[0018] In order to fully utilize the kitchen space and highly integrate various functions, the shell is arranged on the smoke collecting hood, and the shell is located on one of the left and right sides of the fan frame.

[0019] In order to form a heat dissipation channel, a first opening is opened on the side of the fan rack close to the shell, and a second opening is opened on the side of the shell close to the fan rack.

[0025] Compared with the prior art, the utility model has the advantages that the condensed water generated by the refrigeration component is low-temperature condensed water. After the condensed water flows into the condensed water waterway by gravity, it can effectively cool the oil net, improve the oil net's efficient condensation and separation of oil smoke, and achieve the oil net's ability to efficiently filter oil smoke particles. By setting a heat dissipation channel, the fan can extract the air flowing through the condenser and the compressor to achieve heat dissipation and cooling of the condenser and the compressor. Due to its large air volume and air pressure, the fan ensures the heat dissipation effect of the condenser, and also eliminates the special condenser heat dissipation fan in the traditional refrigeration component, so the cost can be made lower. By setting a baffle, the baffle is used to improve the airflow state in the fan frame on the one hand, so that the fan can better absorb and exhaust oil smoke. On the other hand, the baffle has a certain opening and closing angle to limit the size of the first opening of the fan frame side plate to prevent the wind pressure in the fan frame from being released and affecting the smoke extraction effect of the range hood assembly.

[0038] See also Figure 2-3 and Figure 7 , the refrigeration assembly 2 also includes an evaporator 22, a condenser 23 and a compressor 28, all of which are arranged in the shell 21.

The second water receiving pan 25 is provided with a second drain hole 251. The condenser 23 is clamped on the second water receiving pan 25.

[0039] See also Figure 2 to Figure 6 The fume collecting hood 11 is provided with an air inlet 111. The fume suction assembly 1 further includes an oil net 12 arranged at the air inlet 111. The oil net 12 is provided with a condensed water channel 100 for the condensed water generated by the refrigeration assembly 2 to flow through.

[0040] The oil net 12 is provided with grille bars 121 arranged corresponding to the air inlet 111. There are at least two grille bars 121, each of which is arranged along the width direction of the air inlet 111 ( Figure 2 The grille bars 121 extend in the longitudinal direction of the air inlet 111 (in the longitudinal direction shown in FIG. Figure 2 The spacing is set in the left and right directions as shown in the figure.

[0041] The inner side of the grid bar 121 is hollow, and the inner side of the grid bar 121 forms a condensed water channel 100. The oil net 12 also includes a first connecting pipe 122 and a second connecting pipe 123.

[0042] The refrigeration assembly 2 further includes a first drain pipe 26 capable of guiding the condensed water discharged from the second drain hole 251 to the grid bar 121, one end of the first drain pipe 26 is in communication with the second drain hole 251, and the other end of the first drain pipe 26 is in communication with the condensed water path input end 1221. The refrigeration assembly 2 further includes a second drain pipe 29 capable of guiding the water in the condensed water path 100 to the oil cup 17, one end of the second drain pipe 29 is in communication with the condensed water path output end 1231, and the other end of the second drain pipe 29 is directly or indirectly connected to the oil cup 17. In this embodiment, a fixed panel 18 is further provided at the bottom of the smoke hood 11, and the fixed panel 18 is located between the oil net 12 and the oil cup 17. The rear end of the fixed panel 18 is located above the oil cup 17, and one end of the second drain pipe 29 away from the condensed water path output end 1231 is located on the inner side of the fixed panel 18, and the water discharged from the second drain pipe 29 flows into the oil cup 17 after passing through the fixed panel 18.

[0043] The first water receiving tray 24 is used to hold the condensed water generated by the evaporator 22. The condensed water generated by the evaporator 22 will flow to the first water receiving tray 24 by gravity. The first water receiving tray 24 is provided with a first drainage hole 241. The water discharged from the first drainage hole 241 will flow to the condenser 23 to directly irrigate and dissipate the heat of the condenser 23. The water that is not evaporated by the condenser 23 will flow to the second water receiving tray 25, and then be discharged through the second drainage hole 251, and then flow through the first drainage pipe 26 to be introduced into the condensed water waterway 100 in the oil net 12. When the refrigeration component 2 works for a long time and generates too much condensed water, when the water in the condensed water waterway 100 in the oil net 12 accumulates to a certain extent, the condensed water will flow to the oil cup 17.

[0044] The condensed water of the refrigeration component 2 is low-temperature condensed water. After the condensed water flows into the condensed water channel 100 by gravity, it can effectively cool the oil net 12, improve the efficient condensation and separation of oil smoke by the oil net 12, and realize the efficient filtering ability of oil smoke particles by the oil net 12. The effective use of the condensed water of the refrigeration component 2 can avoid the cost burden caused by the external water box and the atomized condensed water.

[0045] The source of the condensed water may also be only from the evaporator 22 or the condenser 23. In addition, the condensed water from the evaporator 22 and the condenser 23 does not necessarily have to be first merged and then passed to the oil network 12, and may also be separately received and then passed to the oil network 12.

[0046] See also Figure 2 and Figure 7The fan frame 13 is provided with a first chamber 131 for accommodating the fan 14, the housing 21 of the refrigeration assembly 2 is provided with a second chamber 211 for accommodating the condenser 23, and the range hood further includes a heat dissipation channel connecting the first chamber 131 and the second chamber 211. In this embodiment, the compressor 28 is also arranged in the second chamber 211.

[0047] A first opening 132 is formed on the side of the fan frame 13 close to the housing 21 , and a second opening 212 is formed on the side of the housing 21 close to the fan frame 13 . The first opening 132 and the second opening 212 are correspondingly arranged, and the first opening 132 and the second opening 212 constitute the above-mentioned heat dissipation channel.

[0048] By providing a heat dissipation channel, the fan 14 can extract the air flowing through the condenser 23 and the compressor 28, thereby achieving heat dissipation and cooling of the condenser 23 and the compressor 28. The fan 14 ensures the heat dissipation effect of the condenser 23 due to its large air volume and air pressure, and also eliminates the need for a dedicated condenser heat dissipation fan in a traditional refrigeration assembly, so the cost can be lowered.

[0049] See also Figure 2 and Figure 7-Figure 8 A baffle 15 capable of opening or closing a first opening 132 is disposed on the side of the fan frame 13 close to the housing 21. The fan 14 includes a fan input end 141, which is disposed toward the side of the housing 21 where the first opening 132 is disposed. When the baffle 15 is open, the baffle 15 gradually tilts from bottom to top toward the fan input end 141.

[0050] The fume extraction assembly 1 further includes a motion mechanism 16 for driving the baffle 15 to open or close. The motion mechanism 16 includes a linear drive module, which includes a motor 161, a screw rod 162, and a slider 163. The screw rod 162 is driven by the motor 161 to rotate along its own axis. The screw rod 162 is arranged longitudinally. The slider 163 can move along the extension direction of the screw rod 162 as the screw rod 162 rotates.

One end of the connecting rod 164 is rotatably connected to the slider 163, and the other end of the connecting rod 164 is rotatably connected to the baffle 15.

[0051] On the one hand, the baffle 15 is used to improve the airflow state in the fan frame 13, so that the fan 14 can better absorb and exhaust oil smoke. On the other hand, the baffle 15 has a certain opening and closing angle to limit the size of the first opening 132 of the side plate of the fan frame 13, to prevent the wind pressure in the fan frame 13 from being released, which affects the smoke extraction effect of the oil smoke extraction component 1.
