Description

Technical Field

[0001] The utility model relates to the technical field of refrigerating boxes, and more specifically, to a top air duct structure of a refrigerating box. Background Art

[0002] As the quality of human life improves, the global demand for cold chain transportation is growing. The mode of shipping refrigerated goods has shifted from professional refrigerated ship transportation to refrigerated container transportation, so the loading capacity of refrigerated containers on container ships is on the rise. Refrigerated containers are divided into two types: air-cooled and water-cooled according to the cooling method of the condenser of the refrigeration unit. The air-cooled condenser is made of a copper coil with aluminum fins on the outside. The condensing fan is located on the top of the coil, and the fan opening is controlled by the condensing pressure. When the unit is running, air is sucked in from the bottom of the coil and blown out horizontally from the upper fan grille. The water-cooled condenser is made of a container and a coil, and needs to be equipped with an independent cooling water system.

[0003] As disclosed in application number CN202110794909.9, a duct device is suitable for being arranged in a compartment, comprising an outer duct cover, an inner duct cover and at least one fan, the fan is suitable for being arranged in the inner duct cover, the inner duct cover is suitable for being arranged in the outer duct cover, a first duct is formed between the outer duct cover and the inner duct cover, a second duct is formed in the inner duct cover, the second duct is connected to the inner chamber of the compartment, a return air structure is provided on multiple end faces of the outer duct cover, the air in the compartment is suitable for entering the first duct from the return air structure, and the fan is suitable for directing the air from the first duct to the second duct. By providing multiple return air structures on the outer duct cover, the air can be returned from multiple directions of the compartment to ensure sufficient circulation of air in all directions inside the compartment, thereby ensuring the consistency and uniformity of the temperature at all positions inside the compartment.

[0004] However, the existing 40-foot refrigerated container is relatively long. For the top-outlet refrigeration machine, an air duct needs to be installed on the top of the container to guide the air. The existing air duct is generally fixed on the top of the container by a combination of hooks and rubber bands. The temperature inside the container is usually below zero. Over time, the rubber band is prone to breakage, causing the air duct to fall off. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a top air duct structure of a refrigerator to solve one or more of the above-mentioned problems.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A refrigerated box top air duct structure, comprising

[0008] The mounting seat is a special-shaped part, one end of which is connected to the top surface of the refrigerator, and the other end is provided with a fixing rope inside and an opening at the end;

[0009] A canvas air duct, the ends of which are provided with flanges, and the two ends are connected to the fixing ropes in two different mounting seats in the refrigerator;

[0010] A plurality of vents are provided on the surface of the canvas air duct.

[0011] Furthermore, the flange is formed by bending the end of the canvas air duct and then piercing and fixing it with rivets.

[0012] Furthermore, one end of the mounting seat mounted on the top surface of the refrigerator is a flat plate structure, and one end of the mounting seat provided with a fixing rope is a hollow tube ring structure.

[0013] Furthermore, two ends of the fixing rope are detachably connected to the inside of one end of the mounting seat tube ring structure.

[0014] Furthermore, Velcro is provided at the ventilation opening of the canvas air duct, and a detachable blocking piece is provided on the ventilation opening.

[0015] Furthermore, the opening at the end of the mounting seat is inclined upward;

[0016] The vents are arranged in an array on the bottom end surface of the canvas air duct.

[0017] In summary, the utility model has the following beneficial effects: the special-shaped structure of the mounting seat strengthens the closure of the fixing rope and the flange, improves the sealing, and is beneficial to improving the cold air delivery efficiency; the cold air enters the canvas duct from the air inlet and is blown out from the vent below. The air outlet can be optionally equipped with a sealing piece through Velcro, which can be adjusted according to different working conditions, and manual intervention can be performed to make the overall cold air distribution in the box uniform; the canvas duct can be removed and replaced by pulling out the fixing rope passed through the middle of the mounting seat, which is convenient and quick; the flanged docking can eliminate the influence of low temperature on the connection structure, and the stability is better.

[0021] Example:

[0022] The following is combined with Figure 1-2 The utility model is described in further detail.

[0023] A refrigerated box top air duct structure, such as Figure 1 As shown, it mainly includes a canvas duct 3 and a mounting seat 1. The mounting seat 1 is divided into a connecting end and a mounting end. The connecting end is connected to the top surface of the refrigerator box and is used to fix the mounting seat 1 itself, and the mounting end is used to dock the canvas duct 3. The connecting end of the mounting seat 1 is generally a flat plate structure, which is installed on the relatively stable and regular inner top surface of the refrigerator box, and is generally installed by functional parts such as rivets. The mounting end of the mounting seat 1 is a hollow pipe ring structure, and a component for docking the fixing rope 2 is left inside. The fixing rope 2 is generally docked and installed inside this end of the mounting seat 1 along the front and back directions. The mounting end of the mounting seat 1 has an opening obliquely facing the upper right corner, so that the canvas duct 3 will have a tendency to fall while naturally hanging down, and it can fit closely with the opening of the mounting end at the bottom. The size of the opening gap is appropriately adjusted, and the upper part of the opening is filled downward to further improve the sealing of the edge of the canvas duct 3. The two ends of the canvas duct 3 are flanged 4, and are respectively connected to the fixing rope 2 in the mounting seat 1 symmetrically arranged at the two corners inside the refrigerator. The flange 4 of the canvas air duct 3 is formed by bending the end edge downward and then piercing and fixing it with rivets. In this way, whether the fixing rope 2 is installed first and then the flange 4 is bent to connect, or the flange 4 is bent first and then the fixing rope 2 is installed, the connection between the mounting seat 1 and the canvas air duct 3 can be achieved. The end edge of the canvas air duct 3 can also be sewn in advance. This method can only be achieved by passing the uninstalled fixing rope 2 through the canvas air duct 3 and then installing it inside the mounting seat 1. A plurality of vents are provided at the bottom of the canvas air duct 3, and the vents can be regularly distributed or irregularly distributed.

[0024] like Figure 2 As shown, the canvas duct 3 is a wide-band duct structure made of canvas material. The vent at the bottom of the canvas duct 3 is provided with a Velcro 5 sub-sticker or a mother sticker, and the blocking piece is provided with a Velcro 5 mother sticker or a sub-sticker, and the two are matched to achieve the blocking of a single vent. It can be set according to different working conditions, which is flexible and convenient. When the canvas duct 3 needs to be replaced, just remove the fixing rope 2. The cold air from the end cold machine outlet flows out for refrigeration at a predetermined position to ensure that the cold air of the whole box is evenly distributed.

[0025] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
