Description

Technical Field

[0001] This utility model relates to the field of refrigerator refrigeration unit technology, specifically a vertical commercial refrigerator refrigeration unit. Background Technology

[0002] Upright commercial refrigerators offer a wide temperature control range. The refrigerator compartment temperature can generally be flexibly adjusted between 0 and 10°C, a range suitable for storing various fresh foods, beverages, dairy products, etc. For example, 0-4°C is the ideal temperature range for preserving most leafy vegetables, effectively extending their shelf life; while 5-10°C is suitable for storing sauces, canned goods, and other similar products.

[0003] Upright commercial refrigerators are equipped with powerful refrigeration systems. Many upright commercial refrigerators have rapid cooling and quick-freezing functions. The rapid cooling function can lower the temperature of food placed inside to a suitable range in a short time. For example, when newly purchased beverages or fresh food are placed in the refrigerator, the refrigerator can lower its temperature to the set temperature within 15-30 minutes to ensure the freshness of the food.

[0004] The core of a refrigerator's refrigeration unit is based on a vapor compression refrigeration cycle. This cycle mainly includes four basic processes: compression, condensation, throttling, and evaporation. Its purpose is to transfer heat from inside the refrigerator to the outside, thereby lowering the internal temperature and achieving a cooling effect.

[0005] Regarding the aforementioned technologies, the inventor believes that the following defects exist: the refrigeration unit has problems such as difficulty in sealing corners at the inlet and outlet pipe positions; when the top surface of the cabinet is below the dew point temperature, condensation will occur in certain areas of the refrigeration unit; since the top of the cabinet is flat, the condensation will eventually flow into the cabinet from the air vent, causing the air vent to drip water; at the same time, insects can easily enter the refrigerator from the refrigeration unit's drain outlet, contaminating the food. Utility Model Content

[0006] To address the technical problems of existing refrigeration units, such as difficulty in sealing corners at inlet and outlet pipe locations, water dripping from vents, and insects easily entering the refrigerator through drain outlets and contaminating food, this utility model provides a vertical commercial refrigerator refrigeration unit.

[0007] This utility model is achieved using the following technical solution: a vertical commercial refrigerator refrigeration unit, including a cabinet, a unit base fixedly connected to the top of the cabinet, a lower unit foam provided at one top end of the unit base, an upper unit foam connected to the top of the lower unit foam, and a fixed connection at the bottom of the upper unit foam to the top of the unit base. A first metal strip and a second metal strip are provided at both ends of the upper unit foam. A compressor is provided at the other top end of the unit base, a condenser assembly is provided on one side of the compressor, and the bottom of the condenser assembly is located at the top of the unit base.

[0008] The unit has an axial flow fan and an evaporator inside the lower foam section. The axial flow fan has an air inlet at one end and an air outlet on one side. The evaporator has a water collection tray at the bottom and pre-embedded foam at the bottom.

[0009] Preferably, the foam on the unit is fixed to the top of the unit base by a first metal strip and a second metal strip.

[0010] Preferably, the top of the unit base is provided with high-density sponge, and the high-density sponge has an opening processed in the center for passing wires and pipes.

[0011] Preferably, the pre-embedded foam is provided with a step at both the air inlet and the air outlet, and the step height is 5mm.

[0012] Preferably, the water receiving tray is V-shaped, and the evaporator is placed at an angle on top of the water receiving tray.

[0013] Preferably, one end of the air inlet is connected to the freezer compartment, one end of the air outlet is connected to the refrigerator compartment, and the other end of the air outlet is located on one side of the evaporator.

[0014] Preferably, the bottom of the unit base is provided with two injection molded parts.

[0015] Preferably, a duct is provided at one end of the interior of the lower foam of the unit, and the duct is located on one side of the evaporator.

[0016] Preferably, a water storage grid is provided on one side of the foam on the unit.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In use, the first and second metal pressure strips fix the foam on the unit to the base of the unit, so that the foam on the unit completely covers the foam on the bottom of the unit, thus forming a double sealing structure.

[0019] When in use, this utility model solves the problem of difficulty in sealing corners at the inlet and outlet of pipelines by opening a hole in the center of the high-density sponge for wires and pipes.

[0020] When in use, this utility model adds a 5mm high step around the pre-embedded foam air vent to block water vapor, effectively solving the problem of water dripping from the air inlet and outlet. At the same time, the pre-embedded foam air vent helps to prevent misalignment during production.

[0021] In use, this invention delivers hot air from the refrigerator compartment's air outlet directly to the evaporator via a duct, preventing hot and cold air from coming into contact at the air outlet and effectively preventing ice and frost from forming at the air outlet.

[0022] When in use, the hot air blown out by the condenser fan passes through the water storage compartment, keeping the water temperature at the drain outlet always above zero, eliminating the risk of freezing. By ensuring that water is always present in the water storage compartment, it can effectively prevent reptiles from entering the refrigerator through the drain outlet and contaminating the food.

[0023] When in use, this invention tilts the evaporator at a certain angle, so that during defrosting, large frost layers will slowly slide down the evaporator fins. At the same time, the evaporator continues to heat up, ensuring that the large frost melts into water when it slides to the lowest point, thus solving the problem of poor defrosting of the drip tray.

[0024] When this utility model is in use, because the top surface of the box is below the dew point temperature, condensation will occur in some areas inside the box. Since the top of the box is flat, the water vapor will eventually flow into the box from the air vent. By adding a 5mm high step at the air vent of the pre-embedded foam, the water vapor is blocked, effectively solving the problem of water dripping from the air inlet and outlet. At the same time, the pre-embedded foam of the air vent also helps to prevent misalignment during product production, avoiding affecting the installation of the refrigeration unit.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] Example 1: Please refer to Figure 1 - Figure 7 This embodiment of a vertical commercial refrigerator refrigeration unit includes a cabinet 1. The top of the cabinet 1 is fixedly connected to a unit base 7. A lower unit foam 5 is provided at one end of the top of the unit base 7. The top of the lower unit foam 5 is connected to an upper unit foam 6. The bottom of the upper unit foam 6 is fixedly connected to the top of the unit base 7. A first metal pressure strip 13 and a second metal pressure strip 14 are provided at both ends of the upper unit foam 6. A compressor 3 is provided at the other end of the top of the unit base 7. A condenser assembly 4 is provided on one side of the compressor 3. The bottom of the condenser assembly 4 is located at the top of the unit base 7. An axial flow fan 2 and an evaporator 11 are provided inside the lower unit foam 5. An air inlet 9 is provided at the bottom of one end of the axial flow fan 2. An air outlet 10 is provided on one side of the evaporator 11. A water receiving tray 12 is provided at the bottom of the evaporator 11. A pre-embedded foam 8 is provided at the bottom of the lower unit foam 5.

[0035] In this process, the foam 6 on the unit is fixed to the top of the unit base 7 by the first metal pressure strip 13 and the second metal pressure strip 14. The foam 6 on the unit completely covers the foam 5 below the unit, forming two sealing structures. The first metal pressure strip 13 and the second metal pressure strip 14 are used in front of and behind the foam 6 on the unit, thereby fixing the foam 6 on the unit to the unit base 7 together. The foam 6 is fixed in place by an interference fit with 6 screws.

[0036] Furthermore, the top of the unit base 7 is equipped with high-density sponge. By making holes in the center of the high-density sponge and other materials to pass through wires and pipes, the problem of difficult sealing at corners in the inlet and outlet pipe positions is solved. This effectively blocks air flow, reduces water vapor caused by frost and ice, improves cooling efficiency, and reduces the overall power consumption of the unit.

[0037] Furthermore, the pre-embedded foam 8 has a step at both the air inlet 9 and the air outlet 10. During the cooling process, the box 1 generates a large amount of cold energy. While exchanging heat with the inside of the box, a small amount of cold energy is transferred to the top of the box 1 through the insulation layer. When the ambient temperature and humidity reach a certain level, the top surface of the box 1 is lower than the dew point temperature, and condensation will occur in some areas inside the box. Since the top of the box is flat, the condensation will eventually flow into the box from the air outlet. By adding a 5mm high step at the air outlet of the pre-embedded foam 8, the water vapor is blocked, effectively solving the problem of water dripping from the air inlet 9 and the air outlet 10. At the same time, the pre-embedded foam of the air outlet also helps to prevent misalignment during product production and avoids affecting the installation of the refrigeration unit.

[0038] Furthermore, one end of the air inlet 9 is connected to the freezer compartment, one end of the air outlet 10 is connected to the refrigerator compartment, and the other end of the air outlet 10 is located on one side of the evaporator 11. The refrigerator compartment of the dual-temperature refrigerator returns air to the freezer compartment. Since the refrigerator compartment is above zero temperature and the freezer compartment is below zero temperature, the contact between hot and cold air will form frost. This utility model, by thickening the independent channel, directly sends the hot air from the air outlet 10 of the refrigerator compartment to the evaporator, avoiding the contact between hot and cold air at the air outlet 10, and effectively preventing the air outlet 10 from freezing and frosting.

[0039] Furthermore, when defrost water flows out of the drain, it first accumulates in the water storage compartment. When the water storage compartment is full, the water level is 9mm high, and the lowest point of the drain is 5mm from the bottom of the water storage compartment. This results in the drain being completely submerged 4mm below the water surface in the water storage compartment. During defrosting, the water temperature here is around 1-5 degrees Celsius. When defrosting is complete and cooling begins, the condenser fan blows hot air through the water storage compartment, carrying away the cold air in the water. This causes the water in the water storage compartment to heat up, keeping the water temperature at the drain above zero and eliminating the risk of freezing. The defrosting cycle is once every 4 hours, ensuring that there is always water in the water storage compartment. This also effectively prevents insects from entering the refrigerator through the drain and contaminating the food.

[0040] Furthermore, the drip tray 12 is V-shaped, and the evaporator 11 is placed at an angle on top of the drip tray 12. When the frost on the cabinet 1 is thick, large pieces of frost may fall onto the drip tray 12 during defrosting, resulting in poor defrosting. This invention solves the problem of poor defrosting of the drip tray 12 by tilting the cabinet 1 at a certain angle. During defrosting, large pieces of frost will slowly slide down the evaporator fins to the bottom. At the same time, the evaporator continues to heat up, ensuring that the large pieces of frost melt into water when they slide to the lowest point.

[0041] Furthermore, two injection molded parts 15 are provided at the bottom of the unit base 7. The two injection molded parts 15 are used to prevent water leakage and prevent foam from breaking. A duct 16 is provided at one end of the interior of the lower foam 5 of the unit. The duct 16 is located on one side of the evaporator 11. A water storage grid 17 is provided on one side of the upper foam 6 of the unit.

[0042] Working principle: The upper foam 6 of the unit is fixed to the base 7 of the unit by the first metal pressure strip 13 and the second metal pressure strip 14, so that the upper foam 6 completely covers the lower foam 5 of the unit, thus forming a double sealing structure; by opening the center of the high-density foam for wires and pipes, the problem of difficult sealing at corners in the inlet and outlet pipes can be solved; by adding a 5mm high step at the air outlet of the pre-embedded foam 8, water vapor is blocked, effectively solving the problem of water dripping from the air inlet 9 and the air outlet 10, and the pre-embedded foam of the air outlet helps to prevent misalignment during production; by thickening the independent channel, the heat of the cold storage air outlet 10 is... Air is delivered directly to the evaporator, preventing hot and cold air from coming into contact at the air outlet 10, effectively eliminating the risk of icing and frost formation at the air outlet 10. The hot air blown out by the condenser fan passes through the water storage compartment, ensuring that the water temperature at the drain outlet remains above zero, eliminating the risk of icing. The water storage compartment always contains water, effectively preventing insects from entering the refrigerator through the drain outlet and contaminating food. By tilting the evaporator at a certain angle, large frost layers will slowly slide down the evaporator fins to the bottom during defrosting. At the same time, the evaporator continues to heat up, ensuring that large frost layers melt into water when they reach the lowest point, thus solving the problem of poor defrosting in the drip tray 12.

[0043] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
