Embodiment
Referring to Fig. 1 to Fig. 2, the horizontal frostless two-temperature freezer of the present embodiment, set in the refrigerator cabinet 1 first compartment 2 with
Second compartment 3, in the interlayer 5 that evaporator chamber 4 is placed between the first compartment 2 and second compartment 3 and top are connected with interlayer 5
Logical, its structure is specially：
First wind turbine 11 is placed in interlayer 5, positioned at the top of evaporator chamber 4, closes on the one of interlayer 5 in the first compartment 2
Side upper and lower end is connected by the first wind inlet channel 6, the first return airway 7 with evaporator chamber 4 respectively, in the first return air wind
The first rubber is set to obstruct air door 8 in road 7, the first rubber barrier air door 8 is turned on and off state corresponding to the first wind turbine 11
Open position or closing position are respectively at, 8 and first wind turbine 11 of the first rubber barrier air door, the first wind inlet channel in open position
6th, the first return airway 7 forms the circulation of the first ducting system wind path, for conveying cold to the first compartment 2；
Second wind turbine 13 is placed in interlayer 5, is positioned at the top of evaporator chamber 4 and positioned opposite with the first wind turbine 11,
Second compartment 3 closes on the side upper and lower end of interlayer 5 respectively by the second wind inlet channel 9, the second return airway 10 and evaporator chamber
Room 4 is connected, and sets the second rubber to obstruct air door 11 in the second return airway 10, and the second rubber barrier air door 11 corresponds to the
The state that is turned on and off of two wind turbines 13 is respectively at open position or closing position, the second rubber barrier air door 11 in open position
The circulation of the second ducting system wind path is formed with the second wind turbine 13, the second wind inlet channel 9, the second return airway 10, for second
Compartment 3 conveys cold.
In specific implementation, corresponding structure setting also includes：
The body of the first rubber barrier air door 8 is set to be kept off for the rubber barrier that one is rotatably arranged in the first return airway 7
Plate, open position is turned under the impact when the first wind turbine 11 is opened in air-flow, extensive by gravity when the first wind turbine 11 is closed
Multiple extremely closing position；Second rubber obstructs air door 11 has identical structure type with the first rubber barrier air door 8.
Above-mentioned evaporator 14 is tube-fin evaporator 14.
Axial-flow type or centrifugal fan can be selected in first wind turbine 11, the second wind turbine 13 respectively.
Specifically, the temperature regulating range of the first compartment 2 and second compartment 3 is 8-24 DEG C.
