The invention will be further explained with reference to the drawings.

An embodiment of the present invention provides a thawing chamber structure of a refrigerator, including:

an air inlet 11 and an air outlet 12 are respectively arranged at two sides of the unfreezing compartment 1;

the air inlet duct 2 is communicated with the air inlet 11 and comprises a hot air branch 21 and a cold air branch 22, a first control valve 4 is arranged at the intersection point of the hot air branch 21 and the cold air branch 22, and the two are respectively communicated with a chamber where the condenser is located and a refrigerating chamber;

the first control valve 4 can selectively conduct the hot air branch 21 or the cold air branch 22 to guide the thawing hot air emitted from the condenser or the fresh-keeping cold air in the cold storage compartment into the thawing compartment 1.

Specifically, as shown in fig. 1 and fig. 2 of the accompanying drawings, the thawing compartment 1 in the thawing compartment structure of the present invention is independent of the refrigerating compartment and the freezing compartment in the refrigerator, and the thawing compartment 1 has an air inlet 11 and an air outlet 12, respectively, to achieve thawing and freshness keeping of food in the thawing compartment 1 by air flow.

In the thawing mode, the first control valve 4 turns on the hot air branch 21 and turns off the cold air branch 22, and the hot air branch 21 guides the waste heat generated by the condenser to the thawing compartment 1 to thaw the frozen food placed in the thawing compartment 1. In particular, when the condenser of the refrigerator works, a large amount of heat is released due to liquefaction of a refrigerating medium, the heat needs to be exhausted out of the refrigerator in general, and the invention utilizes the part of waste heat to thaw food. The heat generated by the condenser heats the surrounding air, and the hot air enters the thawing compartment 1 through the hot air branch 21 to thaw food.

Under the mode of keeping fresh, first control valve 4 switches on cold wind branch 22 and closes hot-blast branch 21, and the food at this moment has already unfreezed and has accomplished, in order to prevent food after the unfreezing from rotting, introduces the cold wind in the refrigerator cold-storage compartment into unfreezing compartment 1 through cold wind branch 22 to carry out low temperature fresh-keeping to food.

In addition, according to user's user demand, can direct control first control valve 4 switch on cold wind branch road 22 and close hot-blast branch road 21, and then will unfreeze room 1 and regard as cold-stored room, at this moment, can directly place food and carry out low temperature fresh-keeping in unfreezing room 1.

According to the unfreezing chamber structure, waste heat of the condenser is used for heating and unfreezing food, and original cold air in the cold storage chamber is used for keeping the food fresh, so that the condenser is favorable for heat dissipation, an additional unfreezing device is not required, and the energy consumption of a refrigerator is saved; and can keep food fresh after thawing, avoid the food that artificially forgets after thawing to lead to food rotten.

Preferably, a temperature sensor is arranged in the thawing compartment 1, and the temperature sensor is arranged at the bottom of the thawing compartment 1.

Specifically, the temperature sensor is used for sensing the real-time temperature of the food in the thawing compartment 1 to judge whether the food is thawed. When food thawing is finished, the temperature sensor feeds back a signal to a controller of the refrigerator, and the controller controls the first control valve 4 to switch to a fresh-keeping mode of the thawing compartment 1, namely, the cold air branch 22 is switched on and the hot air branch 21 is switched off. The temperature sensor is arranged at the bottom of the thawing compartment 1 and can be closer to food or contact with the food, so that the real-time temperature of the food can be more accurately detected.

In one embodiment, further comprising:

the air outlet channel 3 is communicated with the air outlet 12 and comprises an outer discharge branch 31 and a circulation branch 32, and a second control valve 5 is arranged at the junction of the outer discharge branch 31 and the circulation branch 32;

the thawing hot air entering the thawing compartment 1 is discharged outside through the discharge branch 31, and the fresh-keeping cold air entering the thawing compartment 1 is discharged to the cavity where the evaporator is located through the circulation branch 32.

Specifically, as shown in fig. 2 of the drawings, the external discharging branch 31 is used for discharging the hot thawing air in the thawing compartment 1, and since the food is heated and thawed by the hot thawing air, and the food carries part of the moisture generated by thawing the food, the hot thawing air entering the thawing compartment 1 cannot circulate in the refrigerator, and needs to be discharged to the outside of the refrigerator. The fresh-keeping cold air for keeping the food in the thawing compartment 1 can be discharged into the refrigerator for internal circulation, namely, the fresh-keeping cold air for keeping the food in the thawing compartment 1 is conveyed to the evaporator through the circulation branch 32, and is input again for keeping the food fresh at a low temperature after heat exchange and temperature reduction, and the circulation is carried out.

In addition, as the selective conduction of the outer discharge branch 31 and the circulation branch 32 is realized through the second control valve 5, and the branch switching of the air outlet channel 3 and the air inlet channel 2 needs to be kept synchronous, the second control valve 5 and the first control valve 4 can be set to be linked to keep the synchronization.

Preferably, the outer discharge branch 31 is directly communicated with the external environment, or the outer discharge branch 31 is communicated with the external environment through a condensation water collecting device.

Specifically, the hot wind discharged from the outward discharging branch 31 carries the moisture produced by thawing, so that the hot wind can be directly discharged to the external environment or discharged to the external environment after being removed by the condensation water collecting device according to specific conditions or user requirements.

Further, the outer discharge branch 31 may be provided with two discharge ports, one of the discharge ports is directly communicated with the external environment, the other discharge port is connected with the condensation water collecting device, and a control valve is arranged between the two discharge ports to realize selective conduction, so as to adapt to different use requirements.

In one embodiment, a wind guiding structure 6 is arranged at the connection position of the hot wind branch 21 and the cavity where the condenser is located, and the wind guiding structure 6 is provided with a horn-shaped wind guiding opening 61.

Specifically, as shown in fig. 3, the air guiding structure 6 is disposed corresponding to a condenser of the refrigerator, and is used for guiding air heated by heat of the condenser into the hot air branch 21, and the trumpet-shaped air guiding opening 61 is beneficial to guiding hot air into the hot air branch 21.

Preferably, an air guiding fan is arranged at the air guiding opening 61.

Specifically, since the internal structure of the refrigerator is compact, the length of the hot air branch 21 is very limited, and when the air guide fan is not provided, the hot air can spontaneously enter the hot air branch 21 through the air guide opening 61 due to the pressure difference caused by the temperature, but the spontaneous circulation speed of the hot air is slow, the direction is poor, the flow rate of the defrosting hot air in the hot air branch 21 is small, and the defrosting efficiency of the corresponding defrosting compartment 1 is low.

Therefore, by providing an air guide fan (not shown in the drawings) to forcibly and rapidly guide the hot air near the condenser into the hot air branch passage 21, the flow rate of the thawing hot air can be greatly increased, thereby improving the thawing efficiency. The air guide fan corresponds to the thawing mode and operates in the thawing mode.

Furthermore, based on the air guide fan, the unfreezing chamber structure further has a normal temperature mode. In the normal temperature mode, the first control valve 4 conducts the hot air branch 21, and the second control party conducts the outward discharge branch 31, but the air guide fan does not operate. At this time, a normal temperature environment is basically maintained in the thawing compartment 1, so that the thawing compartment 1 can be used as a food storage room and a light shielding room in the normal temperature environment to store some foods which do not need to be frozen or kept fresh under the condition of no food thawing or fresh-keeping requirements. Therefore, the utilization rate of the internal space of the refrigerator can be improved, and the situation that the unfreezing compartment 1 is idle to cause space waste is avoided. Preferably, the air guiding structure 6 is arranged above the condenser.

Specifically, because the density of hot air is little, it can spontaneous vertical upwards removal to set up wind-guiding structure in the top of the condenser, be more favorable to hot air to pass through wind-guiding structure and get into hot-blast branch road.

In one embodiment, a heat storage device is disposed at the wind guiding structure 6.

Specifically, due to the refrigeration principle of the refrigerator, a state that the condenser and the evaporator work simultaneously exists, and at the moment, the condenser releases heat and the evaporator absorbs heat, so that heat near the condenser is insufficient, and the defrosting temperature requirement cannot be completely met. The heat generated by the condenser is stored by means of a heat storage device (not shown in the drawings) arranged, and in the event of insufficient heat, the heat released by the heat storage device ensures the amount of heat required for thawing the food in the thawing compartment 1.

In one embodiment, the top wall of the thawing compartment 1 has an air inlet chamber 7 communicating with the air inlet 11, the air inlet chamber 7 having a plurality of outlets evenly distributed and facing the interior of the thawing compartment 1.

Specifically, as shown in fig. 1 of the accompanying drawings, thawing hot air or fresh-keeping cold air entering the thawing compartment 1 through the air inlet 11 firstly enters the air inlet cavity 7, and then is uniformly blown to food from above through an outlet on the air inlet cavity 7, so that the thawing and fresh-keeping uniformity can be improved, and the thawing and fresh-keeping effects can be ensured.

The embodiment of the invention also provides a refrigerator which comprises the unfreezing chamber structure and further has all the technical effects of the unfreezing chamber structure.
