Detailed Description

Fig. 1 is a schematic rear perspective view of a refrigerator 100 according to an embodiment of the present invention. Fig. 2 is a schematic view of a rear back panel 201 of the refrigerator 100 shown in fig. 1. The refrigerator 100 may generally include a cabinet 110, a door, and a storage container 200. The cabinet 110 defines a plurality of storage compartments therein. The storage chamber is used for storing food, a storage container 200 is arranged in the storage chamber, and a fresh-keeping space is limited in the storage container 200. The storage compartments of the embodiment of the present invention may include a refrigerating compartment 120, a first freezing compartment 130, and a second freezing compartment 140. The door body can be a plurality of, and every door body is configured to the controlled opening or the closed one storing compartment. The back plate 201 of the storage container 200 includes a condensation body part 210 and a condensation guide part 211. The condensation body 210 allows moisture in the storage container 200 to condense into water drops. The condensation guiding portion 211 is disposed on the front end surface of the condensation body 210, and has a drainage port 202 at the bottom. The utility model discloses refrigerator 100 sets the backplate 201 of storing container 200 to the structure that has condensation body portion 210 and condensation water conservancy diversion portion 211, and outlet 202 has been seted up to the bottom of condensation water conservancy diversion portion 211 for moisture in the fresh-keeping space can in time condense and discharge.

In some embodiments, the condensation guiding portion 211 has a funnel-shaped longitudinal section, and the drainage port 202 is disposed at the bottom of the funnel-shaped longitudinal section.

In some embodiments, the storage container 200 is disposed in the refrigerating compartment 120, and the refrigerating air supply opening 125 and the refrigerating air return opening 126 are disposed in the refrigerating compartment 120, and the refrigerating air return opening 126 is disposed opposite to the back plate 201 of the storage container 200. The cabinet 110 is provided with a refrigerating evaporator 123 in a refrigerating duct 124 at the rear of the refrigerating compartment 120. The refrigerating evaporator 123 is provided above the refrigerating return air inlet 126 for generating cold to be supplied to the refrigerating compartment 120. A refrigerating frost sensor 121 is also provided at the refrigerating evaporator 123. The refrigerated air duct 124 is used to provide a circulation path for cooling. In one embodiment, a refrigeration fan 122 is also disposed within the refrigeration duct 124 for delivering refrigeration to the refrigeration compartment 120 and is configured to: and the refrigerator is started again after the set time period after the cooling air supply is finished until the temperature of the refrigerated defrosting sensor 121 is greater than or equal to the preset temperature threshold value.

The refrigeration fan 122 is part of the refrigeration system of the refrigeration compartment 120. Specifically, the refrigeration system may be a compression refrigeration system including a compressor, a condenser, a throttling device, an evaporator, and the like. A freezing fan 132, a freezing evaporator 133, and a freezing air duct 134 are provided corresponding to the first freezing compartment 130 and the second freezing compartment 140. The casing 110 also has a compressor bin. The compressor may be disposed within the compressor bin. The compression refrigeration system enables the refrigeration evaporator 123 to release cold energy through refrigerant compression circulation, and the working principle is as follows: the compressor is driven by a motor to rotate continuously as power of a refrigeration cycle, and compresses low-temperature and low-pressure refrigerant vapor to a high-temperature and high-pressure state. The condenser is a heat exchange device, and takes away heat of high-temperature and high-pressure refrigeration steam from the compressor by utilizing an environment cooling refrigerant, so that the high-temperature and high-pressure refrigeration steam is cooled and condensed into high-pressure and normal-temperature refrigeration liquid. The refrigerant liquid with high pressure and normal temperature passes through the throttling device to obtain low-temperature and low-pressure refrigerant, and then is sent into the refrigeration evaporator 123 for heat absorption and evaporation. The refrigeration evaporator 123 is used as another heat exchange device, and the throttled low-temperature and low-pressure refrigerant liquid is evaporated in the refrigeration evaporator to be changed into vapor, so that ambient heat is absorbed, the ambient temperature is reduced, and the purpose of refrigeration is achieved.

Fig. 3 is a schematic diagram of a cool air cycle of the refrigerator 100 shown in fig. 1 when the refrigerating fan 122 is operated. Fig. 4 is a schematic diagram of a cool air flow direction of the refrigerator 100 shown in fig. 1 when the refrigerating fan 122 is stopped. When the refrigerating compartment 120 is cooled, cool air from the refrigerating evaporator 123 is blown into the refrigerating compartment 120 through the refrigerating air blowing port 125, exchanges heat in the refrigerating compartment 120, and returns to the refrigerating evaporator 123 through the refrigerating air return port 126. When the refrigerating compartment 120 reaches the shutdown point, the refrigerating fan 122 stops operating, and the refrigerating evaporator 123 is still at about-15 to-20 ℃, and due to the fact that the density of cold air is high, cold air automatically sinks and flows out from the refrigerating return air inlet 126, so that the temperature of the back plate 201 of the storage container 200 is lower than that of other plates by more than 1 ℃. On the one hand, since the temperature of the rear back panel 201 is low, the air with high humidity automatically condenses on the rear back panel 201, flows to the drain port 202 and is discharged out of the storage container 200. On the other hand, the back board 201 is easy to freeze at 0 ℃ or lower, which causes the fruits and vegetables near the back board 201 to be frozen and rotten, and causes complaints of users. Therefore, the refrigerator 100 according to the embodiment of the present invention can prevent the refrigerating fan 122 from being configured to operate for the second time. In one embodiment, when the compartment temperature of the refrigerating compartment 120 reaches the shutdown point temperature, the refrigerating fan 122 is stopped, and after 4min, the refrigerating fan 122 starts to operate again until the temperature of the refrigerating defrosting sensor 121 is greater than or equal to 1 ℃.

In some embodiments, the refrigerator 100 further comprises: and a condensation drain pipe 203 connected to the drain port 202, so that the condensed water drops are discharged out of the storage container 200 through the drain port 202 and the condensation drain pipe 203.

In one embodiment, the condensation drain pipe 203 has a U-shaped bent section 231 to ensure the sealing of the fresh food space and prevent external air from entering the fresh food space through the drain port 202.

In some embodiments, an end of the condensation drain pipe 203 is connected to the defrosting drain pipe 150 of the refrigerator 100; an evaporation pan 160 is provided below the end of the defrosting drain pipe 150. This allows the draining of the water droplets to be achieved by means of the existing evaporation pan 160. A three-way valve 204 is provided at the junction of the dew condensation drain pipe 203 and the defrosting drain pipe 150.

The superconducting plate is formed by adding an element for improving the thermal conductivity of a plate-like structure, such as a superconducting disk, to a multilayer plate-like structure, and has high thermal conductivity.

In one embodiment, the condensation guide 211 is an aluminum plate or a superconducting plate. That is, the back plate 201 may be an aluminum plate or a superconducting plate as a whole, and only the condensation body portion 210 may be an aluminum plate or a superconducting plate. The condensation body 210 and the condensation guiding part 211 may be an integrated structure or a split structure. The front panel, side panels, and bottom panel of the storage container 200 are generally made of plastic.
