Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] Such as Figure 1 to Figure 8 As shown, the refrigerator 100 of the present invention includes a box body 2, an air duct assembly 1, and a refrigeration system.
[0026] The box body 2 is provided with a first compartment 201 and a second compartment 202 , and the set temperature in the second compartment 202 is lower than the set temperature in the first compartment 201 . The first compartment 201 includes a first storage part and a first door. The second compartment 202 includes a second storage portion 22 and a second door body 21 .
[0027] The air duct assembly 1 includes a first air duct for delivering cold air to the first compartment 201, a second air duct for transporting cold air to the second compartment 202, a first return air...

The invention provides a refrigerator which comprises a box body, an air flue assembly and a refrigerating system, wherein a first room and a second room are arranged in the box body; the air flue assembly comprises a first air flue and a second air flue, and the first air flue communicates to the second air flue; the refrigerating system comprises an evaporator and a blowing fan mounted in the second air flue; the blowing fan is mounted in the first air flue. The refrigerator also comprises a first control unit which comprises a first control circuit and a first operating unit; the first control circuit accelerates the rotating speed of the blowing fan according to a signal of the first operating unit so as to increase the air pressure in the first room, reduce the inner and outer air pressure difference and reduce the door opening force; or the blowing fan is mounted in the second air flue. The refrigerator also comprises a second control unit which comprises a second control circuitand a second operating unit. The second control circuit controls the blowing fan to reverse or accelerates the rotating speed of the blowing fan according to a signal of the second operating unit soas to increase the air pressure in the second room, reduce the inner and outer air pressure difference and reduce the door opening force.
Description
technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator which solves the air pressure difference inside and outside the box. Background technique [0002] After the existing refrigerator cools down the internal space for a certain period of time after the door is closed, and the internal temperature of the refrigerator tends to be stable, the internal air pressure is lower than the external air pressure, so that there is an air pressure difference between the inside and outside of the refrigerator, and the user needs to apply a large pressure when opening the door. It can only be opened with a strong force, or even unable to open, which will affect the user's use. [0003] In view of this, it is necessary to provide an improved refrigerator to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a refrigerator, which avoids the difficulty of opening the ...
