refrigerator

Abstract

The invention provides a refrigerator. The refrigerator includes a box body defining a refrigerating compartment, a variable temperature compartment and a freezing compartment, and a refrigerating door body, a variable temperature door body and a freezing compartment for opening and closing the access openings of the refrigerating compartment, the variable temperature compartment and the freezing compartment respectively. door body. The refrigerator also includes an ultrasonic generating module and a thawing area with an opening on the top side. An ultrasonic vibrator arranged to be electrically connected to the ultrasonic generating module is arranged in the thawing area to generate ultrasonic waves of corresponding frequency and power in the thawing area according to the ultrasonic signal, and defrost to be processed. The thawing area is set in the temperature-changing compartment. Compared with setting the thawing device in other compartments, it has less influence on the temperature of the storage space outside the thawing area in the compartment, and avoids the air temperature in the storage space outside the thawing area. large fluctuations.

Description

technical field [0001] The invention relates to the field of food thawing, in particular to a refrigerator with a thawing function. Background technique [0002] Food cryopreservation is an efficient food preservation method, which can maintain high-quality food quality without polluting food, and is widely used in daily life. However, Chinese families generally require thawing to an easy-to-cut state (about -5°C) when cooking. How to make the temperature of the food to be thawed quickly and evenly rise from a frozen state (about-18°C) to an easy-to-cut state has always been a problem for people. issues of widespread concern. [0003] However, in the prior art, the thawing of air thawing and water thawing takes a long time, is easily contaminated by microorganisms and bacteria, loses more nutrients, has a large temperature difference between inside and outside, and is difficult to control the progress of thawing; heating wires and heating tubes thaw quickly, but the juice i...

Problems solved by technology

[0003]However, in the prior art, the thawing of air thawing and water thawing takes a long time, is easily contaminated by microorganisms and bacteria, loses more nutrients, and has a large temperature difference between inside and outside and is difficult to control The progress of thawing; the heating wire and heating tube thaw quickly, but the juice loss is serious and the thawing is uneven. Usually, the outside of the food has been heated thoroughly, and the inside is still in a frozen state; the thawing speed of microwave thawing is fast, and it is not easy to be polluted by microorganisms and bacteria. The loss of nutrients is less, the disadvantage is that the thawing is not uniform, and it is prone to local burnt phenomenon
