[0036] Reference Figures 1-8 An under-sink built-in refrigerator with built-in drawers includes a cabinet 1, a compressor 8, a condenser 10, an evaporator 20, a dryer filter 21, a return air heat exchanger 22, and a capillary tube 23. It also includes a refrigerator compartment 2 and a freezer compartment 3 arranged side-by-side within the cabinet 1. Guide rails 4 are arranged side-by-side in both the refrigerator compartment 2 and the freezer compartment 3, and a drawer 5 is installed between the two guide rails 4. Ventilation holes 500 are provided on the drawer 5, forming a ventilation gap between the drawer 5 and the refrigerator compartment 2 or the freezer compartment 3. Both the ventilation gap and the ventilation holes 500 are for the flow of cold air. The drawer 5 can move linearly back and forth along the two guide rails 4, allowing it to slide into the refrigerator compartment 2 or the freezer compartment 3, while the drawer door 501 closes the refrigerator compartment 2 or the freezer compartment 3, or allows the drawer 5 to slide out of the refrigerator compartment 2 or the freezer compartment 3. A heat dissipation chamber 6 is provided in the cabinet 1 at the lower end of the freezer compartment 3. The heat dissipation chamber 6... A heat insulation layer 7 is formed between the freezer compartments 3 to prevent or reduce heat conduction to the freezer compartments 3. A compressor 8, an exhaust fan 9, and a condenser 10 are installed in the heat dissipation chamber 6. An air inlet 11 and an exhaust outlet 12 are arranged side by side on the left and right sides of the bottom front end of the cabinet 1. The air inlet 11 and the exhaust outlet 12 are separated by a partition 112. The air inlet 11 and the exhaust outlet 12 are connected to the two ends of the heat dissipation chamber 6 respectively. The exhaust fan 9 is used to exhaust heat from the exhaust outlet 12 to the outside of the cabinet 1, and the heat dissipation speed is fast. An evaporator 20 is installed in the cabinet 1 on the back of the freezer compartment 3. A blower 13 is installed on both the refrigerator compartment 2 and the freezer compartment 3 to improve the air flow speed. A heat insulation component 14 is installed at the bottom of the refrigerator compartment 2 for heat preservation. A guide plate 15 is set on the top of the freezer compartment 3 to guide the cold air to flow quickly and evenly from one end to the other end of the freezer compartment 3, and the freezing speed is faster.

[0037] The compressor 8, the exhaust fan 9 and the condenser 10 of the refrigerator are installed in the heat dissipation chamber 6 at the bottom of the cabinet 1, so that heat conduction to the freezing chamber 3 and the refrigerating chamber 2 is avoided or reduced, and the exhaust fan 9 can quickly discharge the generated heat from the exhaust port 12 to the outside of the cabinet 1. Since the air inlet 11 and the exhaust port 12 are arranged at the front end of the bottom of the cabinet 1, the refrigerator will not be affected even if it is embedded in a cabinet. When the refrigerator is embedded in a cabinet, the ground clearance of the refrigerator is very low, but the drawer 5 can move linearly along the guide rail 4, so that the drawer 5 can be translated into or out of the refrigerating chamber 2 or the freezing chamber 3, and it is more convenient to take out or place food and the like. If a traditional side opening door is used, the side will be blocked by the cabinet, and it is also not convenient to take out or place food. Referring to Figure 8 The refrigeration principle of the refrigerator is basically the same as that of the existing refrigerator, but the structure design is more reasonable, and the refrigerator has the advantages of being suitable for being embedded in a cabinet, good heat dissipation effect, and convenient food taking and placing.

[0038] The air supply fan 13 arranged on the freezing chamber 3 directly blows the fins at the bottom and the face of the evaporator 20, and then the cold air rises to the bottom of the blocking strip 17 after passing through the air duct guide wall formed by the fin spacing. The air supply hole 170 is arranged on the blocking strip 17 for air guiding, and a large pressure is formed at this position to form cold air diversion. Most of the cold air passes through the air guide plate 15 arranged at the top of the freezing chamber 3 and then comes out from the air distribution port at the front end of the air guide plate 15. Then, an annular air duct is formed in the freezing chamber 3, which can make the temperature at any position in the freezing chamber 3 more uniform. The cold air in the refrigerating chamber 2 enters the refrigerating chamber 2 through the air supply hole 170 in the blocking strip 17, and a high-low pressure difference is formed after entering the refrigerating chamber 2. The cold air and the warm air in the refrigerating chamber 2 are quickly mixed by the air supply fan 13 arranged on the refrigerating chamber 2, and then blown out of the refrigerating chamber 2. The above structure design can make the temperature at any position in the refrigerating chamber 2 and the freezing chamber 3 more uniform, and the refrigerating and freezing speed is faster.

[0039] In some embodiments, an air duct 16 is arranged between the refrigerating chamber 2 and the rear wall of the cabinet 1, and a rectangular blocking strip 17 is arranged in the air duct 16 close to the evaporator 20. Four air supply holes 170 are arranged side by side on the blocking strip, and the air supply amount can be adjusted.

[0040] In some embodiments, the temperature insulation assembly 14 includes an upper partition plate 140 and a lower partition plate 141, and a temperature insulation material layer 142 is fixed between the upper partition plate 140 and the lower partition plate 141. The temperature insulation effect is good, and the noise can be reduced.

[0041] In some embodiments, the barrier strip and the layer of temperature insulation material 142 are made of foam material; foam is a material composed of a large number of gas micro-pores, usually made of polymers such as polyurethane, polystyrene, polyvinyl chloride, etc.; these polymers will form a large number of bubbles during foaming, so that the material has the characteristics of light weight, heat insulation, sound insulation, buffering, etc.

[0042] In some embodiments, a cover plate 18 with a through hole is installed at the front end of the bottom of the cabinet 1, which covers the air inlet 11 and the air outlet 12, and the cover plate 18 can serve the purposes of decoration and preventing mice and the like from entering, without hindering the air inlet and air outlet functions.

[0043] In some embodiments, an air supply fan 13 is installed on the refrigeration chamber 2 near one end of the air duct 16, which mainly serves the purpose of air circulation; two air supply fans 13 are installed side by side on the freezing chamber 3 near one end of the air duct 16, which are used to accelerate the flow speed of cold air.

[0044] In some embodiments, ventilation holes 500 are provided on the bottom wall of the drawer 5 and the side wall near the air supply fan 13, so that cold air can enter the drawer 5 from multiple directions, and the refrigeration is fast and uniform.

[0045] In some embodiments, four height adjustment feet 19 are regularly installed at the bottom of the cabinet 1, which can be a pull-cap nut structure, and the height adjustment feet 19 can be threadedly connected with the cabinet 1, capable of large-size adjustment of the ground clearance and flatness of the cabinet 1, suitable for different height cabinets, and capable of reducing shaking and noise.

[0046] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered as within the scope of the present disclosure. Although embodiments of the present disclosure have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirit of the present disclosure, and the scope of the present disclosure is defined by the claims and their equivalents.
