A refrigeration device

Abstract

This invention provides a refrigeration device that solves the problem of poor odor removal in current refrigeration equipment. It includes a shelf with ventilation holes inside the cabinet; an air duct inside the cabinet; an exhaust fan inside the cabinet with its outlet connected to the air duct; a storage box located at the air outlet of the air duct, detachably connected to the cabinet, with an air inlet on its bottom surface; an exhaust vent inside the cabinet and above the storage box; and an odor absorbent inside the storage box. When the exhaust fan operates, it draws air from inside the cabinet through the ventilation holes in the shelf, drawing odorous air dispersed in various areas of the cabinet into the air duct, and then into the storage box. The odorous air comes into full contact with the odor absorbent in the storage box, which is either activated carbon or a mineral absorbent, removing the odor from the air. The purified air then flows back into the cabinet through the exhaust vent, achieving highly efficient odor purification.

Description

Technical Field

[0001] This utility model relates to the field of food refrigeration and preservation technology, specifically to a refrigeration device. Background Technology

[0002] Refrigeration equipment, used for storing goods at low temperatures, is widely used in many fields such as households, commercial retail, food processing, and pharmaceutical preservation. Its core function is to maintain a low-temperature environment inside the refrigerator through refrigeration units to inhibit the growth of microorganisms and the spoilage of goods, thereby extending their freshness or shelf life. As people's requirements for storage quality continue to increase, in addition to ensuring stable refrigeration performance, odor control inside the refrigerator has gradually become one of the core pain points of concern for users.

[0003] To address the odor problem, some refrigeration equipment places independent odor adsorption modules inside the cabinet. These adsorption structures are mostly fixed or placed randomly. Due to the low contact efficiency between the adsorbent and the air inside the cabinet, they can only treat the surrounding air in a small area and cannot achieve odor purification throughout the entire cabinet space, resulting in poor odor removal. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a refrigeration device that solves the problem of poor odor removal effect in current refrigeration equipment.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A refrigeration device includes a housing, the housing being equipped with a refrigeration unit, and further includes:

[0007] A shelf is installed inside the box, and the shelf is provided with ventilation holes;

[0008] The air duct is located inside the enclosure.

[0009] An exhaust fan is installed inside the housing, and the exhaust fan's outlet is connected to the air duct.

[0010] A storage box is installed at the air outlet of the air duct. The storage box is detachably connected to the box body. The bottom surface of the storage box is provided with an air inlet for communicating with the air duct.

[0011] The air vent is located inside the box and above the storage box;

[0012] Odor absorbent is placed inside the storage box.

[0013] The storage box and the housing are fitted together in a drawer-like manner. The storage box has elastic positioning pins on both sides, and the housing has grooves for engaging the elastic positioning pins.

[0014] A sealing ring is provided between the storage box and the box body.

[0015] The equipment also includes a door installed on the housing, the door having a double-layered observation window.

[0016] The exhaust fan is equipped with a protective cover.

[0017] The inner wall of the box is provided with a heat insulation layer, and the inner side of the heat insulation layer is provided with an anti-condensation coating.

[0018] The box is also equipped with a germicidal lamp.

[0019] The beneficial effects of this utility model are:

[0020] When the exhaust fan is running, it can drive the air inside the chamber to flow through the ventilation holes of the shelf, drawing the odorous air dispersed in various areas of the chamber into the air duct, and then into the storage box. The odorous air comes into full contact with the odor adsorbent in the storage box. The odor adsorbent is activated carbon pack or mineral adsorbent, which removes the odor from the air. The purified air flows back into the chamber from the air outlet, forming a complete cycle of "full-area air collection - directional odor removal - clean return", achieving efficient odor purification of the entire chamber space. This solves the drawback of traditional adsorption structures that can only treat local air, and greatly improves the odor removal efficiency. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] In the embodiments, such as Figure 1 , Figure 2 As shown, a refrigeration device includes a housing 1, wherein a refrigeration unit is installed in the housing 1, and further includes:

[0027] A storage board 2 is installed inside the box body 1, and the storage board 2 is provided with ventilation holes 3;

[0028] Air duct 4 is installed inside housing 1.

[0029] An exhaust fan 5 is installed inside the housing 1, and the air outlet of the exhaust fan 5 is connected to the air duct 4.

[0030] The storage box 6 is located at the air outlet of the air duct 4. The storage box 6 is detachably connected to the box body 1. The bottom surface of the storage box 6 is provided with an air inlet 7 for communicating with the air duct 4.

[0031] Vent 8 is located inside the housing 1 and above the storage box 6;

[0032] Odor absorbent 9 is placed inside storage box 6.

[0033] The ventilation holes on the shelf allow air to pass through the interior of box 1.

[0034] When the exhaust fan 5 is running, it can drive the air inside the box to flow through the ventilation holes 3 of the shelf 2, drawing the odorous air dispersed in various areas of the box 1 into the air duct 4, and then into the storage box 6. The odorous air comes into full contact with the odor adsorbent 7 in the storage box 6. The odor adsorbent is activated carbon pack or mineral adsorbent, which removes the odor from the air. The purified air flows back into the box from the air outlet 8, forming a complete cycle of "full-area air collection - directional odor removal - clean return", achieving efficient odor purification of the entire box space. This solves the drawback of traditional adsorption structures that can only treat local air, and greatly improves the odor removal efficiency.

[0035] In the embodiments, such as Figure 1 , Figure 2 As shown, the storage box 6 and the housing 1 are fitted in a drawer-type manner. The storage box 6 has elastic positioning pins 10 on both sides, and the housing 1 has grooves 11 inside for engaging with the elastic positioning pins 10. The odor absorbent 9 is easy to replace, and the engagement of the elastic positioning pins 10 and grooves 11 ensures that the storage box 6 is stably positioned within the housing 1.

[0036] In the embodiments, such as Figure 3 As shown, a sealing ring 12 is provided between the storage box 6 and the housing 1. This ensures the airtightness of the housing 1 and the storage box 6, prevents cold air from escaping between the housing 1 and the storage box 6, ensures a stable low-temperature environment inside the housing 1, and reduces refrigeration energy consumption.

[0037] In the embodiments, such as Figure 3 As shown, the system also includes a door 13 installed on the enclosure 1, the door 13 having a double-layered observation window 14. The double-layered observation window 14 is made of stainless steel glass, with a sealing element between the stainless steel glass panes. The type, quantity, and status of the stored items inside the enclosure 1 can be clearly viewed through the double-layered observation window 14 without opening the door 13, avoiding frequent opening of the door and resulting loss of cold air inside the enclosure.

[0038] In the embodiments, such as Figure 1 As shown, the exhaust fan 5 is equipped with a protective cover 15. This prevents stored items from coming into contact with the exhaust fan 5, ensuring its normal operation and also ensuring the safety of personnel when maintaining the housing 1.

[0039] In the embodiments, such as Figure 1 As shown, the inner wall of the box 1 is provided with a heat insulation layer 16, and the inner side of the heat insulation layer 16 is provided with an anti-condensation coating 17. This reduces heat exchange between the inside and outside of the box 1, maintains the stability of the low-temperature environment inside the box 1, and prevents condensation from dripping and contaminating the stored items, thus preventing the growth of microorganisms.

[0040] In the embodiments, such as Figure 1 As shown, the box 1 is also equipped with a germicidal lamp 18. The germicidal lamp 18 can inhibit and kill microorganisms in the box 1, thereby improving the cleanliness of the environment inside the box 1.

[0041] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
