Abstract
Description
Technical Field
[0001] This utility model relates to the field of ice maker technology, specifically a double-layer rotomolded water storage tank. Background Technology
[0002] The ice bucket collection container inside an ice maker is an important component in the ice-making process. It is used to collect and store the formed ice. Ice buckets are typically made of durable, freeze-resistant materials, such as food-grade plastic or stainless steel. These materials not only withstand low temperatures but are also easy to clean, ensuring hygiene standards.
[0003] However, the above-mentioned existing technologies have the following shortcomings: Most ice bucket collection boxes on the market are made of sheet metal or single-layer structure. When they are filled with a certain amount of ice and ice water, they are very prone to overflow due to condensation, which will contaminate the ice maker and make it damp and easy for bacteria to grow. Utility Model Content
[0004] The purpose of this utility model is to solve the technical problem that most ice bucket collection boxes on the market are made of sheet metal or single-layer structure, which are prone to overflow due to condensation when holding a certain amount of ice and ice water, resulting in contamination of the ice maker and making it damp and prone to bacterial growth. The present invention provides a double-layer rotomolded water storage tank.
[0005] To achieve the above objectives, the present invention adopts the following technical solution;
[0006] The present invention relates to a double-layer rotomolded water storage tank, comprising a storage container; the storage container having a concave receiving groove; a threaded pipe being fixedly connected to the concave receiving groove; a filter pipe being threadedly connected to the threaded pipe; and a shell extraction groove being provided inside the storage container.
[0007] Furthermore, the concave storage groove is provided with an external convex groove.
[0008] Furthermore, the storage container is symmetrically provided with locking grooves.
[0009] Furthermore, the storage container is symmetrically provided with raised edges.
[0010] The double-layer rotomolded water tank provided by this utility model has the following beneficial effects:
[0011] 1. This utility model, by creating a shell-extraction groove inside the storage container, allows the air inside the groove to form an insulation layer, thus blocking the heat exchange between the concave storage groove and the outer surface of the storage container. This keeps the concave storage groove at a consistently low temperature, significantly reducing the amount of condensation on the outer surface of the storage container and minimizing the amount of condensation that wets the interior of the ice maker, thereby preventing overflow problems caused by condensation buildup. This provides a more reliable and convenient solution for the use of ice bucket collection boxes. Attached Figure Description

[0017] The labels in the diagram are as follows: 1. Storage container; 2. Outer protrusion; 3. Locking groove; 4. Shell extraction groove; 5. Concave storage groove; 6. Threaded tube; 7. Filter tube; 8. Protruding edge; 9. Clearance groove. Detailed Implementation
[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.
[0021] Please see Figure 1-4 As shown, a double-layer rotomolded water storage tank includes a storage container 1 for storing waste ice and wastewater. A concave receiving groove 5 is provided in the storage container 1. A threaded pipe 6 is connected and fixed within the concave receiving groove 5. A stainless steel filter pipe 7 is threaded onto the threaded pipe 6, allowing the melted ice water in the concave receiving groove 5 to flow onto the filter pipe 7 for filtration under gravity, and then discharge through the threaded pipe 6, thus enabling wastewater recycling. An extraction groove 4 is provided within the storage container 1, forming an insulation layer with the air inside. This prevents heat exchange between the concave receiving groove 5 and the outer surface of the storage container 1, maintaining a consistently low temperature within the concave receiving groove 5. This significantly reduces the amount of condensation on the outer surface of the storage container 1, minimizing the condensation that wets the interior of the ice maker and creates a humid environment. This fundamentally avoids overflow problems caused by condensation accumulation, providing a more reliable and convenient solution for ice bucket collection tanks.
[0022] The concave storage groove 5 has an outward protrusion groove 2, which allows a portion of the ice cube space to fall in conjunction with the ice maker to protrude, thus accepting a larger range of dripping water and ice cubes.
[0023] The storage container 1 has symmetrically arranged locking grooves 3, which can be stably fixed inside the ice maker by cooperating with the locking block through the locking grooves 3.
[0024] The storage container 1 has symmetrical protruding edges 8, which, together with the mounting plate inside the ice maker, can withstand greater weight and be stably supported and fixed inside the ice maker.
[0025] The storage container 1 has a clearance groove 9, which, in conjunction with the corresponding locking block, can be stably fixed inside the ice maker.
[0026] Storage container 1 is made of plastic, making it easy to manufacture a water tank with an internal cavity through rotational molding.
