Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically a middle partition air duct structure for refrigeration equipment. Background Technology

[0002] Existing refrigeration equipment (such as cigar cabinets and wine cabinets) typically includes a central partition within the cabinet, dividing it into an upper and lower storage compartment. For example, Chinese Patent No. CN202323060727.2 discloses a heating and humidifying structure for a cigar cabinet, and Chinese Patent No. CN202221922657.X discloses a dual-airflow temperature-controlled cigar cabinet. The upper and lower storage compartments are set to different temperatures to meet the storage requirements of different items. However, due to gravity, when the upper storage compartment is set to a lower temperature while the lower storage compartment is set to a higher temperature, the cold air in the upper compartment sinks due to gravity and leaks into the lower storage compartment through the foam air inlet of the central partition. This results in the actual temperature in the lower storage compartment being lower than the set temperature, affecting the storage of the items. Therefore, further improvements are necessary. Utility Model Content

[0003] The present invention aims to provide a middle partition air duct structure for a refrigeration equipment to overcome the shortcomings of the prior art.

[0004] A refrigeration equipment with a middle partition air duct structure designed for this purpose includes a cabinet. The cabinet is provided with a middle partition assembly, which separates an upper storage chamber and a lower storage chamber. An internal air duct is provided in the cabinet. The middle partition assembly is provided with a connecting port, a fan, and a partition air duct. The upper storage chamber is connected to the internal air duct, and the lower storage chamber is connected to the connecting port. The fan is located on the connecting port, and the partition air duct is connected to both the internal air duct and the connecting port.

[0005] The partition air duct is arranged horizontally on the middle partition assembly and is composed of branch air ducts and converging air ducts. The branch air ducts are connected to the air ducts inside the cabinet, and one end of the converging air duct is connected to the branch air ducts and the other end is connected to the connecting port.

[0006] The confluence air duct is provided as one and extends linearly, and the branch air duct is provided as several and extends linearly outward from one end of the confluence air duct.

[0007] The intermediate partition assembly includes an upper plate and a lower plate, which are spaced vertically apart and are separated by a heat insulation plate. The communication port is longitudinally through the heat insulation plate, and the lower plate is also provided with a lower plate opening corresponding to the communication port.

[0008] The heat insulation board has a Y-shaped groove recessed on its surface or bottom, and the upper or lower plate covers the Y-shaped groove, forming the branch air duct and the confluence air duct.

[0009] The fan is an axial flow fan and is fixedly mounted on the upper plate and / or the lower plate.

[0010] A connector is provided between the upper plate and the lower plate, and the plates are fixed to each other at intervals through the connector. The heat insulation plate is also provided with clearance space corresponding to the connector.

[0011] The upper and lower panels are respectively provided with flanges on their outer peripheries, and are respectively supported and fixed to the inner wall of the cabinet by the flanges.

[0012] The cabinet has a side recessed cavity on its side wall, and an inner side plate is provided on the recessed cavity. The inner side plate covers the side recessed cavity, and the two form the cabinet air duct. The cabinet air duct extends longitudinally. The inner side plate has an upper storage chamber ventilation hole and a side opening. The upper storage chamber is connected to the cabinet air duct through the upper storage chamber ventilation hole. The partition air duct is connected to the cabinet air duct through the side opening.

[0013] The intermediate partition assembly is also equipped with a control panel, which is connected to the fan control panel.

[0014] This utility model utilizes the interconnection between the upper storage chamber and the cabinet air duct, the lower storage chamber and the connecting port, and the partition air duct and the cabinet air duct and the connecting port respectively, so that the upper storage chamber is connected to the lower storage chamber through the cooperation of the cabinet air duct, the partition air duct and the connecting port, and a fan is installed on the connecting port.

[0015] When the lower storage chamber needs to be cooled, the fan operates and draws the cool air from the upper storage chamber into the cabinet air duct and the partition air duct in sequence, and finally into the lower storage chamber through the connecting port, thereby achieving the cooling of the lower storage chamber.

[0016] When the temperature in the lower storage chamber reaches the set value, the fan stops working, and the air ducts and partition ducts inside the cabinet cannot circulate air. This effectively prevents the cold air in the upper storage chamber from entering the lower storage chamber, keeping the temperature in the lower storage chamber constant. This ensures that the temperatures in the upper and lower storage chambers are both within the set values ​​and do not interfere with each other, thus meeting the different storage requirements of the stored items and making it highly practical.

[0025] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1-8 The intermediate partition air duct structure of this refrigeration equipment includes a cabinet 1, an intermediate partition assembly inside the cabinet 1, and an upper storage chamber 2 and a lower storage chamber 3 separated by the intermediate partition assembly. An internal air duct 4 is provided inside the cabinet 1. A connecting port 5, a fan 6 and a partition air duct are provided on the intermediate partition assembly. The upper storage chamber 2 is connected to the internal air duct 4, and the lower storage chamber 3 is connected to the connecting port 5. The fan 6 is installed on the connecting port 5. The partition air duct is connected to the internal air duct 4 and the connecting port 5 respectively.

[0028] In this embodiment, the upper storage chamber 2 is connected to the cabinet air duct 4, the lower storage chamber 3 is connected to the connecting port 5, and the partition air duct is connected to the cabinet air duct 4 and the connecting port 5 respectively. Thus, the upper storage chamber 2 is connected to the lower storage chamber 3 through the cooperation of the cabinet air duct 4, the partition air duct, and the connecting port 5. At the same time, a fan 6 is installed on the connecting port 5.

[0029] When the lower storage chamber 3 needs to be cooled, the fan 6 operates and draws the cold air from the upper storage chamber 2 into the cabinet air duct 4 and the partition air duct in sequence, and finally into the lower storage chamber 3 through the connecting port 5, thereby achieving the cooling of the lower storage chamber 3.

[0030] When the temperature of the lower storage chamber 3 reaches the set value, the fan 6 stops working, and the air duct 4 and partition air duct inside the cabinet cannot circulate air. This effectively blocks the cold air in the upper storage chamber 2 from entering the lower storage chamber 3, keeping the temperature of the lower storage chamber 3 constant. This ensures that the temperatures of the upper storage chamber 2 and the lower storage chamber 3 are both within the set value and do not interfere with each other, thus meeting the different storage requirements of the stored items and making it highly practical.

[0031] The partition air duct is horizontally arranged on the middle partition assembly and consists of branch air duct 7 and converging air duct 8. The branch air duct 7 is connected to the air duct 4 inside the cabinet. One end of the converging air duct 8 is connected to the branch air duct 7, and the other end is connected to the connecting port 5.

[0032] There is one confluence duct 8 that extends linearly, and several branch ducts 7 that extend linearly outward from one end of the confluence duct 8.

[0033] In this embodiment, the ends of the multiple branch air ducts 7 are respectively connected to the air duct 4 inside the cabinet, and the other ends of the multiple branch air ducts 7 are respectively connected to one end of the converging air duct 8, so that the cold air flowing in the multiple branch air ducts 7 can be merged on the converging air duct 8 and finally flow to the connecting port 5.

[0034] The multiple branch air ducts 7 can increase the flow of cold air, and the converging air ducts 8 can make the cold air finally converge at a designated location, reducing the waste of cold air.

[0035] The middle partition assembly includes an upper plate 9 and a lower plate 10. The upper plate 9 and the lower plate 10 are spaced apart vertically, and a heat insulation plate 11 is provided between them. The connecting port 5 is longitudinally through the heat insulation plate 11. The lower plate 10 is also provided with a lower plate opening 12 corresponding to the connecting port 5.

[0036] In this embodiment, the heat insulation plate 11 can reduce the temperature interference between the upper storage chamber 2 and the lower storage chamber 3. In addition, the cold air flowing to the connecting port 5 enters the lower storage chamber 3 through the lower plate opening 12.

[0037] The heat insulation board 11 has a Y-shaped groove recessed on its surface or bottom. The upper plate 9 or the lower plate 10 covers the Y-shaped groove and forms a branch air duct 7 and a confluence air duct 8.

[0038] In this embodiment, the Y-shaped groove is recessed on the surface of the heat insulation plate 11, and the upper plate 9 is covered on the Y-shaped groove, forming a branch air duct 7 and a confluence air duct 8. That is, there are two branch air ducts 7, and they form a Y shape with the confluence air duct 8.

[0039] Fan 6 is an axial fan and is fixedly mounted on the upper plate 9 and / or the lower plate 10.

[0040] In this embodiment, the fan 6 is located on the connecting port 5 and is fixed to the lower plate 10 by fasteners. When the fan 6 is working, it achieves vertical air extraction. The air inlet of the fan 6 faces the converging air duct 8, and the air outlet faces the lower plate opening 12 and the lower storage chamber 3.

[0041] A connector 13 is provided between the upper plate 9 and the lower plate 10, and they are fixed to each other at intervals through the connector 13. The heat insulation plate 11 is also provided with a clearance 14 corresponding to the connector 13.

[0042] In this embodiment, the connector 13 is located on the clearance position 14. Its upper side is fixedly connected to the upper plate 9 by fasteners, and its lower side is fixedly connected to the lower plate 10 by fasteners, thereby realizing the fixation between the upper plate 9 and the lower plate 10, and at the same time forming a constant interval between the upper plate 9 and the lower plate 10.

[0043] The outer periphery of the upper shelf 9 and the lower shelf 10 are respectively provided with flanges 15, and are respectively supported by and fixed to the inner wall of the cabinet 1 through the flanges 15.

[0044] In this embodiment, the outer peripheries of the upper plate 9 and the lower plate 10 are respectively supported by the inner wall of the cabinet 1 through the flange 15, and fasteners are provided on the flange 15 to achieve fixation with the inner wall of the cabinet 1.

[0045] The side wall of the cabinet 1 is provided with a side recess, and an inner side plate 16 is provided on the recess. The inner side plate 16 covers the side recess, and the two form an internal air duct 4. The internal air duct 4 extends longitudinally. The inner side plate 16 is provided with an upper storage chamber ventilation hole 17 and a side opening 18. The upper storage chamber 2 is connected to the internal air duct 4 through the upper storage chamber ventilation hole 17. The partition air duct is connected to the internal air duct 4 through the side opening 18.

[0046] In this embodiment, the side recess is set on the rear side wall of the cabinet 1, and the inner side plate 16 is fixed to the rear side wall of the cabinet 1 by fasteners and covers the side recess, so that the rear side of the cabinet 1 forms a longitudinally extending cabinet air duct 4. In addition, the Y-shaped branch air duct 7 and the converging air duct 8 are arranged horizontally, and the cabinet air duct 4 and the connecting port 5 are arranged vertically. Therefore, the branch air duct 7 and the converging air duct 8 are perpendicular to each other with the cabinet air duct 4 and the connecting port 5, respectively, which can effectively prevent cold air from entering the lower storage chamber 3 through the cabinet air duct 4, the branch air duct 7, the converging air duct 8 and the connecting port 5 when the fan 6 is not working.

[0047] A control panel 19 is also provided on the middle partition assembly. The control panel 19 is electrically connected to the fan 6, so that the user can control the fan 6 through the control panel 19.

[0048] In this embodiment, temperature sensors are respectively installed in the upper storage chamber 2 and the lower storage chamber 3, and temperature detection is achieved using the temperature sensors respectively.
