Description

Technical Field

[0001] This utility model relates to a freezer. Background Technology

[0002] Currently available freezers typically consist of two parts: the cabinet and the refrigeration system. The core components of the refrigeration system include the evaporator, compressor, expansion valve, and condenser. The evaporator is generally located inside the freezer compartment, achieving freezing through the evaporation and heat absorption of the low-temperature refrigerant. The compressor, expansion valve, and condenser, on the other hand, are often installed externally or semi-externally in a central compartment at the back or bottom of the cabinet, responsible for the compression, throttling, and condensation of the refrigerant. This arrangement effectively utilizes space and ensures centralized management of the core components, but it also introduces a series of inconveniences in use and maintenance.

[0003] On the one hand, the refrigeration equipment compartment generates significant heat during prolonged operation. If the heat dissipation design is inadequate, it can easily lead to excessively high operating temperatures of the condenser and compressor, reduced cooling efficiency, increased machine noise, and shortened component lifespan. On the other hand, to ensure a seamless appearance and user safety, traditional freezers often use fixed decorative panels or conceal the equipment compartment behind the cabinet. While this conceals the refrigeration components, routine cleaning, maintenance, or filter replacement requires complete disassembly of the cabinet or the use of specialized tools, causing considerable inconvenience to users. Furthermore, the placement of fixed decorative panels and ventilation holes often fails to balance aesthetics and ventilation. If the ventilation holes are too small, heat dissipation will be insufficient; if they are too large, it will damage the overall appearance and may allow dust and impurities to enter the equipment compartment, affecting cooling performance. Utility Model Content

[0004] The purpose of this invention is to provide a new type of freezer that can ensure efficient heat dissipation of the refrigeration system while also taking into account the aesthetics and ease of maintenance of the entire unit.

[0005] The purpose of this utility model is achieved as follows:

[0006] A freezer includes a cabinet and a refrigeration system. The refrigeration system includes an evaporator, a compressor, an expansion valve, and a condenser. The cabinet has a freezer compartment and an equipment housing compartment. The evaporator is located in the freezer compartment, and the compressor, expansion valve, and condenser are all located in the equipment housing compartment.

[0007] The freezer compartment is equipped with a cabinet door, which is hinged to the cabinet body for opening or closing the corresponding freezer compartment;

[0008] The equipment compartment is equipped with a decorative panel, which is detachably mounted on the cabinet for opening or closing the equipment compartment;

[0009] The decorative panel has a heat dissipation opening near the condenser, and the heat dissipation opening is equipped with a heat dissipation grid baffle, which is detachably installed on the heat dissipation opening.

[0010] The side wall of the cabinet has ventilation holes spaced apart at the locations corresponding to the equipment storage compartment.

[0011] By placing the evaporator in the freezer compartment and centrally housing the compressor, expansion valve, and condenser in the equipment housing, the refrigeration efficiency of the freezer compartment is ensured, while also isolating the components that generate more heat and noise from the user's view.

[0012] The spatial division between the freezer compartment and the equipment storage compartment makes it more convenient to maintain, repair or replace the refrigeration system without having to disassemble the entire cabinet.

[0013] The overall structure is compact, which not only enhances the overall appearance but also makes effective use of the internal space of the machine.

[0014] The freezer compartment and equipment storage compartment are designed to be separate, with the equipment storage compartment having an independent opening and closing structure. Maintenance personnel can quickly open the decorative panel to inspect or replace parts without affecting the operation of the freezer compartment, which greatly shortens maintenance time.

[0015] The objective of this utility model can also be achieved by the following technical measures:

[0016] Furthermore, the decorative panel has ventilation holes spaced apart above the ventilation opening.

[0017] Adding heat dissipation holes to the decorative panel, and cooperating with the heat dissipation openings at the condenser location, forms a double ventilation path from top to bottom, which can accelerate the natural convection of hot air and reduce the temperature inside the equipment room.

[0018] It improves the heat exchange conditions of the condenser, enhances the operational stability of the refrigeration system, and extends the service life of key components and reduces the frequency of maintenance due to more efficient heat dissipation.

[0019] Furthermore, it also includes a control panel, which is mounted on the decorative panel. The refrigeration system is electrically connected to the control panel, and the control panel controls the start and stop of the refrigeration system.

[0020] The control panel is integrated into the decorative panel, allowing users to intuitively and conveniently control the start, stop, and operating status of the refrigeration system. The control panel, integrated into the detachable decorative panel, is both aesthetically pleasing and easy to remove. During maintenance, electrical connections can be quickly disconnected and the control panel removed, facilitating fault diagnosis and repair of the control system or refrigeration components. This simplifies system wiring and panel layout, significantly reducing operational steps and time costs when servicing the refrigeration system.

[0021] Furthermore, the decorative panel has an installation cavity, and the bottom of the installation cavity has a heat dissipation opening. The installation cavity is provided with slots at intervals around the heat dissipation opening. The heat dissipation grille baffle is provided with a locking block. The heat dissipation grille baffle is placed inside the installation cavity, and the locking block is inserted into the slot, so that the heat dissipation grille baffle is detachably installed on the heat dissipation opening.

[0022] • Tool-free quick engagement is achieved through the mounting cavity and slot on the decorative panel and the clip on the heat dissipation grille baffle. Users or maintenance personnel can remove the heat dissipation grille baffle by simply pressing the clip, making it convenient to clean the dust on the condenser fins daily.

[0023] This design ensures that the heat dissipation grille is stable and not easily detached, while also providing excellent accessibility for maintenance, reducing the difficulty of subsequent maintenance.

[0024] Furthermore, it also includes a barrier plate with spaced openings, the barrier plate being detachably installed within the heat dissipation openings.

[0025] The baffle plate is detachably installed inside the heat dissipation opening. Its spacing allows air circulation while effectively preventing larger foreign objects from entering the equipment housing.

[0026] Furthermore, the top of the heat dissipation grille baffle has a notch, which forms a handle for easy gripping by the user.

[0027] The notch at the top of the heat dissipation grille forms a handle that is easy to grip, making it easier and more comfortable for users to remove the grille.

[0028] Furthermore, it also includes bolts. The top and bottom of the decorative panel have first bolt holes spaced apart, and the top and bottom of the cabinet corresponding to the equipment storage compartment have second bolt holes. The bolts pass through the first bolt holes and lock the second bolt holes to achieve the connection between the decorative panel and the cabinet.

[0029] The decorative panel is connected to the cabinet by bolts through the first and second bolt holes to ensure the installation strength and stability of the decorative panel;

[0030] Bolts are installed at both the top and bottom to further prevent the decorative panels from loosening, thus improving overall safety and durability.

[0031] When the refrigeration system needs to be inspected, the entire decorative panel can be disassembled by simply removing a few bolts, providing a convenient and quick access for maintenance work while ensuring structural safety and vibration resistance in daily use.

[0032] The beneficial effects of this utility model are as follows:

[0033] This utility model features a partitioned design for the freezer compartment and the equipment storage compartment. The equipment storage compartment has an independently opening and closing structure, allowing maintenance personnel to quickly open the decorative panel for inspection or replacement of parts without affecting the operation of the freezer compartment, thus significantly shortening maintenance time.

[0034] This invention adds heat dissipation holes to the decorative panel, which, together with the heat dissipation openings at the condenser location, form a double ventilation path from top to bottom, which can accelerate the natural convection of hot air and reduce the temperature inside the equipment's containment room.

[0035] This utility model achieves tool-free quick engagement through the mounting cavity and slot on the decorative panel and the locking block on the heat dissipation grille baffle. Users or maintenance personnel can remove the heat dissipation grille baffle simply by pressing the locking block, making it convenient for daily cleaning of dust on the condenser fins. This design not only ensures that the heat dissipation grille baffle is stable and not easy to fall off, but also provides excellent maintenance accessibility and reduces the difficulty of subsequent maintenance.

[0036] This utility model uses the first and second bolt holes to connect the decorative panel to the cabinet body, ensuring the installation strength and stability of the decorative panel. When the refrigeration system needs to be repaired, only a few bolts need to be removed to disassemble the entire decorative panel, providing a convenient and quick access for maintenance work, while ensuring structural safety and vibration resistance in daily use.

[0037] In this invention, the notch at the top of the heat dissipation grille baffle forms a handle that is easy to grip, making it easier and more comfortable for users to disassemble the grille. Attached Figure Description
