When T time is up, the part to be temperature-controlled has been heated, and B is the time required to heat to the heating required temperature; when the detected temperature reaches the heating required temperature, it enters the insulation stage, and when it is detected that: when T<CX, the heating part 20 starts heating; when CX≤T<C+X, the heating part 20 maintains the current operating state; when T≥C+X, the heating part 20 stops heating; wherein, T is the temperature of the liquid in the box body 10, X is the temperature fluctuation range, and C is the preset temperature. The value range of X is generally 0℃~5℃. The insulation icon on the panel is always on and the buzzer sounds to remind the user that heating is complete.

[0074] In specific implementation, the present invention proposes a built-in refrigerator hot and cold conversion device and control method. By embedding an independent device, namely the hot and cold conversion device 1, in the refrigerator refrigeration area, the refrigerator is in a refrigeration state by default when the user has no demand. When the user has a heating demand, immediate heating or scheduled heating and insulation effects can be achieved through the corresponding function buttons on the operation panel. The user only needs to take out the items from the refrigerator and drink them directly according to the prompt after the heating is completed, making it more convenient and quick for the user to use.

[0075] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0076] The refrigerator of the present invention uses a liquid level detection member 50 disposed inside the device to detect whether the pump body 61 has added water in place, and then determines whether the heating temperature meets the heating requirement temperature based on a temperature detection member 80 disposed inside the device; using a reservation timing function, the cold-heat conversion device 1 is controlled to enter the heating stage at a preset time, and the required heating time is estimated in advance so that the food or medicine is heated just after the scheduled time; through liquid level detection and temperature detection control, an integrated design of refrigerator refrigeration and heating is achieved, making it more convenient, fast, safe and reliable for users to use. The cold-heat conversion device 1 embedded in the refrigerator compartment of the refrigerator of the present invention can realize the refrigeration and heating of food or medicine, and the heating temperature is precisely controllable, ensuring the quality of the food or medicine and reducing the heating risk of using open flames to heat food or medicine. Through a more intelligent control method, the user can use it more convenient, fast, safe and reliable.

[0077] The refrigerator of the present invention includes a refrigerator body, which has a refrigerating chamber, in which a heat-cold conversion device 1 is embedded. The heat-cold conversion device 1 includes a box body 10. The accommodating cavity 11 of the box body 10 is used to accommodate the temperature-adjusted item. When the user needs to refrigerate the temperature-adjusted item, the connecting port 12 is opened, and the cold air in the refrigerating chamber enters the accommodating cavity 11 through the connecting port 12; when the user needs to heat the temperature-adjusted item, the connecting port 12 is closed, and the cold air in the refrigerating chamber no longer enters the accommodating cavity 11 through the connecting port 12. At the same time, the heating unit 20 heats the accommodating cavity 11, thereby heating the temperature-adjusted item. The refrigerator of the present invention achieves heating of the temperature-adjusted item through the heat-cold conversion device 1, thereby solving the problem that refrigerators in the prior art cannot heat refrigerated items and are not convenient. The refrigerator integrates refrigeration and heating, greatly meeting the needs of users. Users can use it more conveniently, quickly, safely and reliably, and it also greatly improves the competitiveness of refrigerator products.
