Both the first opening and the second opening are integrally connected to the inner cavity. The top of the cabinet body 1 is provided with an upper door 2 that closes the first opening, and the bottom of the cabinet body 1 is provided with a front door 3 that closes the second opening.

[0021] The top-opening door 2 is preferably a glass door, which can be slidably connected to the top of the cabinet 1 along its length (left or right) or along its width (back and forth). Alternatively, the top-opening door 2 can be a hinged hinge to the top of the cabinet 1, opening and closing the first opening by flipping it open. The structure and connection method of the top-opening door 2 are existing technologies and will not be described in detail here.

[0022] The front door 3 is located at the bottom front of the cabinet 1 and is a downward-opening door. A handle 32 is provided on the front side of the front door 3. The front door 3 includes a housing 31 and an insulation layer 32 located inside the housing 31. A sealing strip 33 is provided on the side of the insulation layer 32. When the front door 3 is closed, the insulation layer 32 is embedded in the second opening, and the sealing strip 33 adheres to the inner wall of the cabinet 1, effectively sealing the second opening and preventing cold leakage at the front door 3. When the front door 3 is open, the insulation layer 32 is flush with the bottom of the inner cavity of the cabinet 1, serving as a temporary storage platform for easy access to items.

[0023] The front door 3 is movably connected to the cabinet 1 via hinge 4 and support rod 5. The hinge 4 is located at the bottom of the cabinet 1 and includes a hinge shaft and a first hinge piece and a second hinge piece hinged on the hinge shaft. The first hinge piece is fixedly connected to the bottom of the front side of the cabinet 1 by bolts, and the second hinge piece is fixedly connected to the inner wall of the front door 3 by bolts.

[0024] Support rods 5 are provided on both sides of the front door 3, including a first fixing part 51, a second fixing part 52, a first hinge rod 53, and a second hinge rod 54. Grooves 11 are respectively provided on the left and right sides of the cabinet 1. The first fixing part 51 is fixedly connected to the upper part of the groove 11 by bolts, and the second fixing part 52 is fixedly connected to the inner wall of the front door 3 by bolts. The upper end of the first hinge rod 53 is hinged to the first fixing part 51, and the lower end of the first hinge rod 53 is hinged to the upper end of the second hinge rod 54. The lower end of the second hinge rod 54 is hinged to the second fixing part 52. Limiting blocks 55 are alternately provided on the side walls at the connection points of the first hinge rod 53 and the second hinge rod 54. The limiting blocks 55 block each other and limit the angle at which the first hinge rod 53 and the second hinge rod 54 open, so that the opening angle of the first hinge rod 53 and the second hinge rod 54 in the open state of the front door is less than 180°. When the front door 3 is closed, the support rod 5 is stored in the groove 11; when the front door 3 is open, the support rod 5 pulls and supports the opening and closing of the front door 3.

[0025] The inner cavity is provided with two layers of baskets 6, and items are placed in the baskets 6. The baskets 6 include an upper basket placed on the upper part of the inner cavity and a lower basket placed at the bottom of the inner cavity. The bottom of the baskets 6 is provided with casters.

[0026] When it is necessary to replenish the items in the lower basket 6 to the upper basket, open the front door 3 and the top door 2. The front door 3 can serve as a temporary platform during the process of retrieving and placing items. It is not necessary to completely remove the lower basket 6; the lower basket 6 can be pulled out and placed on the front door 3, and items can be retrieved to replenish the upper basket 6. Alternatively, the lower and upper baskets can be interchanged, with the lower basket replacing the empty upper basket. This horizontal freezer allows for the storage and retrieval of items by pushing in or pulling out the baskets 6. All items within the entire cabinet 1 are easily accessible, and the bottom space of the cabinet 1 is fully utilized, significantly improving efficiency and reducing workload.

[0027] Furthermore, in some embodiments, magnetic strips are embedded in the top and / or sides of the front door 3, and the lower opening frame is made of magnetically conductive metal. The magnetic strips attract the front door 3 to keep it closed. In some embodiments, a lock is also provided in the front door 3 to lock the front door 3 and prevent it from being opened arbitrarily.

[0028] The cabinet 1 is equipped with a refrigeration system to provide cooling for the interior cavity. The refrigeration system includes a compressor 71, a condenser 72, a throttling device, and an evaporator connected in a circulating manner. The compressor 71 is located in the compressor compartment 7 on one side of the cabinet 1. To increase the space inside the cabinet 1, the condenser 72 and the evaporator are respectively mounted on the outer wall of the interior cavity and the inner wall of the cabinet 1 shell. Foamed insulation material is filled between the outer wall of the interior cavity and the inner wall of the cabinet 1 shell. Specifically, the evaporator includes an upper evaporator 73 and a lower evaporator 74. The upper evaporator 73 is mounted in the upper area of ​​the interior cavity in a ring structure, arranged based on the first pipe gap; the lower evaporator 74 is mounted in the lower area of ​​the interior cavity in a U-shaped structure, fitting against the left and right side walls and the rear wall of the cabinet 1, and arranged based on the second pipe gap. Since the main heat load of the horizontal freezer comes from the air exchange at the first opening at the top, and cold air is dense and tends to sink, an evaporator pipe layout with denser pipes at the top and sparser pipes at the bottom is adopted. The pipes of the upper evaporator 73 in the upper area are arranged more densely, while the pipes of the lower evaporator 74 in the lower area are arranged more sparsely. That is, the gap between the first pipes is smaller than the gap between the second pipes, thereby optimizing the distribution of cold energy and improving the temperature uniformity inside the cabinet 1.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
