Moreover, repeated reference numerals or designations may be used in various embodiments. These iterations are merely for simplicity and clarity of describing the present invention, and are not intended to represent any correlation between the different embodiments or structures discussed.
As shown in fig. 1, the utility model provides a refrigerator, which comprises a refrigeration system, wherein the refrigeration system is arranged in the refrigerator and circulates with a refrigerant; the refrigerating system comprises a condenser, a capillary tube, an evaporator and a compressor which are communicated with each other. Of course, the refrigeration system further comprises a refrigeration fan and a refrigeration air duct which are communicated with the evaporator 1, so that the refrigeration capacity of the evaporator 1 is transferred to the cold storage chamber and the freezing chamber.
In particular, the present invention relates to a refrigerator comprising an evaporator chamber 10 for accommodating the evaporator 1 and a defrosting system disposed in the evaporator chamber 10, wherein the defrosting system is independent of the refrigerating system. Specifically, the defrosting system includes:
a heating device 2 disposed adjacent to the evaporator 1;
the fan 3 is arranged far away from the heating device 2;
and the air duct 4 surrounds the evaporator 1 and is communicated with the heating device 2 and the fan 3, and a plurality of air ports facing the evaporator 1 are formed in the air duct 4.
Thus, the air duct 4 can communicate the heating device 2 and the fan 3, so that the fan 3 can blow the heat generated by the heating device 2 in the evaporator chamber 10, and the air duct 4 is arranged around the evaporator 1, so that the evaporator 1 is uniformly heated, the temperature of the whole evaporator 1 is increased, defrosting is facilitated, and incomplete defrosting caused by local heating is prevented. Moreover, since the integral defrosting system is located in the evaporator chamber 10, heat can be prevented from being dissipated to the outside of the evaporator chamber 10, so that the refrigerating effect of the refrigerator can be prevented from being affected.
The heating device 2 is a heating wire and is positioned below the evaporator 1. The evaporator 1 is flat and extends in the vertical direction, and the heating device 2 extends in the transverse direction of the evaporator 1 and has a length less than that of the evaporator 1 in the transverse direction. Due to the arrangement of the fan 3 and the air duct 4, the length of the heating device 2 is not suitable to be too long. In the present embodiment, the heating device 2 is provided below the evaporator 1, and the object of the present invention can be achieved if the heating device 2 is provided above the evaporator 1 or at another position such as a side edge.
The fan 3 is far away from the heating device 2, and if the fan 3 is too close to the heating device 2, the circulation of hot air is not completely stable enough. Therefore, in the present embodiment, the heating device 2 is disposed below the evaporator 1, and thus the fan 3 is disposed close to the upper side of the evaporator 1, so that heat is uniformly and rapidly transferred to various positions of the evaporator 1. Specifically, fan 3 sets up in the top position of 1 side of evaporimeter, wind channel 4 is including just to fan 3's exhaust duct 41, exhaust duct 41 follows the side longitudinal extension of evaporimeter 1. Moreover, the length of the air outlet duct 41 is not longer than the length of the side edge of the evaporator 1, and the extension length of the air outlet duct 41 on the side edge of the evaporator 1 is not more than 4/5 of the length of the side edge of the evaporator 1.
As shown in fig. 1, the defrosting system includes a first air pipe 51 communicated with one end of the air outlet duct 41 far away from the blower 3 and extending to the outside of the evaporator chamber 10, and the defrosting system further includes a first one-way valve 61 arranged on the first air pipe 51, wherein the first one-way valve 61 only allows the first air pipe 51 to exhaust air outwards. The first air duct 51 may be in communication with other compartments or devices that are frosting and require defrosting, thereby also assisting other compartments or devices in defrosting while defrosting in the evaporator chamber 10. And, the first check valve 61 allows only the first air pipe 51 to blow air outward, so that external air or cold can be prevented from being transferred into the evaporator chamber 10 through the first check valve 61, thereby ensuring uniform temperature and heat dissipation efficiency in the evaporator chamber 10.
The defrosting system further comprises an air return duct 42, wherein the air return duct 42 is distributed in an L shape and is arranged on the other side of the evaporator 1. The air return duct 42 includes a first portion 421 extending in the horizontal direction and a second portion 422 extending in the longitudinal direction, and the first portion 421 and the second portion 422 are perpendicular to each other and form a regular L-shaped air return duct 42. One end of the air return duct 42 is also opposite to the fan 3, and specifically, the first portion 421 is opposite to the fan 3. So that the fan 3 operates and sucks the wind out of the first portion 421 and blows it into the air outlet duct 41.
The defrosting system further comprises a communicating air duct 43 for accommodating the heating device 2, and two ends of the communicating air duct 43 are respectively communicated with the air outlet duct 41 and the air return duct 42. Generally, the communicating air duct 43 is used for accommodating the heating device 2, so the temperature of the communicating air duct 43 is generally higher than that of the air outlet duct 41 and the air return duct 42, and therefore, in order to enable the evaporator 1 to be heated and defrosted uniformly, the number of air outlets on the communicating air duct 43 is smaller than that of the air outlet duct 41 and the air return duct 42. Moreover, of course, if the special communicating air duct 43 is not provided, the heating device 2 can be directly accommodated in the evaporator chamber 10, and the object of the present invention can be achieved.
The defrosting system also comprises a second air pipe 52 which is communicated with one end of the air return passage 42 far away from the fan 3 and extends to the outer side of the evaporator chamber 10. The defrosting system further comprises a second check valve 62 arranged on the second air pipe 52, and the second check valve 62 only allows the air from the air outlet channel 41 to enter the air inwards. The second one-way valve 62 further ensures the tightness of the evaporator chamber 10 and the second one-way valve 62 may be in communication with certain compartments or devices of higher temperature which may also assist in heating the unit 2 so that the temperature of the evaporator 1 is raised evenly and further defrosted.
For example, in this embodiment, the refrigerator further includes a condenser chamber that houses the condenser, and the second check valve 62 of the second air duct 52 is communicated to the condenser chamber. So that higher and useless heat in the condenser can be introduced into the evaporator chamber 10 through the second check valve 62 to cause the temperature in the evaporator chamber 10 to be further raised, and also to save energy.
In addition, the fan 3 is a cross-flow fan 3, the cross-flow fan 3 is a fan 3 which has a multi-blade type, long cylindrical shape and forward multi-wing blades, and the airflow of the fan 3 passes through the impeller and flows, and the airflow is subjected to the twice force action of the blades, so that the airflow can reach a long distance. Moreover, the air outlet is free of turbulence and more uniform. In the present embodiment, the cross flow fan 3 is adopted to blow the heat generated by the heating device 2 to various parts of the air duct 4, and uniformly heat and defrost the evaporator 1.
To sum up, in the refrigerator adopted by the utility model, the defrosting system in the refrigerator is independent of the refrigeration system, and is provided with an additional fan 3, an air duct 4 and a heating device 2; the fan 3, the air duct 4 and the heating device 2 can generate heat and radiate the heat around the evaporator 1 so as to heat and defrost the evaporator 1. In addition, the independent fan 3 and the independent air channel 4 do not need to occupy the refrigerating fan 3 and the refrigerating air channel 4 of the refrigerating system and are matched with the independent evaporator chamber 10, so that the defrosting effect is better.
