Abstract
Description
Technical Field
[0001] The invention relates to the technical field of refrigerators, and in particular to a dual-system refrigeration refrigerator with variable temperature. Background Art
[0002] The refrigerator is one of the household appliances, mainly used to keep food, drinks, etc. at low temperatures to extend the shelf life of food and prevent bacteria growth and food spoilage. It achieves cooling through the refrigeration principle and is generally divided into two main parts: the refrigerator and the freezer. The refrigerator is an indispensable electrical product in home life. As consumers' requirements for fresh food increase, refrigerators are required to have higher configurations and more powerful functions.
[0003] Although existing refrigerators are provided with a freezer compartment, a refrigerator compartment and a vegetable and fruit compartment for users to store food, the refrigerator compartment is still used the most in daily life. Therefore, when the demand for the freezer compartment increases temporarily, users can only fill the freezer compartment with food as much as possible, or purchase a small freezer to solve the temporary freezing demand. However, if the freezer compartment is overfilled, the food may be stacked too tightly, which may cause the food to change its taste. Stacking the food too tightly may also prevent the air from flowing smoothly, and the cold air cannot be evenly distributed to each piece of food, resulting in uneven freezing of some food, affecting the freezing effect. Poor air flow may also cause unstable temperature in the freezer compartment, causing some areas to be too cold and other areas to be too hot, thereby affecting the storage quality of food and even causing food to thaw or deteriorate. Even if an additional small freezer is purchased, it will take up household space. Small freezers are usually large in size and occupy a considerable part of the floor space, affecting the cleanliness and convenience of the living environment. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the dual-system refrigeration with variable temperature refrigerator, a variable temperature chamber is added to the refrigerator compartment inside the refrigerator body through the coordinated use of the variable temperature drawer and the variable temperature component, so as to meet the customer's needs for storing physical objects in multiple temperature zones and prevent the food from smelling during storage. Through the coordinated use of the variable temperature drawer and the variable temperature component, the user can freely adjust the temperature inside the variable temperature drawer according to actual needs. For example, when refrigerated food needs to be placed, the interior of the variable temperature drawer is set to the refrigeration temperature; when frozen food needs to be placed, the interior of the variable temperature drawer is set to the freezing temperature. This can not only meet the storage needs of different foods, but also avoid waste of space and improve the utilization efficiency of the space of the refrigerator body.
[0015] 2. The dual-system refrigeration with variable temperature refrigerator can greatly increase the storage space inside the refrigerator body through the design of three partitions, three storage frames, fruit and vegetable boxes, ordinary drawers, variable temperature drawers, upper drawers and lower drawers.

[0024] Example 2 Please refer to Figure 2 , Figure 3 , Figure 8 , Fig. 9 and Fig.10The temperature-changing assembly 17 includes a temperature-changing placement plate 1701, which is arranged at the rear side of the inner cavity of the refrigerator body 1, a base 1702 is fixedly installed at the rear side of the temperature-changing placement plate 1701, a fan 1703 is arranged at the rear side of the base 1702, a protective shell 1704 is arranged at the rear side of the fan 1703, an electric damper 1705 is arranged at the rear side of the temperature-changing placement plate 1701, an air outlet 1706 is arranged at the front side of the temperature-changing placement plate 1701, and the front side of the air outlet 1706 penetrates into the interior of the temperature-changing drawer 14, and a refrigeration air duct return air outlet 1707 is provided at the bottom of the front side of the temperature-changing placement plate 1701. A connecting shaft 1708 is fixedly installed at the rear side of the base 1702, and a groove corresponding to the connecting shaft 1708 is provided on one side of the fan 1703.
[0025] During the implementation process, the fan 1703 is installed through the base 1702 and protected by the protective shell 1704. If the temperature inside the variable temperature drawer 14 needs to be adjusted, the fan 1703 will help accelerate the air flow so that the temperature inside the variable temperature drawer 14 can quickly reach the new set value, reducing the time required for temperature adjustment. The electric damper 1705 and the air outlet 1706 are used in conjunction to adjust the flow of cold air and temperature control. It adjusts the temperature inside the variable temperature drawer 14 according to the needs of food, and automatically adjusts the opening and closing of the damper to ensure that the cold air is evenly distributed and maintains a constant temperature inside the variable temperature drawer 14. For example, when refrigerated food needs to be placed, the interior of the variable temperature drawer 14 is set to the refrigeration temperature, and when frozen food needs to be placed, the interior of the variable temperature drawer 14 is set to the freezing temperature. This can not only meet the storage needs of different foods, but also avoid waste of space, thereby improving the utilization efficiency of the space of the refrigerator body 1.
[0026] Example 3 Please refer to Figure 1 , Figure 2 , Figure 3 and Fig.11 The adjustment component 18 includes a support plate 1801, which is fixedly installed on the bottom of the refrigerator body 1.

[0027] During the implementation process, when it is necessary to slightly adjust the height and inclination of the bottom support of the refrigerator body 1, turn the support knob 1805. The rotation of the support knob 1805 drives the connecting ring 1804 to rotate. The rotation of the connecting ring 1804 drives the threaded sleeve 1803 to rotate. The threaded sleeve 1803 is threadedly connected to the threaded rod 1802. When the threaded sleeve 1803 rotates, it moves toward the top, thereby slightly adjusting the height and inclination of the bottom support of the refrigerator body 1. The floor at home is often not completely flat, especially in old houses or when the ground has irregular undulations. The adjustment function of the bottom of the refrigerator body 1 can ensure that the refrigerator stands firmly and avoids tilting or shaking. By slightly adjusting the height and inclination of the bottom of the refrigerator body 1, the refrigerator body 1 can be placed stably, thereby preventing the internal components of the refrigerator body 1 from being subjected to additional pressure due to instability, thereby reducing equipment loss.
