In the following specific embodiments, the refrigerator 100 is a T-type four-door single-system refrigerator, the refrigerating chamber 1 is located at the upper part of the refrigerator 100, the freezing chamber 2 is located at the left side of the lower part of the refrigerator 100, the temperature-changing chamber 3 is arranged at the right side of the lower part of the refrigerator 100, and the temperature-changing chamber 3 and the freezing chamber 2 are arranged in parallel left and right to reasonably allocate the storage space of the refrigerator 100. In addition, the freezing return air inlet 22 is arranged at the bottom of the freezing chamber 2, and the variable temperature return air inlet 32 is arranged at the bottom of the variable temperature chamber 3. The refrigerator 100 of the present invention may have another layout, as long as it has the temperature-changing chamber 3, the freezing chamber 2, and the refrigerating chamber 1.
Specifically, as shown in fig. 1 to 6, the freezing air inlets 21 are three and located at the upper portion, the middle portion and the lower portion of the freezing chamber 2 to uniformly exhaust air; similarly, the temperature-variable air inlets 31 are three and are located at the upper part, the middle part and the lower part of the temperature-variable chamber 3 to uniformly exhaust air.
Further, the refrigeration system 110 includes: the evaporator chamber 4 is provided with an evaporator 41 and a fan 42, the evaporator chamber 4 comprises an air outlet end 43 and an air inlet end 44, and the fan 42 is arranged close to the air outlet end 43; an air supply duct 5, which is communicated with the air outlet end 43 and includes a freezing air supply duct 51 for supplying cold air to the freezing chamber 2, a refrigerating air supply duct 52 for supplying cold air to the refrigerating chamber 1, and a variable temperature air supply duct 53 for supplying cold air to the variable temperature chamber 3; a return air duct (not shown) including a freezing return air duct (not shown) communicating the freezing return air inlet 22 with the air inlet end 44 and a variable temperature return air duct (not shown) communicating the variable temperature return air inlet 32 with the air inlet end 44; and the pressure balancing piece 6 is arranged close to the variable-temperature air return opening 32, and when the variable-temperature chamber 3 finishes refrigerating, the pressure balancing piece 6 works to balance the air pressure in the variable-temperature chamber 3. Specifically, the fan 42 is located at the rear side of the freezing chamber 2.
When the refrigerator 100 starts to refrigerate, the air flow circulation mode is as follows: the cold air cooled by the evaporator 41 flows from the air outlet end 43 along the four air supply ducts 5 under the action of the fan 42, and flows to the refrigerating chamber 1, the freezing chamber 2 and the temperature changing chamber 3 respectively; under the action of forced convection of air driven by the fan 42, the cold air flowing to each compartment flows back to the air inlet end 44 from the lowest freezing air return opening 22 and the variable temperature air return opening 32 along the air return duct, and is cooled by the evaporator 41 for the next circulation.
The structure of the present invention will be further illustrated by the following four specific examples:
as shown in fig. 1-2, in the first embodiment of the present invention, the pressure balance member 6 is a balance air duct 61 extending from the variable temperature return air inlet 32 to blow cold air to the variable temperature return air inlet 32 along the balance air duct 61, and this is equivalent to that the air in the variable temperature chamber 3 from which the air is returned from the variable temperature return air inlet 32 is changed into the cold air blown from the balance air duct 61, so that the pressure inside the variable temperature chamber 3 is not affected. Moreover, the balance air duct 61 extending from the variable temperature return air inlet 32 does not affect the temperature of the variable temperature chamber 3.
In addition, a balance air door 611 is arranged in the balance air duct 61; the variable temperature air supply duct 53 is provided with a variable temperature air door 531 near the variable temperature air inlet 31. After the temperature change chamber 3 finishes refrigerating, the temperature change air door 531 is closed, and the balance air door 611 is opened. The balance air duct 61 is in communication with the air supply duct 5, and specifically, in the present embodiment, the balance air duct 61 is in communication with the variable temperature air supply duct 53. Specifically, one end of the balance air duct 61, which is communicated with the variable temperature air supply duct 53, is located between the variable temperature damper 531 and the fan 42 and is close to the fan 42.
Specifically, in this embodiment, the balance air door 611 is disposed at one end of the balance air duct 61, which is communicated with the variable temperature air supply duct 53, and of course, the balance air door 611 is disposed at other positions in the balance air duct 61, which can also achieve the purpose of the present invention.
It should be noted that, after the temperature-variable chamber 3 finishes refrigerating, the negative pressure near the temperature-variable return air inlet 32 is the maximum because the temperature-variable return air inlet continues returning air; the amount of cold air blown out from the periphery of the fan 42 is the largest, and the pressure is the largest, and the cold air is blown into the variable-temperature air return inlet 32 along the variable-temperature air supply duct 53 to the balance air duct 61 to neutralize the negative pressure.
As shown in fig. 3, in the second embodiment of the present invention, the present embodiment is different from the first embodiment in that the balance duct 61 is communicated with the refrigerating air supply duct 52; in addition, the refrigerating air supply duct 52 is provided with a first air opening 521 and a second air opening 522 which are parallel to each other, the first air opening 521 is communicated with the refrigerating air inlet, and a refrigerating air door 523 is arranged near the first air opening 521; the second air opening 522 is communicated with the balance air duct 61, and the balance air door 611 is arranged close to the second air opening 522.

As shown in fig. 4, in the third embodiment of the present invention, the present embodiment is different from the first embodiment in that the balance duct 61 communicates with the freezing chamber 2; specifically, when the variable temperature air door 531 is closed, the amount of cold air entering the freezing chamber 2 is increased, the amount of return air is unchanged, at this time, the freezing chamber 2 is at a positive pressure, the variable temperature chamber 3 is at a negative pressure, and the cold air is blown into the variable temperature return air inlet 32 along the balance air duct 61 to neutralize the negative pressure. In addition, the balance damper 611 is disposed at one end of the balance air duct 61 communicating with the freezing chamber 2. Of course, the balance damper 611 may be disposed at other positions in the balance duct 61 to achieve the object of the present invention.
As shown in fig. 5-6, in the fourth embodiment of the present invention, the difference between this embodiment and the first embodiment is that the original pressure balancing member 6 is changed from the balance air duct 61 to the air inlet blocking piece 62 and the air return blocking piece 63, and the power assembly (not shown) for driving the air inlet blocking piece 62 and the air return blocking piece 63, that is, the original variable temperature air door 531 is changed to the linkage air door for simultaneously controlling the variable temperature air inlet 31 and the variable temperature air return inlet 32.

Specifically, three air inlet blocking pieces 62 are matched with the variable temperature air inlet 31 and are fixed with the second rack 66.
As shown in fig. 5, in this embodiment, the air inlet blocking piece 62 is disposed at a lower side of the variable temperature air inlet 31, and the return air blocking piece 63 is disposed at an upper side of the variable temperature return air inlet 32. The gear 64 is arranged between the first rack 65 and the second rack 66, when the temperature-changing chamber 3 needs to be refrigerated, the motor is started to drive the gear 64 to rotate clockwise, the first rack 65 engaged with the gear 64 moves upwards, and the return air blocking piece 63 moves upwards to open the temperature-changing return air inlet 32; the second rack 66 engaged with the gear 64 moves downwards, and the air inlet baffle 62 moves downwards to open the variable temperature air inlet 31; after the temperature change chamber 3 finishes refrigerating, the motor is started to drive the gear 64 to rotate anticlockwise, at the moment, the first rack 65 moves downwards, and the return air blocking piece 63 moves downwards to close the temperature change return air inlet 32; the second rack 66 moves upward, and the air inlet blocking sheet 62 moves upward to close the variable temperature air inlet 31.
In conclusion, the pressure balance piece is arranged near the variable-temperature air return opening of the single-system refrigerator to balance the negative pressure formed by continuous return air of the variable-temperature air return opening, so that the top of the variable-temperature chamber is prevented from frosting to the maximum extent; moreover, the pressure balance piece adopted in the invention has low cost, and the fresh-keeping effect of the food in the refrigerator is ensured on the basis of not increasing the energy consumption.
