Description

Technical Field

[0001] The present invention belongs to the technical field of refrigerators, and particularly relates to a refrigerator with a condenser disposed at the bottom for heat dissipation. Background Art

[0002] For an embedded refrigerator used in an integrated kitchen, since it is in a relatively enclosed space, the ventilation condition is poor, resulting in poor heat dissipation. The humidity in the kitchen is relatively high. Affected by factors such as frequent opening and closing during the use of the refrigerator and its own cold leakage, condensation is likely to occur.

[0003] The back area of the refrigerator is more enclosed, and condensation is likely to appear in this position. The existing solutions usually include increasing the thickness of the back foaming layer or attaching an anti-condensation tube, heating wire, etc. inside the back panel. Increasing the thickness of the foaming layer will reduce the overall volume ratio of the refrigerator, while using an anti-condensation tube or heating wire will increase the production cost and energy consumption of the refrigerator.

[0014] In the condenser bottom-mounted heat dissipation refrigerator according to the present invention, the heat dissipation fan is a centrifugal fan and is arranged inside the fan housing; the first exhaust pipe and the second exhaust pipe with the air outlet direction facing the lower side are arranged on the fan housing.

[0015] In the condenser bottom-mounted heat dissipation refrigerator according to the present invention, a water receiving box is provided below the fan housing and the condenser; a fan support for supporting the fan housing is arranged in the water receiving box.

[0025] The heat dissipation fan 25 is used to discharge the hot air in the compressor chamber 13 and suck in the low-temperature gas outside.

[0026] The back of the box body 1 has a rear panel 15; a first exhaust pipe 21 with an air outlet direction facing the rear panel 15 is provided on the rear side panel of the compressor chamber 13; the heat dissipation fan 25 blows the hot air in the compressor chamber 13 to the rear panel 15 through the first exhaust pipe 21, avoiding condensation on the rear panel 15.

[0027] Further, a plurality of suction holes 131 are provided on the rear side panel of the compressor chamber 13; external air enters the compressor chamber 13 through the suction holes 131, forming an air flow cycle to achieve heat dissipation.

[0028] As an embodiment, the air outlet direction of the first exhaust pipe 21 is parallel to the rear panel 15; the hot air flows upward along the surface of the rear panel 15 and gradually spreads in the width direction during the flow, so that condensation does not appear on the entire surface of the rear panel 15.

[0029] Further, the rear panel 15 is provided with a main diversion groove 151 that runs vertically and is communicated with the first exhaust pipe 21; both sides of the main diversion groove 151 are respectively communicated with a plurality of diversion branch grooves 152; during the flow of the hot air along the main diversion groove 151, it is divided at each diversion branch groove 152, and then overflows from the upper edge of the diversion branch groove 152 and flows upward. The hot air is more evenly distributed on the surface of the rear panel 15, avoiding dead corners.

[0030] Preferably, the diversion branch groove 152 is inclined upward; the path of the hot air is extended, and the hot air can also reach the edge part of the rear panel 15, completely eliminating condensation.

[0031] Those skilled in the art can adaptively set the inclination angle of the diversion branch groove 152. The inclination angle of the diversion branch groove 152 of the present invention is 20-30°.

[0032] The present invention arranges the condenser 4 in the compressor chamber 13 and uses the heat dissipation fan 25 to discharge hot air to the rear plate 15, so that the temperature of the surface of the rear plate 15 rises and condensation is avoided. The present invention uses the heat generated by the condenser 4 and the compressor 3 to eliminate condensation, without increasing the thickness of the foaming layer, and without using an anti-condensation tube or a heating wire. The condensation problem on the back of the refrigerator is effectively solved without occupying the storage volume of the refrigerator and increasing the manufacturing cost.

[0034] The centrifugal fan has a small thickness and occupies a limited space. The heat dissipation airflow is discharged through the first exhaust pipe 21 and the second exhaust pipe 22 by the heat dissipation fan 25, thereby eliminating condensation at the back and bottom of the refrigerator.

[0035] Furthermore, the heat dissipation fan 25 is disposed between the compressor 3 and the condenser 4, so as to better discharge the heat generated by the two.

[0036] Preferably, the bottom of the box body 1 has a bottom plate 14, and the bottom plate 14 is connected to the baffle plate 16; the press chamber 13 is formed on the side and rear of the baffle plate 16; the gas discharged from the second exhaust pipe 22 flows along the baffle plate 16 and the bottom plate 14, and is finally discharged from the front side of the box body 1.

[0037] As an embodiment, an air suction groove 5 is provided at the bottom of the press chamber 13 , and the external low-temperature gas close to the ground can be sucked into the press chamber 13 through the air suction groove 5 , effectively reducing the temperature inside the press chamber 13 .

[0038] As an embodiment, a water receiving box 24 is provided below the fan housing 2 and the condenser 4 to receive the defrost water. The heat dissipated by the condenser 4 is used to accelerate the evaporation of the defrost water. Figure 5 Furthermore, a fan bracket 23 for supporting the fan housing 2 is provided in the water receiving box 24; a gap is formed between the fan housing 2 and the bottom of the water receiving box 24, and the pipeline connecting the compressor 3 and the condenser 4 passes through the gap, making full use of the space. At the same time, the condensed water is used to liquefy the refrigerant in the pipeline, thereby improving the refrigeration efficiency.

[0039] Furthermore, the fan housing 2 is provided with a third exhaust pipe 26 extending into the water receiving box 24; hot air is blown into the water receiving box 24 to promote the evaporation of defrosted water. More preferably, an exhaust branch pipe 27 is connected to the side wall of the second exhaust pipe 22, and the exhaust airflow of the second exhaust pipe 22 generates a negative suction effect in the exhaust branch pipe 27, promoting the exhaust of the gas in the water receiving box 24.

[0040] Preferably, the included angle between the exhaust manifold 27 and the second exhaust pipe 22 of the present invention is 30 - 40°.
