Problems solved by technology

In this case, however, the estimated temperature suffers from serious errors since temperature variations are not factored in
In addition, since each parameter is specified by an off-line method, the characteristics of each device of the refrigerator are not considered
[0009] In addition, since the estimated temperature is used as the input data of the fuzzy controller, it is necessary to estimate the temperature accurately, but it is difficult to achieve accurate control due to the above problems

Embodiment Construction

[0054] According to the present invention, the working state of the compressor and the cooling fan is used as the fuzzy adaptive model of the input value to establish the temperature model at the right wall 1 / 3 height and the left wall 3 / 4 height of the refrigerating room, these two places Equipped with temperature sensors respectively. After the model is established, the temperature imbalance caused by putting new food in the refrigerator is measured by the temperature difference between the measured temperature of the temperature sensor and the inference data from the fuzzy model, so as to control the blowing from the cold air channel and the cold air discharge control blade The cold air discharge direction and the total amount of cold air in the refrigerator. Therefore, the cold air is quickly and evenly distributed to reach a preset inner temperature in the refrigerating chamber. Especially, when a temperature imbalance occurs in the refrigerating chamber due to new food ...

Abstract

A temperature controlling apparatus adopting a fuzzy adaptation model and a method using the same are provided, in which temperatures of a plurality of positions of a refrigeration compartment are estimated in order to rapidly reach temperature equilibrium of the refrigeration compartment, by considering the operation states of a compressor and a cooling fan which directly affect the temperature of the refrigeration compartment. The temperature controlling apparatus includes: a cool air discharge direction controller for controlling the rotation angle of a cool air discharge control blade; and a fuzzy inference unit for inferring peripheral temperatures of temperature sensors by taking the operational states of the cooling fan and the compressor as inputs, in order to provide the cool air discharge direction controller with information with respect to the static angle of the blades of the cool air discharge control blade.

Description

technical field [0001] The present invention relates to a temperature control device and method using fuzzy reasoning, in particular to a temperature control device and method using a fuzzy adaptive model, wherein in order to quickly achieve temperature balance in the refrigerator, the device estimates The temperature of multiple locations and reflects the operating status of the compressor and cooling fans that directly affect the temperature of the refrigerator compartment. Background technique [0002] Usually, such as figure 1 As shown, the refrigerator includes a main body 4 , a freezer door 6 and a freezer door 7 . Here the main body 4 with the thermal insulation structure has a freezer compartment 2 and a refrigerator compartment 3 which are separated by a partition 1 . The main body 4 includes a shell 4a for forming a general frame, a liner 4b is provided inside the shell 4a, and a foam member 4c is filled between the shell 4a and the liner 4b. [0003] A compress...
