Refrigerator and control method for temperature-changing chamber of refrigerator

Abstract

The invention relates to a refrigerator and a control method for a temperature-changing chamber of a refrigerator. The refrigerator comprises the temperature-changing chamber and a control panel for controlling the temperature of the temperature-changing chamber, wherein a cabinet liner of an evaporator is separated into an upper temperature-changing chamber and a lower refrigerating chamber by a heat-insulating separating plate; an air flue is arranged on the rear part of the temperature-changing chamber and the refrigerating chamber; the evaporator is located on the rear part of the air flue; an air door of the temperature-changing chamber and a fan are arranged in the air flue; a first heater is arranged on the heat-insulating separating plate in the temperature-changing chamber; a second heater is arranged on a position corresponding to the rear part of the temperature-changing chamber in the air flue; a temperature sensor is arranged on an inner side wall of the temperature-changing chamber; and the temperature is controlled by the temperature-changing chamber in refrigerating and heating two modes. The suitable heater and mounting position are selected by the refrigerator and an effective control method is used for realizing the adjustment for the temperature-changing chamber in a wide temperature scope under a wide weather condition, under the condition of saving power consumption, so that diverse and individual selections are supplied to users and the food storage requirement is met.

Description

Technical field [0001] The present invention is a technical field of refrigerators, which specializes in a refrigerator and its temperature -changing control method. Background technique [0002] With the development of economy and society, people's requirements for the quality and level of life are getting higher and higher.One of them is that people have become more and more strong in the diversification and personalization of food storage in home life.Correspondingly, there are more and more electronic products and refrigerators with a greenhouse on the market.There are separate greenhouse products and multiple refrigerators with a greenhouse.The technologies adopted are cold and cold.The temperature adjustment range of the turmoil generally includes multiple temperature intervals, such as from refrigeration to freezing. [0003] China Patent ZL0212660.5 announced a refrigerator's temperature change and control method. It controls the temperature control temperature by control...

AI Technical Summary

Problems solved by technology

[0003] Chinese patent ZL02126608.5 discloses a variable room and control method for a refrigerator. It controls the temperature of the variable room by controlling the damper and the fan motor. The variable room is a simple drawer, which is located in the cold room and has no connection with the cold room. It is completely independent and separated, it cannot be called a temperature-changing room in a full sense, and it cannot achieve a wide range of temperature adjustment, and because it is located in the refrigerator room, its temperature control accuracy is affected by refrigeration. At the same time, when the drawer is set to negative temperature, it will affect Bottom temperature has some effect

It only takes the closing time of the damper as the condition for whether the heating wire is turned on, and there is no condition for the heating wire to be turned off. There may be a phenomenon of alternating heating and cooling, which causes waste of energy consumption, that is, there is no obvious conversion distinction between heating and cooling.

[0005] To sum up, in the prior art, the variable greenhouse temperature is mostly realized by controlling dampers, fans and heating wires, but none of them clearly distinguishes the cooling mode from the heating mode, and there is a problem of alternating cooling and heating, which affects food storage and causes Increased energy consumption; and large temperature fluctuations in greenhouses, which affect the quality of food storage
