During working, the oil fume includes much oil and water vapor, an oil water mixture separated from the oil fume will accumulate at the bottom of the wind cavity, through arranging the opening 1102, this portion of oil water mixture can be discharged out of the volute 110, to prevent the oil water mixture from damaging the fan, and this can prevent generating a peculiar smell due to the long-term accumulation of the oil water mixture. A cover plate 132 is connected to the volute 110, and after the assembling of the cover plate 132 is completed, the cover plate 132 can seal the opening 1102, and then the volute 110 is opened and closed through the cover plate 132.

As shown in FIG. 35, FIG. 36, FIG. 20, FIG. 21, FIG. 22, FIG. 23 and FIG. 24,
in any of the above embodiments, the top of the volute 110 comprises an air inlet 1106, the volute 110 comprises an air duct 1104 therein, the bottom of the volute 110 is provided with the opening 1102, and the opening 1102 is opposite to the centrifugal fan 160; the bottom plate 130 is connected to the volute 110, and covers the opening 1102, the volute 110 and the bottom plate 130 enclose a mounting cavity 1103, the volute 110 and the bottom plate 130 comprise the mounting cavity 1103 therein, and the range hood assembly 100 further comprises the centrifugal fan 160 provided in the mounting cavity 1103, and the air intake 1602 of the centrifugal fan 160 deviates from the air inlet 1106.
Wherein, the arrow in FIG. 36 shows the flow direction of the oil fume.
In the embodiment, the volute 110 and the bottom plate 130 constitute a first housing, the volute 110 forms all the side walls and a portion of the bottom wall of the first housing, the air duct 1104 is arranged in the volute 110, and the top of the volute 110 is provided with the air inlet 1106 communicating with the top end of the air duct 1104. The circumferential side of the air duct 1104 in the volute 110is formed with the space of the opening 1102 in the bottom, the bottom plate 130 is connected to the volute 110, and the bottom plate 130 covers the opening 1102 after the mounting of the bottom plate 130 is mounted, to cooperate with the volute 110 to enclose the mounting cavity 1103.
Arranging the opening 1102 and the bottom plate 130 can provide convenience for the disassembling and assembling of the centrifugal fan 160, during disassembling and assembling, users can mount the centrifugal fan 160 inside the first housing through the opening 1102, or take out the centrifugal fan 160 that needs to be repaired or replaced through the opening 1102. The opening 1102 can further be available for the probing operation of a maintenance staff when the centrifugal fan 160 fails. Furthermore, the effects of lowering the assembling difficulty and maintenance difficulty of the centrifugal fan 160 are achieved.
Specifically, when the interior of the range hood assembly 100 needs to be cleaned, users can clean the dirt remaining on the inner surface of the bottom plate 130 after the bottom plate 130 is disassembled, and can further probe via the opening 1102 to clean the dirt remaining on the bottom wall of the volute 110, and thus this provides convenience for users to clean a first liquid storage region and a second liquid storage region, and lowers the possibility that the range hood assembly 100 generates a peculiar smell.
The centrifugal fan 160 is provided inside the mounting cavity 1103, an axial air intake 1602 of the centrifugal fan 160faces downward and deviates from the air inlet 1106 facing upward, and the air intake 1602 and the bottom wall of the mounting cavity 1103 are arranged at an interval. After the centrifugal fan 160 is started, oil fume enters the air duct 1104 via the air inlet 1106from top to bottom and flows laterally via the air duct 1104 to the region between the air intake 1602 and the bottom wall of the mounting cavity 1103, then the oil fume is sucked into the centrifugal fan 160 via the air intake 1602 and is finally discharged into an outer smoke pipe via the circumferential side of the first housing after pressurized by the centrifugal fan 160. Wherein, as the oil fume needs to change direction before it is sucked into the centrifugal fan 160, part of oil and water will be thrown to the bottom wall of the first housing, even if the oil fume is sucked into the centrifugal fan 160, the oil and water adhering to the interior of the centrifugal fan 160 will further drip to the bottom wall of the first housing via the air intake 1602 after the centrifugal fan 160 stops, and furthermore, as the air inlet 1106 is opened in the top of the first housing, the water on the countertop of the range hood assembly 100 will be poured into the first housing directly via the air inlet 1106, and this finally results in the accumulation of huge oil water mixture in the first housing.
On this basis, on the bottom wall of the first housing, at least a portion of the region is concaved towards the inner side of the first housing, to form a boss at the inner side of the first housing and form a groove at the outer side of the first housing. Wherein, the side wall of the boss is provided with a drain hole which penetrates through laterally. Through arranging the boss, the oil water mixture accumulating on the bottom wall of the first housing can laterally flow out of the first housing via the drain hole, and specifically, as the oil water mixture has certain viscosity, the oil water mixture previously flowing out of the drain hole will bring the oil water mixture in the first housing to flow out, and thus the oil water mixture in the first housing is emptied, to meet the need of discharging the liquid inside the first housing, prevent the oil water mixture excessively accumulating in the first housing from damaging other electrical structures, and avoid generating peculiar smells in the first housing.
Thus it can be seen that through constructing the boss and the drain hole on the bottom wall of the first housing, the present disclosure enables the oil water mixture in the first housing to be discharged timely. Furthermore, the effects of optimizing the structure of the range hood assembly 100, improving the practicability of the range hood assembly 100 and improving users' use experience.
Specifically, through constructing an inner-concave boss, the space at the inner side of the first housing can further be reasonably used, and a plugging structure for plugging the drain hole can be arranged at the inner side of the boss and does not protrude out of the bottom face of the first housing, and thus this avoids increasing the thickness of the range hood assembly 100 due to the plugging structure and ensures that the range hood assembly 100 can be placed flat in a cupboard.
