Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a split-type range hood. Background Art

[0002] In modern kitchens, range hoods have become one of the indispensable equipment. Its main function is to collect and discharge oil smoke or water vapor during the cooking process, thereby protecting the kitchen environment. The main working principle is that the main motor in the inner cavity of the fuselage rotates at a high speed to drive the impeller in the centrifugal fan to rotate, thereby generating a large negative pressure in the preset inner cavity. The cooking oil smoke is sucked into the range hood along the fan due to the atmospheric pressure and the airflow induced effect to be discharged outdoors or to the public flue. During the whole process, because the impeller rotates at a high speed and rubs against the flowing air, strong aerodynamic noise will be generated; in addition, the vibration of the high-speed motor forces the range hood to resonate, accompanied by electromagnetic noise and mechanical noise, which are amplified through the cavity of the fuselage and diffused outward from the air inlet of the range hood. Therefore, common range hoods will have a large noise pollution problem when working, affecting the physical and mental health of users.

[0003] In the prior art, in order to solve the above-mentioned noise pollution problem, there is currently a ceiling range hood that separates the fan system from the main body of the machine. When installed, the fan system, as a noise source, is far away from the human ear. In theory, the noise felt by the user when using the range hood will be smaller. However, due to the variety of kitchen environments, the space from the top ceiling to the floor is even more different, which to some extent restricts the installation environment of the range hood. That is, when the ceiling space in the user's home is too small to accommodate the fan of the range hood, this type of range hood cannot be used. The use scenario is limited by the installation environment. Summary of the invention

In addition, a mounting hole 25 is provided at the edge of the multiple air inlets, and a connecting hole 26 is provided on the cover plate 5 and / or the air outlet end of the ventilation assembly 4. The screw passes through the connecting hole 26 and is connected to the mounting hole 25, so that the cover plate 5 and / or the ventilation assembly 4 are installed together with the air inlet by the screw. More preferably, since the positions of the connecting holes 26 at the multiple air inlets are the same, that is, the positions of the connecting holes 26 at the first air inlet 211 and the second air inlet 212 are the same, the cover plate 5 can be universally installed at any one of the multiple air inlets.

Since mounting holes 25 are provided at the multiple air inlets, corresponding connecting holes 26 are provided on the cover plate 5 and / or the air outlet end of the ventilation assembly 4, and screws are connected to the mounting holes 25 after passing through the connecting holes 26, so that the cover plate 5 and / or the ventilation assembly 4 are installed together with the air inlet by screws. More preferably, the area of ​​the air outlet end of the second joint 43 is larger than the area of ​​its air inlet end, and at the same time, since the opposite side walls at the second joint 43 are symmetrically arranged, specifically, the opposite side walls of the second joint 43 are symmetrically arranged, so that the angle between the air inlet end and the air outlet end on the left side of the second joint 43 is equal to the angle between the air inlet end and the air outlet end on the right side of the second joint 43.

[0053] In this embodiment, if the space above the ceiling of the user's home is large enough, the cabinet 2 of the range hood can be placed horizontally so that the cabinet 2 is completely hidden in the space above the ceiling, and the air outlet direction of the fan 3 can be selected according to the position of the smoke exhaust duct. Specifically, if the air outlet is required to be on the left, the air outlet 22 is set to face the left, the ventilation component 4 is connected to the second air inlet 212, and the first air inlet 211 is sealed by the cover plate 5; if the air outlet is required to be on the right, the connection scheme is the same as the above-mentioned setting of the air outlet on the left, and it is only necessary to rotate the cabinet 2 180° around the baffle 24.

[0054] Of course, if the space above the ceiling of the user's home is too small to accommodate the cabinet 2 of the range hood, during the installation process, the operator can place the cabinet 2 vertically in the upper space of the ceiling, so that the rear wall of the cabinet 2 is set parallel to the wall, and the cabinet 2 is placed in the upper space of the ceiling as much as possible. Similarly, as when the cabinet 2 of the range hood is placed horizontally, the vertically placed cabinet 2 can also select the air outlet direction of the fan 3 according to the position of the smoke exhaust duct. Specifically, if the air outlet is required on the left, the air outlet 22 is set to the left, the ventilation component 4 is connected to the first air inlet 211, and the first air inlet 211 is sealed by the cover plate 5; if the air outlet is required on the right, the connection scheme between the cabinet 2 and the ventilation component 4 is the same as the above-mentioned left air outlet setting, and the cabinet 2 only needs to be rotated 180° around the second joint 43.
