Upper-refrigerating and lower-freezing electric control direct-cooling micro-frost refrigerator and assembling method thereof

Abstract

The invention discloses an upper-refrigerating and lower-freezing electric control direct-cooling micro-frost refrigerator and an assembling method thereof, and relates to the field of micro-frost refrigerators. The refrigerator comprises a refrigerating chamber and a freezing chamber, wherein the refrigerating chamber is arranged on the upper part of the refrigerator, the freezing chamber is positioned below the refrigerating chamber; and a refrigerating chamber temperature sensing unit, a controller and a refrigerating evaporator are arranged on the inner wall of the refrigerating chamber, the refrigerating chamber temperature sensing unit comprises a defrosting sensor, an environment sensor and a temperature sensor, the defrosting sensor is fixed on a refrigerating evaporator pipeline through an aluminum foil adhesive tape, the environment sensor is arranged in a box shell pre-buried box of the refrigerator, and the temperature sensor is arranged in a refrigerating chamber box container. According to the refrigerator, the problems of an exciting electric control direct-cooling refrigerator that the working efficiency of energy consumption, temperature and freezing chamber frosting is low, the temperature of the refrigerating chamber and the freezing chamber is not uniform, the temperature of the refrigerating chamber cannot be accurately controlled, the harsh requirements ofdifferent food materials on the temperature cannot be met, frosting in the freezing chamber cannot be effectively solved, and the user experience degree is poor are solved.

Description

technical field [0001] The invention belongs to the field of micro-frost refrigerators, in particular to an electronically controlled direct-cooling micro-frost refrigerator with top storage and bottom freezing and an assembly method thereof. Background technique [0002] At present, in the direct-cooling refrigerators exported on the market, the evaporator of the freezer compartment is mostly fixed inside the box, and traditional mechanical temperature control is adopted, which has the following problems: 1. Serious frosting on the surface of the silk tube or aluminum plate evaporator; 2. .The refrigerating evaporator is large in size and cannot be dismantled and moved, resulting in a waste of space in the freezer; 3. The product requires internal welding of the box, and the manufacturability is poor; 4. The temperature control accuracy is poor; 5. The control parameters of the mechanical thermostat drift greatly, resulting in refrigeration and freezing The large difference...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an electronically controlled direct-cooling micro-frost refrigerator with upper storage and lower freezing and its assembly method. The invention adopts the coiling process, cooperates with the electronic control defrosting system, and can reduce the frosting phenomenon in the freezing chamber by working with the heating wire , so as to improve the user experience; to solve the problem that the evaporator of the traditional top-bottom direct-cooling refrigerator occupies a large space and cannot be moved, and the space utilization rate of the user is poor during use. The evaporator of the new structure freezer adopts coiled tubes and built-in glass shelves The accessories can be disassembled, and the space utilization is improved; three sensors are used to replace the traditional mechanical temperature control, which solves the problems of low energy consumption, temperature, frosting in the freezer, and uneven temperature in the freezer and freezer of the existing electric-controlled direct-cooling refrigerators. The refrigerator room cannot precisely control the temperature, and cannot meet the stringent temperature requirements of different ingredients. Frosting in the freezer room cannot be effectively solved, and the user experience is poor.
