Refrigerator

Abstract

The invention provides a refrigerator. The refrigerator comprises a refrigerating chamber and a freezing chamber, wherein the refrigerating chamber is provided with a refrigerating heater and a refrigerating temperature control switch; the freezing chamber is provided with a freezing temperature control switch; the refrigeration temperature control switch, the freezing temperature control switch and the refrigeration heater are connected in series to form a temperature compensation electric loop; when the temperature of the refrigerating chamber is lower than the second refrigerating temperature and the temperature of the freezing chamber is higher than the first freezing temperature, the refrigerating temperature control switch and the freezing temperature control switch are both closed, and the refrigerating heater heats; according to the refrigerator, normal-temperature food placed in the freezing chamber can be sensed in time, and rapid refrigeration and cooling can be achieved; when the freezing chamber is rapidly cooled, the refrigerating chamber is in the state that the refrigerating capacity and the heating capacity are basically equivalent, the temperature of the refrigerating chamber is basically kept constant, and the situation that the temperature of the refrigerating chamber is too low or negative due to long-time refrigeration required by freezing is avoided; and on the other hand, the situation that refrigeration is slow due to heating of the refrigeration heater when the refrigeration chamber needs refrigeration can be avoided, the fresh-keeping quality of food in the refrigeration chamber is guaranteed, and the purpose of saving energy is achieved.

Description

technical field [0001] The invention belongs to the technical field of household refrigerators, and in particular relates to a refrigerator. Background technique [0002] In recent years, with the continuous improvement of people's living standards, household appliances have gradually moved towards the development direction of diversified functions, high quality and high cost performance. At present, the mechanical direct-cooling refrigerating and freezing refrigerators in the middle and low-end market have relatively single functions. The main control principle is: using a mechanical thermostat to extend the temperature-sensing head (or temperature-sensing package) to the evaporator of the refrigerator, When the monitored temperature reaches the corresponding preset start-up (or stop) temperature value, the refrigerator running circuit is connected (or disconnected) to realize the start-stop control of the refrigerator compressor, thereby realizing the refrigeration cycle o...

AI Technical Summary

Problems solved by technology

[0003] Since this type of mechanical direct cooling refrigerator freezer controls the start and stop of the compressor through a single refrigeration temperature sensing head (or temperature sensing package), when the temperature of the freezing chamber is high (such as the user opens the door and puts food at room temperature), the refrigeration feeling The temperature head cannot be sensed, causing the food newly put into the freezer to not cool down quickly in time, which may affect the freshness and quality of the food
