Description of drawings

Fig. 1 is a structural schematic diagram of an embodiment of the air supply structure of the present invention.

Detailed ways

The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

The air-cooled refrigerator of the present invention is a single-system air-cooled refrigerator, including a box body, a door body, an air duct, a fan, a compressor, an evaporator, a first temperature sensor, a second temperature sensor and a controller.

Referring to FIG. 1 , in one embodiment of the present invention, the cabinet includes a freezer compartment 10 and a refrigerator compartment 20 .

The door body is pivotally installed on the box body to open or close the freezing chamber 10 and the refrigerating chamber 20 .

The compressor increases the gas pressure of the refrigerant to cause liquefaction conditions. When the refrigerant flows through the condenser, it liquefies and releases heat, and then passes through the capillary tube to reduce the pressure and temperature. When it reaches the evaporator 30, it boils and vaporizes, absorbs heat, and cools the box. The evaporator 30 is located in the freezer compartment, and the cold air generated by it enters the freezer compartment 10 through the freezer air outlet.

A first tuyere 40 is provided on the dividing plate between the freezer interior and the refrigerating interior, and the first air opening 40 is connected to the refrigerating air duct 50, which is located in the refrigerating interior. The fan 60 is arranged between the evaporator 30 and the first air outlet 40 , and is used to circulate the cold air from the evaporator 30 into the refrigerating air duct 50 , and then deliver it to the refrigerating room 20 .

The first temperature sensor and the second temperature sensor are located in the box. Wherein, the first temperature sensor is used to detect the temperature of the refrigerator compartment 20 , and the second temperature sensor is used to detect the temperature of the freezer compartment 10 .

The controller is respectively connected with the compressor, the fan 60, the first temperature sensor and the second temperature sensor to control the operation of the compressor according to the temperature of each room, drive the evaporator 30 to refrigerate, and control the start and stop of the fan 60 to control the temperature of each room. The cooling capacity is distributed among the chambers to realize cooling of the freezing chamber 10 or the refrigerating chamber 20 .

The evaporator 30 is a tubular evaporator, as shown in Figure 1, the coil 301 of the evaporator 30 passes through the inner liner of the freezer, penetrates the partition between the inner liner of the freezer and the inner liner of the refrigerating room, and enters the refrigerating room The liner extends vertically around the first tuyere 40 , and is coiled into a spiral tube shape to form a refrigerating air duct 50 . The bottom of the spiral tube is on the same plane as the outlet of the first tuyere 40 , so that the spiral tube connects with the first tuyere 40 without gap. And the coiled pipe 301 is wound without gaps, forming a closed air supply space. The coiled tube 301 is a metal tube, which can easily realize the coiled structure of the spiral tube.

The spiral tube is located in the accommodation space formed by the inner liner and the cover plate 70 in the refrigerator. The cover plate 70 isolates the refrigerating air duct 50 from the storage space of the refrigerating room 20 , and plays an aesthetic role. The cover plate 70 is provided with at least one second air outlet 701 .

In yet another embodiment of the present invention, the coiled pipe 301 enters the refrigerator interior chamber (not shown) from the refrigerator interior chamber through the first tuyere 40 . In this way, there is no need to open another through hole on the partition plate for the coil pipe 301 to pass through.

The invention does not need to assemble a refrigerating air duct, but uses the coil of the evaporator to wind the air duct to send the cold air from the freezing room into the refrigerating room, and at the same time, the refrigerant in the coil boils and vaporizes to absorb heat, thereby enhancing the cooling effect of the refrigerating room.

It should be understood that although this description is described according to implementation modes, not each implementation mode only contains an independent technical solution, and this description in the description is only for clarity, and those skilled in the art should take the description as a whole, and each The technical solutions in the embodiments can also be properly combined to form other embodiments that can be understood by those skilled in the art.

The series of detailed descriptions listed above are only specific descriptions for feasible implementations of the present invention, and they are not intended to limit the protection scope of the present invention. Any equivalent implementation or implementation that does not depart from the technical spirit of the present invention All changes should be included within the protection scope of the present invention.
