Description

MODULAR REFRIGERATION UNIT

FIELD OF THE INVENTION

The present disclosure relates to refrigeration units and more particularly, relates to a modular refrigeration unit and methods of forming a main cabinet of the modular refrigeration unit.

BACKGROUND

Refrigerators are widely used around the world for preservation of commodities, for example, food items, medicines, and any other product that needs to be preserved in a cold environment. A refrigerator is usually made of a main cabinet for storing the commodities and a door generally hinged to the main cabinet providing access to the interiors of the refrigerator, for example, to the stored commodities.

Currently, the main cabinet of the refrigerators is formed as a single body component, for example, by joining sheet-metal. Once formed by the sheet-metal joining, the main cabinet may then be foamed for insulation. Thereafter, remaining components are assembled on the main cabinet to form the refrigerator, and the refrigerator is then dispatched to a customer. Generally, such refrigerators are of large dimensions and warrant immense care in handling in order to ensure a leakage-free structure. Accordingly, their handling within a manufacturing facility and their transportation from the manufacturing facility to a customer location are cumbersome tasks, which involve a significant expenditure as well.

Moreover, as is generally known, based on different desired storage capacities, refrigerators have to be manufactured with different dimensions for different applications. For example, dimensions of a refrigerator to be installed in a shop for storing beverages may be different than the dimensions of a refrigerator to be used in a large warehouse. Accordingly, main cabinets with different dimensions are to be manufactured to comply with the different demands of the consumers. In order to accommodate the manufacturing of main cabinets with different dimensions, a number of moulds corresponding to each dimension are required, as each mould can only be used to form main cabinets of a predefined dimension. Considering the cost associated with such moulds, an overall cost of manufacturing of the refrigerators is consequently increased. Additionally, maintenance and storing of a large number of moulds pose cannot be neglected as well.

As illustrated, the modular refrigeration unit 100 may include a portion of the at least one guiding pin assembly 302 and a portion of the at least one camlock assembly 304 at the periphery of each of the panels 104. Similarly, a corresponding engaging portion of the at least one guiding pin assembly 302 and a corresponding engaging portion of the at least one camlock assembly 304 may be disposed on a corresponding periphery of another panel 104 that is to be coupled with the panel 104. In an embodiment, each pair of panels 104 may be coupled with each other by about 3-6 camlock assemblies 304 and about 4-6 guiding pin assemblies 302.

For the sake of clarity, constructional and operational features of the at least one guiding pin assembly 302 and the at least one camlock assembly 304 are explained with respect to the coupling of the first panel 104-1 and the second panel 104-2. As would be appreciated by a person skilled in the art, the same description is equally applicable to the coupling of any two panels 104 of the present disclosure to form the main cabinet 102, without departing from the scope of the present disclosure.

In an embodiment, the at least one guiding pin assembly 302 may be disposed in parts on the first panel 104-1 and the second panel 104-2. The at least one guiding pin assembly 302 may be adapted to align the first panel 104-1 with the second panel 104-2 for subsequent coupling by the at least one camlock assembly 304. Figure 4 illustrates the at least one guiding pin assembly 302, according to an embodiment of the present disclosure. In an embodiment, the at least one guiding pin assembly 302 may include, but is not limited to, at least one pin disposed on the first panel 104-1 and at least one pin receiving component disposed on the second panel 104-2. In an embodiment, the at least one pin and the at least one pin receiving component may be formed of plastic.

Figure 4A illustrates the at least one pin 402 of the at least one guiding pin assembly 302, according to an embodiment of the present disclosure. Figure 4B illustrates the at least one pin receiving component 404 of the at least one guiding pin assembly 302, according to an embodiment of the present embodiment. For coupling the first panel 104-1 with the second panel 104-2, the first panel 104-1 may be aligned with the second panel 104-2 by engaging the at least one pin 402 with the at least one pin receiving component 404. In particular, the at least one pin receiving component 404 may accommodate the at least one pin 402 for aligning the first panel 104-1 with the second panel 104-2. Once aligned, the first panel 104-1 and the second panel 104-2 may be coupled with each other by the at least one camlock assembly 304. The at least one camlock assembly 304 may be disposed in parts on the first panel 104-1 and the second panel 104-2. Figure 5 illustrates different views of the at least one camlock assembly 304, according to an embodiment of the present disclosure. In particular, Figure 5A illustrates a side view of the at least one camlock assembly 304, according to an embodiment of the present disclosure. The at least one camlock assembly 304 may include, but is not limited to, a first sub-assembly 502, a second sub- assembly 504, and a hook 506 disposed in one of the first sub-assembly 502 and the second sub- assembly 504. Figure 5B illustrates a front view of the first sub-assembly 502, according to an embodiment of the present disclosure. Similarly, Figure 5C illustrates a front view of the second sub-assembly 504, according to an embodiment of the present disclosure. In the present embodiment, the hook 506 is shown to be disposed in the second sub-assembly 504. In other embodiments, the hook 506 may be disposed in the first sub-assembly 502, without departing from the scope of the present disclosure.

In an embodiment, the first sub-assembly 502 may be disposed on the first panel 104-1. Further, the second sub-assembly 504 may be disposed on the second panel 104-2. The second sub-assembly 504 may be adapted to be aligned with the first sub-assembly 502, for example, when the at least one pin 402 engages with the at least one pin receiving component 404 of the at least one guiding pin assembly 302. Further, the hook 506 may be adapted to rotate when the first sub-assembly 502 is aligned with the second sub-assembly 504. The rotation of the hook 506 may engage the first sub-assembly 502 with the second sub-assembly 504, for coupling the first panel 104-1 with the second panel 104-2. In particular, owing to the rotation, the hook 506 may extend out of the second sub-assembly 504 and enter the first sub-assembly 502 to engage with a corresponding engaging slot therein.

Further, in particular, the first sub-assembly 502 and the second sub-assembly 504 may be disposed within the first panel 104-1 and the second panel 104-2, respectively. Therefore, the first sub-assembly 502 and the second sub-assembly 504 may not be visible from outside. Considering that the hook 506 is disposed within the second sub-assembly 504 in the present embodiment, the second sub-assembly 504 may include a tool insertion slot 508. In an embodiment where the hook 506 is disposed within the first sub-assembly 502, the first sub- assembly 502 may include the tool insertion slot 508, without departing from the scope of the present disclosure.

In an embodiment, the second panel 104-2 may include a hole on a surface facing the inside of the main cabinet 102. The hole may be formed such that the hole aligns with the tool insertion slot 508 of the second sub-assembly 504. Therefore, the tool insertion slot 508 may be accessed by a tool through the hole on the inside surface of the second panel 104-2. In an embodiment, the tool may access the tool insertion slot 508 for rotating the hook 506 to engage the first sub-assembly 502 with the second sub-assembly 504 and therefore, for coupling the first panel 104-1 with the second panel 104-2. In an embodiment, an Allen key may be used as the tool to rotate the hook 506.

In an embodiment, the modular refrigeration unit 100 may include a protection cap adapted to cover the hole on the inside surface of the second panel 104-2 of the main cabinet 102. Figure 6 illustrates a plurality of protection caps 602, according to an embodiment of the present disclosure.

Figure 7 illustrates a sectional side view and a sectional front view of the main cabinet 102, according to an embodiment of the present disclosure. In particular, Figure 7A illustrates the sectional side view of the main cabinet 102, according to an embodiment of the present disclosure. Further, Figure 7B illustrates the back view of the main cabinet 102, according to an embodiment of the present disclosure. As shown, the panels 104 are coupled to each other by the at least one guiding pin assembly 302 and the at least one camlock assembly 304.

Figure 8 illustrates a sequence of assembly of components to form the modular refrigeration unit 100, according to an embodiment of the present disclosure. For the sake of brevity, the details of assembly are not explained in detail in the description of Figure 8. As shown, the panels 104 are aligned and coupled together to form the main cabinet 102. Further, the cooling chamber 106 is disposed at the bottom of the main cabinet 102. Subsequently, the door 108 may be connected with the main cabinet 102 to form the modular refrigeration unit 100 of the present disclosure. Figure 9 illustrates a method 900 of forming the main cabinet 102, according to an embodiment of the present disclosure. For the sake of brevity, constructional and operational features of the modular refrigeration unit 100 that are already explained in the description of Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, Figure 6, Figure 7, and Figure 8 are not explained in detail in the description of Figure 9.

At a block 902, the method 900 includes forming the panels 104 as separate components. At a block 904, the method 900 includes foaming each of the panels 104 with PUF insulation. At a block 906, the method 900 includes aligning the panels 104 with each other for coupling. The panels 104 may be aligned with each other by the at least one guiding pin assembly 302. At a block 908, the method 900 includes coupling the panels 104 with each other to form the main cabinet 102. The panels 104 may be coupled with each other by the at least one camlock assembly 304.

In an embodiment, the method 900 may include rotating, by the tool, the hook 506 disposed in one of the first sub-assembly 502 and the second sub-assembly 504 of the at least one camlock assembly 304. The first sub-assembly 502 may be disposed on the first panel 104- 1, and the second sub-assembly 504 may be disposed on the second panel 104-2. The hook 506 may be rotated when the first sub-assembly 502 may be aligned with the second sub-assembly 504, to engage the first sub-assembly 502 with the second sub-assembly 504 for coupling the first panel 104-1 with the second panel 104-2.

As would be gathered, the panels 104 may be adapted to be conveniently coupled with each other to form the main cabinet 102 of the modular refrigeration unit 100. Further, owing to the flexible modularity, the modular refrigeration unit 100 can be conveniently assembled at any location, for example, at a customer location or at a warehouse. Therefore, inconvenience and cost associated with handling and transportation of the refrigerators are significantly reduced. Moreover, each panel 104 is separately foamed and then coupled with other panels 104 by using the at least one guiding pin assembly 302 and the at least one camlock assembly 304. Such coupling ensures integrity to an overall structure of the modular refrigeration unit 100. Accordingly, the modular refrigeration unit 100 of the present disclosure doesn’t have any sort of foam or air leakage. With regard to ease of assembly, in an example, it would take about 20-30 minutes to assemble the modular refrigeration unit 100. Further, only one tool may be sufficient to assemble the modular refrigeration unit 100 or at least the main cabinet 102. Therefore, assembling the panels 104 to form the main cabinet 102 and consequently the modular refrigeration unit 100 is easier as well as faster as compared to the installation of the existing refrigerators. As a result, with minimum use of tools and workforce, the modular refrigeration unit 100 of the present disclosure can be assembled at any location. Also, in case of movement, the modular refrigeration unit 100 can easily be disassembled as well. In addition, as far as the manufacturing of the panels 104 is concerned, a single mould can be used for manufacturing the panels 104 of different dimensions. Accordingly, cost associated with having multiple moulds for different dimensions as was the case in the existing techniques, is eliminated. Rather, in the present disclosure, just by using one mould, multiple panels 104 with different dimensions can be manufactured. Therefore, the modular refrigeration unit 100 of the present disclosure is easy to assemble, cost-effective, of high quality, flexible in implementation, convenient to handle, and leakage free.

While specific language has been used to describe the present disclosure, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein. The drawings and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment.
