In the other method, ventilation holes are respectively formed in the front wall and the rear wall of the press chamber 500 to form a heat dissipation circulation air path in the front-rear direction. When it is necessary to increase the heat dissipation effect of the nacelle 500, the skilled person usually increases the number of the rear air inlet and outlet holes 512 of the rear wall of the nacelle 500 to enlarge the ventilation area, or increases the heat exchange area of the condenser 503, for example, a U-shaped condenser with a larger heat exchange area is adopted.
The inventors have innovatively realized that the heat exchange area of condenser 503 and the ventilation area of the press compartment 500 are not as large as possible: in conventional designs that increase the heat exchange area of the condenser 503 and the ventilation area of the cabin 500, problems arise in that the condenser 503 dissipates heat unevenly. Adversely affecting the refrigeration system of the refrigerator 100. To this end, the present invention proposes to define a bottom air inlet 505 adjacent to the condenser 503 and a bottom air outlet 506 adjacent to the compressor 501 in a lateral arrangement at the bottom wall of the cabinet 110, so that the circulation of the heat dissipating air flow is completed at the bottom of the refrigerator 100 without increasing the distance between the rear wall of the cabinet 110 and the cabinet. The refrigerator 100 reduces the occupied space and ensures good heat dissipation of the compressor compartment 500, thereby fundamentally solving the problem that the heat dissipation and the occupied space of the compressor compartment 500 of the embedded refrigerator 100 cannot be balanced, and having particularly important significance. The four corners of the bottom wall 504 of the box 110 may also be provided with support rollers (not shown), and the box 110 is placed on a support surface by the four support rollers, so that a certain space is formed between the bottom wall 504 of the box 110 and the support surface.
The heat dissipation fan 502 is configured to cause ambient air around the bottom intake 505 to enter the compressor compartment 500 from the bottom intake 505, pass through the condenser 503, the compressor 501 in sequence, and then flow from the bottom outlet 506 to the external environment to dissipate heat from the compressor 501 and the condenser 503. In the vapor compression refrigeration cycle, the surface temperature of the condenser 503 is generally lower than the surface temperature of the compressor 501, and therefore, in the above process, the condenser 503 is cooled by the outside air, and the compressor 501 is cooled.
In a preferred embodiment, the plate section 531 of the back plate 510 facing the condenser 503 is a continuous plate surface, i.e. there are no heat dissipation holes on the plate section 531. The inventors have innovatively recognized that reducing the ventilation area of the compressor compartment 500 can create a better heat dissipation airflow path without increasing the heat exchange area of the condenser 503, and still achieve better heat dissipation. This is because the plate sections 531 are continuous plate surfaces, so that the heat dissipation airflow entering the compressor compartment 500 is closed at the condenser 503, thereby ensuring the heat exchange uniformity of each condensation section of the condenser 503, facilitating the formation of a better heat dissipation airflow path, and achieving a better heat dissipation effect. Meanwhile, because the plate sections 531 are continuous plate surfaces, hot air blown out from the press cabin 500 due to the fact that air outlet and air inlet are concentrated at the rear portion of the press cabin 500 in the conventional design is prevented from entering the press cabin 500 again without being cooled by ambient air in time, and adverse effects on heat exchange of the condenser 503 are avoided, so that the heat exchange efficiency of the condenser 503 is guaranteed.
In some embodiments, the two side walls of the press chamber 500 are respectively opened with a side vent 521 along the transverse direction. A vent cover 522 is covered at the side vent hole 521. The vent flap 522 may be formed with grill-type vent apertures. Side openings corresponding to the side vent holes 521 are opened on both side walls of the case 110, respectively, so that the heat dissipation airflow flows to the outside of the refrigerator 100. Thereby further increasing the heat dissipation path and ensuring the heat dissipation effect of the compressor compartment 500. It is understood that both side walls of the box 110 may also be directly used as side walls of the nacelle 500, i.e. the side plates 520 constitute both the side walls of the box 110 and the side walls of the nacelle 500.
In a preferred embodiment, the condenser 503 comprises a first straight section 532 extending laterally, a second straight section 533 extending fore and aft, and a transition curved section 534 connecting the first straight section 532 and the second straight section 533, thereby forming a substantially L-shaped condenser 503 with a suitable heat exchange area. The plate section 531 of the back plate 510 corresponding to the condenser 503 is the plate section 531 of the back plate 510 facing the first straight section 532. The ambient air entering from the side vent 521 directly exchanges heat with the second straight section 533, and the ambient air entering from the bottom air inlet 505 directly exchanges heat with the first straight section 532, so that the ambient air entering into the compressor compartment 500 is further concentrated at the condenser 503, and the uniformity of the overall heat dissipation of the condenser 503 is ensured.
In one embodiment, the bottom wall of the housing 110 is defined by a first horizontal plate 530 and a second horizontal plate 550. The first horizontal plate 530 is located at a front side of the bottom of the refrigerator 100. The bent plate 540 is bent and extended from the rear end of the first horizontal plate 530 to the rear and upward direction. Bending plate 540 extends above second horizontal plate 550. The compressor 501, the heat dissipation fan 502 and the condenser 503 are sequentially arranged on the second horizontal plate 550 at intervals along the transverse direction, and are located in a space defined by the second horizontal plate 550, the two side plates 520, the back plate 510 and the bent plate 540. The bending plate 540 includes a vertical portion 541, an inclined portion 542, and a horizontal portion 543. The vertical portion 541 extends upward from the rear end of the first horizontal plate 530, the inclined portion 542 extends upward and rearward from the upper end of the vertical portion 541 to above the second horizontal plate 550, and the horizontal portion 543 extends rearward from the rear end of the inclined portion 542 to the back plate 510.
The first horizontal plate 530 and the second horizontal plate 550 are spaced apart to form a bottom opening therebetween. In one embodiment, the refrigerator 100 further includes a partition 560. The partition 560 is disposed behind the bending plate 540, and the front portion thereof is connected to the rear end of the first horizontal plate 530, and the rear portion thereof is connected to the front end of the second horizontal plate 550, so as to divide the bottom opening into the bottom air inlet 505 and the bottom air outlet 506 which are horizontally arranged. As can be seen from the foregoing, the bottom air inlet 505 and the bottom air outlet 506 of the embodiment of the invention are defined by the partition 560, the second horizontal plate 550, and the first horizontal plate 530, so that the bottom air inlet 505 and the bottom air outlet 506 have the groove shape with a larger opening size, the air inlet area and the air outlet area are increased, the air inlet resistance is reduced, the air flow is smoother, the manufacturing process is simpler, and the overall stability of the compressor compartment 500 is stronger.
The inclined portion 542 is located at a gap between the first horizontal plate 530 and the second horizontal plate 550, above the bottom intake opening 505 and the bottom outlet opening 506. The slope structure of the inclined portion 542 can also guide and rectify the intake airflow, so that the airflow entering from the bottom air inlet 505 flows to the condenser 503 more intensively, and the problem that the airflow is too dispersed to pass through the condenser 503 more is avoided, thereby further ensuring the heat dissipation effect of the condenser 503. Meanwhile, the slope structure of the inclined portion 542 guides the outlet airflow of the bottom air outlet 506 to the front side of the bottom air outlet 506, so that the outlet airflow flows out of the compressor compartment 500 more smoothly, and the smoothness of airflow circulation is further improved. In a preferred embodiment, the angle between the inclined portion 542 and the horizontal plane is less than 45 °, and the inclined portion 542 provides better guiding and rectifying effects for the airflow.
Further, unexpectedly, the inventors of the present application have innovatively recognized that the slope structure of the inclined portion 542 provides a good suppression effect on the airflow noise, and in prototype tests, the noise of the nacelle 500 having the aforementioned specially designed inclined portion 542 can be reduced by 0.65 db or more.
In addition, in the conventional refrigerator, a bearing plate having a substantially flat plate structure is generally used as the bottom of the refrigerator body 110, the compressor 501 is disposed inside the bearing plate, and vibration generated during operation of the compressor 501 greatly affects the bottom of the refrigerator body 110. In the embodiment of the present invention, as mentioned above, the bottom of the tank 110 is configured as a three-dimensional structure, and the second horizontal plate 550 is used to carry the compressor 501, so as to reduce the influence of the vibration of the compressor 501 on other components at the bottom of the tank 110. In addition, by designing the box body 110 into the above-mentioned ingenious special structure, the structure of the bottom of the refrigerator 100 is compact and reasonable in layout, the whole volume of the refrigerator 100 is reduced, the space of the bottom of the refrigerator 100 is fully utilized, and the heat dissipation efficiency of the compressor 501 and the condenser 503 is ensured.
In some embodiments, a wind shield 570 is also provided at the upper end of the condenser 503. The wind shielding member 570 may be a wind shielding sponge, and fills the space between the upper end of the condenser 503 and the bent plate 540, that is, the wind shielding member 570 covers the upper ends of the first straight section 532, the second straight section 533 and the curved transition section 534, and the upper end of the wind shielding member 570 should abut against the bent plate 540 to seal the upper end of the condenser 503, so that part of the air entering the compressor compartment 500 does not pass through the condenser 503 from the space between the upper end of the condenser 503 and the bent plate 540, and thus the air entering the compressor compartment 500 exchanges heat through the condenser 503 as much as possible, and further improves the heat dissipation effect of the condenser 503.
In some embodiments, the refrigerator 100 also includes a weather strip 580 extending fore and aft. The wind-shielding strip 580 is positioned between the bottom wind inlet 505 and the bottom wind outlet 506, extends from the lower surface of the first horizontal plate 530 to the lower surface of the second horizontal plate 550, and is connected to the lower end of the partition 560, so that the bottom intake opening 505 and the bottom outlet opening 506 are completely isolated by the wind shielding strip 580 and the partition 560, so that, when the refrigerator 100 is placed on a supporting surface, the space between the bottom wall of the cabinet 110 and the supporting surface is laterally divided, so as to allow the external air to enter the cabin 500 through the bottom air inlet 505 at one lateral side of the wind-shielding strip 580 by the heat-radiating fan 502, flows through the condenser 503 and the compressor 501 in turn, finally flows out from the bottom air outlet 506 at the other lateral side of the wind shielding strip 580, therefore, the bottom air inlet 505 and the bottom air outlet 506 are completely isolated, so that the external air entering the condenser 503 and the heat dissipation air exhausted from the compressor 501 are prevented from streaming, and the heat dissipation efficiency is further ensured.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
