vertically on the inner lining plate.

[0017] The length of the aforementioned inner lining panel is less than the length of the inner wall of the cabinet.

[0018] In summary, the technical effects and advantages of this utility model are as follows:

[0019] This invention utilizes a dual air outlet structure combining a bottom air vent and an air duct assembly, allowing cold air to be blown out from multiple locations, including the bottom, sides, and top of the cabinet. The bottom air vent directly delivers cold air to the bottom of the cabinet, while the air duct assembly, through channels formed by the inner lining strips, mounting strips, and inner lining panels, guides the cold air to different height areas within the cabinet. Under wind pressure, the air is then discharged from the side air vents and the top, achieving comprehensive, all-around cooling within the cabinet, effectively reducing temperature differences and ensuring uniform preservation of food.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: Reference Figure 1-7 The vertical air-cooled refrigerator shown includes a unit cabinet 1 and a cabinet body 8. The cabinet body 8 is installed on the top surface of the unit cabinet 1. A placement plate 12 is provided on the top of the unit cabinet 1. A diversion plate 4 and a partition plate 3 are arranged in sequence below the placement plate 12. An evaporator coil 6 is located between the placement plate 12 and the diversion plate 4. It works with a refrigeration fan 5 on the side to send cold air through the air duct bracket 7 to the air duct assembly, thereby achieving all-round cooling inside the cabinet body 8. A liquid storage pump is located in the unit cabinet 1 and is connected to a condenser 2 on the side through a conduit. It is used to deliver condensate to the condenser 2 and the evaporator coil 6.

[0031] As one embodiment of this invention, the placement plate 12 is provided with a bottom air vent 1200 and a drain outlet 1201. The bottom air vent 1200 and the drain outlet 1201 are symmetrically arranged, with one set for air outlet and the other set for collecting condensate.

[0032] As one embodiment of this invention, in order to allow the cold air at the bottom of the placement plate 12 to be delivered to the air duct assembly, air duct supports 7 are provided on both the left and right sides of the placement plate 12.

[0033] As one embodiment of this invention, the air duct support 7 is a multi-section folded plate, and an air inlet 700 is provided on the top surface of the air duct support 7. The air inlet 700 is connected to the air duct assembly. After passing through the air duct support 7, the cold air enters the air duct assembly from the air inlet 700.

[0034] As one implementation method in this embodiment, the air duct assembly has an inner lining strip 9 on the inner wall of the cabinet 8, and mounting strips 10 are symmetrically arranged on the left and right sides of the inner lining strip 9. The two sets of mounting strips 10 are connected by an inner lining plate 11 (the length of the inner lining plate 11 is shorter than the inner wall of the cabinet 8). The outer upper part of the inner lining plate 11 is provided with a side air vent 1100 that connects the inside and outside. Therefore, when the refrigeration fan 5 is working, the cold air passes through the air duct formed by the air duct assembly and is blown out from the top of the air duct assembly. During this process, under the action of wind pressure, some of the cold air is discharged from the side air vent 1100, thereby achieving full cooling of the refrigerator.

[0035] The working principle of this product is as follows: First, the condenser located in the unit cabinet 1 starts working, its purpose is to reduce the air temperature in the cabinet 8. The condenser 2 and the evaporator coil are connected by a pipe, so that the condensate circulates between the condenser 2 and the evaporator coil under the action of the liquid storage pump, thus realizing the condensate circulation. By starting the cooling fan 5, the cold air is driven by the airflow and discharged from the bottom air vent 1200 on the placement plate 12. Another part of the airflow passes through the channel built by the air duct bracket 7 and enters the space between the cabinet 8 and the inner lining plate 11 through the air inlet 700. Through the design of two sets of mounting strips 10 and one set of inner lining strips 9, the airflow is divided into two paths and blown out from the side air vent 1100 and the top respectively, realizing the cooling of the refrigerator at different heights.

[0036] When condensate or other liquids are present, they are collected through the drain outlet 1201 on the placement plate 12. After passing through the drain outlet 1201, the liquid drips onto the guide plate 4 and then through the pipe connected to the perforated plate 4. The pipe passes through the hole on the partition plate 3, thereby guiding and treating the condensate or other liquids.

[0038] Components not described in detail in this article are existing technologies.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
