[0004] Currently, the most common method for storing lard is to store it in a container and then place the container in a refrigerator. However, whenever the refrigerator door is opened to take out or store the lard, a large amount of the cold air originally stored in the refrigerator will quickly escape to the outside of the refrigerator due to convection with the outside hot air. This not only causes significant temperature fluctuations but also requires the refrigeration system to consume more energy to restore the set temperature, thus increasing energy consumption. Therefore, this utility model provides a cooling and storage device for lard. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cooling and storage device for lard, which solves the problem that whenever the refrigerator door is opened to take out or store lard, a large amount of low-temperature cold air originally stored in the refrigerator will quickly escape to the outside of the refrigerator due to convection with the outside hot air. This not only causes significant temperature fluctuations, but also requires the refrigeration system to consume more energy to restore the set temperature, thereby increasing energy consumption.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cooling and storage device for lard, comprising a refrigerator with a hollow interior. The top surface of the refrigerator is made of metal. Multiple circular holes communicating with the interior cavity are provided on the top of the refrigerator.

Guide holes that slidably connect with the guide posts are provided on the circular plate. Multiple first magnets are embedded near the edge of the top of the circular plate, and these first magnets can attract the metal material on the top surface of the refrigerator, thus sealing the circular holes.

[0007] Preferably, a second magnet is embedded at the top of the circular plate near the center, and a first sealing ring is also provided at the top of the circular plate, and the first sealing ring can be in close contact with the inner top surface of the refrigerator.

[0012] Beneficial effects

[0013] This invention provides a cooling and storage device for lard. Compared with the prior art, it has the following advantages:

[0014] 1. This cooling and storage device for lard, when using the oil storage component to store lard, places a barrel-shaped container into the refrigerator through the round hole. The weight of the barrel-shaped container causes the round plate to move downwards against the attraction force of the first magnet. At the same time, the metal plate at the bottom of the barrel-shaped container attracts the second magnet on the round plate, positioning the barrel-shaped container. Furthermore, the second sealing ring of the fixing plate contacts the top surface of the refrigerator for further sealing. In this way, the barrel-shaped container can move up and down close to the inner wall of the round hole, facilitating the storage and retrieval of lard. Meanwhile, the sealing component and the second sealing ring ensure the airtightness of the refrigerator, reducing the loss of cold air.

[0015] 2. This cooling and storage device for lard uses a temperature sensor to monitor the temperature inside the refrigerator in real time and send the temperature information to the controller. When the temperature is higher than the preset storage temperature, the controller sends a signal to the refrigeration unit to start working, delivering cold air into the refrigerator to lower the temperature. When the temperature reaches or falls below the preset temperature, the controller stops the refrigeration unit, thus achieving precise temperature control inside the refrigerator. This ensures that the lard is stored in a suitable low-temperature environment, preventing it from deteriorating due to excessively high temperatures and extending its shelf life.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides two technical solutions:

[0024] Figures 1-5 The first embodiment is shown: a cooling and storage device for lard, including a refrigerator box 1. The refrigerator box 1 has a hollow internal structure. The top surface of the refrigerator box 1 is made of metal. The top of the refrigerator box 1 has multiple circular holes 11 communicating with its internal cavity. Each circular hole 11 is equipped with an oil storage component 4. The refrigerator box 1 has multiple guide pillars 12 inside. The multiple guide pillars 12 are divided into groups of four, the same number as the number of circular holes 11. The guide pillars 12 are arranged along the height direction of the refrigerator box 1. The two ends of the guide pillars 12 are fixedly connected to the top surface and the bottom surface of the refrigerator box 1, respectively. Each group of guide pillars 12 is equipped with a sealing component 3. The sealing component 3 includes a circular plate 31, which is concentrically arranged with the circular holes 11. The circular plate 31 has guide holes 32 that are slidably connected to the guide pillars 12. Multiple first magnets 33 are embedded near the edge of the top of the circular plate 31. The first magnets 33 can be attracted to the metal material of the top surface of the refrigerator box 1, so that the circular holes 11 are blocked by the circular plate 31.

[0025] A second magnet 35 is embedded at the top of the circular plate 31 near the center. A first sealing ring 34 is also provided at the top of the circular plate 31, and the first sealing ring 34 can be in close contact with the inner top surface of the refrigerator 1.

[0026] The oil storage assembly 4 includes a barrel-shaped container 41, which can move up and down close to the inner wall of the round hole 11. A fixing plate 42 is fixedly installed on the outer wall of the barrel-shaped container 41 near the bottom. A second sealing ring 46 is provided at the bottom of the fixing plate 42. The second sealing ring 46 can be in close contact with the top surface of the refrigerator 1. A metal plate 47 is embedded at the bottom of the barrel-shaped container 41, and the metal plate 47 can attract the second magnet 35.

[0027] Specifically, in the initial state, the first magnet 33 on the circular plate 31 of the sealing component 3 is attracted to the metal material on the inner top surface of the refrigerator 1, while the first sealing ring 34 is in close contact with the inner top surface of the refrigerator 1, sealing the circular hole 11 to prevent cold air from leaking out and outside air from entering the refrigerator 1, thus achieving a sealing effect.

[0028] When using the oil storage component 4 to store lard, the barrel-shaped container 41 is placed into the refrigerator 1 through the round hole 11. The weight of the barrel-shaped container 41 will cause the round plate 31 to move downwards against the attraction force of the first magnet 33. At the same time, the metal plate 47 at the bottom of the barrel-shaped container 41 will attract the second magnet 35 on the round plate 31, positioning the barrel-shaped container 41. Furthermore, the second sealing ring 46 of the fixing plate 42 contacts the top surface of the refrigerator 1 for further sealing. In this way, the barrel-shaped container 41 can move up and down close to the inner wall of the round hole 11, facilitating the storage and retrieval of lard. Meanwhile, the sealing component 3 and the second sealing ring 46 ensure the airtightness of the refrigerator 1, reducing the loss of cold air.

[0029] A rotating seat 43 is symmetrically installed on the top of the fixed plate 42, and a handle 44 is movably provided between the two rotating seats 43. A bucket lid 45 is threadedly connected to the top of the barrel-type container 41.

[0030] Specifically, the barrel-shaped container 41 is lifted or lowered by operating the handle 44, which facilitates the storage and use of lard, and the barrel lid 45 is used to seal the barrel-shaped container 41.

[0031] Figures 1-5 The second embodiment is shown, the main difference from the first embodiment is that: a refrigeration unit 2 is installed on the outer surface of the refrigerator 1, and the air outlet of the refrigeration unit 2 penetrates the outer surface of the refrigerator 1 and extends into the interior.

[0032] A temperature sensor 5 is installed on the inner wall of one side of the refrigerator 1, and a controller 6 is installed on the outer surface of the refrigerator 1. The controller 6 is electrically connected to both the refrigeration unit 2 and the temperature sensor 5.

[0033] Specifically, temperature sensor 5 monitors the temperature inside the refrigerator 1 in real time and sends the temperature information to controller 6. When the temperature is higher than the preset storage temperature, controller 6 sends a signal to refrigeration unit 2 to start working, delivering cold air into the refrigerator 1 to lower the temperature. When the temperature reaches or falls below the preset temperature, controller 6 controls refrigeration unit 2 to stop working, thereby achieving precise temperature control inside the refrigerator 1, ensuring that lard is stored in a suitable low-temperature environment, preventing lard from deteriorating due to excessive temperature, and extending the shelf life of lard.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] Working principle: The barrel-shaped container 41 in the oil storage assembly 4 is placed inside the refrigerator 1 through the corresponding round hole 11. In the initial state, when the oil storage assembly 4 is not placed in a certain round hole 11, the round plate 31 of the sealing assembly 3 will be in a blocked state. At this time, the first magnet 33 on the round plate 31 is tightly attracted to the metal material of the inner top surface of the refrigerator 1 by its magnetic force. At the same time, the first sealing ring 34 at the top of the round plate 31 will also contact the inner top surface of the refrigerator 1. The two work together to effectively seal the round hole 11 tightly, preventing the low-temperature cold air inside the refrigerator 1 from escaping.

[0036] When the barrel-shaped container 41 containing lard needs to be placed in the refrigerator 1 for refrigeration, the user simply places the barrel-shaped container 41 on the circular plate 31. Under the influence of the oil storage component 4 and the gravity of the lard itself, this gravity overcomes the attraction between the first magnet 33 and the metal material on the top surface of the refrigerator 1, causing the circular plate 31 to move downwards. At the same time, the metal plate 47 at the bottom of the barrel-shaped container 41 will attract the second magnet 35 on the circular plate 31. As it continues to be placed downwards, the outer wall of the barrel-shaped container 41 will be tightly pressed against the inner wall of the circular hole 11. This tight fit prevents communication between the inside and outside of the refrigerator 1, effectively reducing the leakage of cold air during storage and ensuring the stability of the low-temperature environment inside the refrigerator 1.

[0037] When the oil storage component 4 needs to be removed, the user simply pulls the handle 44 on the barrel-shaped container 41 to lift it upwards. During this process, since the circular plate 31 is attracted to the metal plate 47 at the bottom of the barrel-shaped container 41 by the second magnet 35, the circular plate 31 will be lifted upwards along with the barrel-shaped container 41. After the barrel-shaped container 41 has moved upwards a certain distance, the first magnet 33 will again attract the metal material on the top surface of the refrigerator 1, and the circular plate 31 will reseal the circular hole 11. At this point, with a little more force to overcome the attraction between the second magnet 35 and the metal plate 47, the barrel-shaped container 41 can be removed.
