The process of the range hood for sucking the oil smoke follows the principle of air hydrodynamics: in two adjacent space regions, as long as there is a pressure difference, the gas flows from a place where the pressure is high to a place where the pressure is low. When the range hood is in a working state, air in the range hood is exhausted outdoors, so that a negative pressure area with a large pressure difference with the surrounding area is formed in the range hood. At this time, the cooking fumes are sucked into the range hood by the negative pressure region in the process of rising, and then discharged to the outside.

As shown in fig. 1 and fig. 2, an embodiment of the present application provides a range hood, which includes a smoke collection chamber assembly 1, a power assembly 2, and a decoration cover 3. Wherein, power component 2 installs in the top of collection smoke chamber subassembly 1, and power component 2 and the inside intercommunication of collection smoke chamber subassembly 1, form the smoking passageway.

Illustratively, as shown in fig. 4, the power housing 21 includes a power housing main body 211, the power housing main body 211 encloses an accommodating cavity 212, and the front and rear sides of the power housing main body 211 are respectively provided with an installation opening and a maintenance opening (not shown in the drawings) communicating with the accommodating cavity 212. The power housing main body 211 further includes an installation cover plate 213 for closing the installation opening, and a maintenance cover plate 214, the installation cover plate 213 being used for closing the maintenance opening, and the maintenance cover plate 214 being used for closing the maintenance opening. The upper and lower sides of the power shell body 211 are respectively provided with a power air outlet 216 and a power air inlet 215. When the mounting cover plate 213 and the maintenance cover plate 214 respectively block the mounting opening and the maintenance opening, the accommodating chamber 212 communicates with the external space through the power intake opening 215 and the power outtake opening 216.

In the process of installing the power assembly 2, the impeller 24 and the motor 25 are respectively placed at the front side and the rear side of the volute 22, and the impeller 24 extends into the volute 22 from the air inlet at the front side of the volute 22. The output shaft of the motor 25 is then passed through the rear side wall of the volute 22 and connected to the axis of the impeller 24. Then the motor 25 is fixedly installed with the volute 22, and the air inlet ring 23 is installed at the front side air inlet of the volute 22. Finally, the mounted volute 22 is fixed in the receiving chamber 212, and the mounting opening and the service opening are closed by the mounting cover plate 213 and the service cover plate 214. To complete the initial installation of the power module 2.

It should be noted that, when the motor 25 and the scroll casing 22 are fixedly installed, the motor 25 may be fixed to the rear side wall of the scroll casing 22 by screws. Moreover, the rear side wall of the volute casing 22 is also provided with a mounting bracket, and the mounting bracket can be welded and fixed with the volute casing 22, and can also be bonded or directly fixed through screw connection. The mounting bracket is provided with a spiral case threaded hole, the mounting cover plate 213 is provided with a spiral case through hole corresponding to the spiral case threaded hole, the spiral case through hole can sequentially pass through one spiral case through hole through a screw and is fixedly screwed with one spiral case threaded hole, and therefore the spiral case 22 and the mounting cover plate 213 are fixedly connected.

The spiral case is provided with a spiral case through hole, wherein the spiral case through hole is provided with a plurality of spiral case threaded holes and spiral case through holes, such as two, three or more spiral case threaded holes and spiral case through holes, which are arranged in a one-to-one correspondence manner. The mounting cover 213 has a plate-like structure with an approximate rectangle, square or circle, and a plurality of mounting through holes are respectively formed at the edge of the mounting cover 213. The power shell main body 211 is provided with a plurality of mounting threaded holes corresponding to the mounting through holes one to one on the edge of the mounting opening on the front side, and when the mounting opening on the front side of the power shell main body 211 is blocked, each screw penetrates through the mounting through hole in sequence and is in threaded connection with the mounting threaded hole.

The maintenance cover plate 214 is a plate-shaped structure that is approximately rectangular, square or circular, and a plurality of maintenance through holes are respectively formed at the edge of the maintenance cover plate 214. And the power shell body 211 is provided with a plurality of maintenance screw holes corresponding to the maintenance through holes one to one at the edge of the rear maintenance opening, and when the opening is maintained, each screw penetrates one maintenance through hole and is in threaded connection with one maintenance screw hole in sequence, so that the maintenance cover plate 214 is firmly installed at the maintenance opening.

Since the installation cover 213 and the maintenance cover 214 are both plate-shaped structures, the structural strength of the installation cover 213 and the maintenance cover 214 is increased. A rib structure may be provided on the installation cover plate 213 and the maintenance cover plate 214, respectively. Thus, the structural strength of the installation cover plate 213 and the maintenance cover plate 214 can be effectively improved without increasing the thickness of the installation cover plate 213 and the maintenance cover plate 214.

For example, the central region of the mounting cover 213 may be stamped such that the central region and the edge region of the mounting cover 213 are located on two different planes. Thus, the connection between the central region and the edge region of the mounting cover 213 is equivalent to a rib structure, and the structural strength of the mounting cover 213 can be improved.

Accordingly, the central region of the repair cover 214 may also be stamped such that the central region and the edge region of the repair cover 214 are in two different planes. In this way, the connection between the central region and the edge region of the mounting cover 213 also corresponds to a rib structure, thereby increasing the structural strength of the service cover 214.

As shown in fig. 5, fig. 5 is another schematic perspective structure diagram of the range hood in fig. 1. Referring to fig. 3 and 4, in fig. 5, the upper baffle plate of the power housing main body 211, which is provided with the power outlet 216, is removed, so that the accommodating space 212 in the power housing main body 211 can be visually displayed. In the accommodating chamber 212, a volute air inlet 221 at the rear side of the volute 22 is communicated with the accommodating space 212, and a volute air outlet 222 at the upper side of the volute is used for being communicated with a flue of a kitchen through a smoke exhaust pipeline. The electrical box 26 on the upper side of the power shell body 211 is connected with the upper baffle of the power shell body 211, and the power air outlet 216 and the electrical equipment 26 are respectively located on two opposite sides of the upper baffle of the power shell body 211.

The electrical box 26 is electrically connected to the motor 25, and is used for controlling the on/off of the motor 25 and controlling the rotation speed of the motor 25. When the motor 25 is powered on, the motor 25 drives the impeller 24 to rotate at a high speed in the volute casing 22, and under the driving of the impeller 24, the volute casing 22 draws the airflow in the accommodating space 212 through the volute casing air inlet 221, and discharges the airflow to the outside through the volute casing air outlet 222 (power air outlet 216) and the smoke discharge duct via the smoke duct. In this manner, a negative pressure region is formed in the accommodation space 212.

It should be noted that the accommodating space 212 communicates with the smoke collecting chamber in the smoke collecting chamber assembly 1 through the power air inlet 215.

In some embodiments, as shown in fig. 6, fig. 6 is an exploded view of the smoke collection chamber assembly 1 shown in fig. 2. The smoke collection chamber assembly 1 includes a smoke collection chamber housing 11, an oil filter 12, an opening/closing panel 13, an oil tank 14, an operation panel 15, a lamp assembly panel 16, and a decorative strip 17.

Exemplarily, referring to fig. 7 and 8, fig. 7 is a schematic perspective view of smoke collection chamber housing 11 shown in fig. 6, and fig. 8 is a sectional view taken along line a-a in fig. 7. The smoke collection cavity housing 11 includes a smoke collection housing main body 111, wherein the smoke collection housing main body 111 is approximately an inverted L-shaped structure, and includes a vertical section distributed in the up-down direction and a transverse section (not shown in the figure) distributed in the front-back direction. And the lower end of the vertical section is provided with a smoke collecting air inlet 112 forward. Correspondingly, the upper end surface of the vertical section is provided with a smoke collection air outlet 113, and the smoke collection air inlet 112 is communicated with the smoke collection air outlet 113 through a smoke collection air outlet 114.

Wherein, the smoke collecting duct 114 is enclosed by the duct baffle in the smoke collecting casing main body 111. And the smoke collection air outlet 113 is used for being communicated with the power air inlet 215. When the electrical box assembly 26 controls the fan 25 to drive the impeller 24 to rotate, the accommodating cavity 212 communicated with the smoke collection duct 114 is in a negative pressure state, so that the airflow in the smoke collection duct 114 is sucked, and a negative pressure area is also formed in the smoke collection duct 114. The range hood is generally arranged in the upper area of the stove and is in a normal pressure area. Therefore, the smoke collection duct 114 can suck the oil smoke, gas and particulate matters in the area above the stove into the smoke collection duct 114 through the smoke collection inlet 112, and discharge the oil smoke, gas and particulate matters out of the room through the smoke collection outlet 113, the power inlet 215, the accommodating cavity 212, the volute 22 and the power outlet.

In some embodiments, as shown in fig. 7 and 9, fig. 9 is a schematic perspective view of the smoke collection chamber assembly 1 shown in fig. 2. Wherein, the oil filter screen 12 is installed at the smoke collection air inlet 112. When the oil smoke gas enters the smoke collection duct 114 through the smoke collection inlet 112, the oil smoke gas is filtered by the oil filter 12 to realize the first oil smoke separation.

After the oil smoke gas enters the accommodating cavity 212, the oil smoke gas can be subjected to second oil smoke separation through the rotation of the impeller 24. In the process, under the action of the impeller 24, the lampblack gas flowing through the volute 22 is subjected to centrifugal force, and the oil mist is aggregated into oil drops, collected on the inner wall of the volute 22 and flows downwards to be collected.

In the above embodiment, an oil discharge port is formed at the bottom side of the volute casing 22, and the liquid secondary waste oil collected in the volute casing 22 sequentially flows into the oil groove 14 at the lowest end of the smoke collection housing main body 111 through the oil discharge port, the power air inlet 215, the smoke collection air outlet 113, the smoke collection air duct 114, and the bottom side of the smoke collection air inlet 112. Also, since the lower side of the oil screen 12 is aligned with the upper side opening of the oil tank 14, the primary waste oil separately collected through the oil screen 12 can directly flow into the oil tank 14 through the oil screen 12. Therefore, the liquid waste oil gathered in the oil fume separation process of the range hood can be collected through the oil groove 14, and a user only needs to clean the oil groove 14 regularly.

As shown in fig. 9 and 10, fig. 10 is a schematic perspective view of the smoke collecting chamber assembly 1 shown in fig. 2 including the opening and closing panel 13. An opening and closing panel 13 is also installed at the smoke collection air inlet 112. The openable panel 13 is connected to the smoke collection housing main body 111 by a hinge. Thus, when the range hood is opened, the opening and closing panel 13 rotates under the action of the hinge to expose the smoke collection air inlet 112. When the range hood is closed, the opening and closing panel 13 reversely rotates under the action of the hinge, so that the opening and closing panel 13 is close to the oil filter screen 12 and is arranged approximately in parallel with the oil filter screen 12, and the smoke collection air inlet 112 is closed.

The smoke collection chamber housing 11 further comprises, for example, a power device such as a rotary motor or an electric telescopic rod. And the power device is electrically connected to the appliance box assembly 26. When the range hood is started, the electrical box assembly 26 controls the opening and closing panel 13 to rotate through the braking force device so as to open the smoke collection air inlet 112. When the range hood is closed, the electrical box assembly 26 controls the opening and closing panel 13 to rotate reversely through the power device, so as to close the smoke collection air inlet 112.

With continued reference to fig. 9, the light fixture panel 16 has mounted thereon lighting assemblies (not shown), such as led light bulbs, led light strips, and a diffuser. The lamp assembly panel 16 is mounted on the lower side of the transverse section of the smoke collecting housing main body 111, and the light emitting diode lamp beads, the light emitting diode lamp strips and the light homogenizing cover lighting assemblies are arranged downwards. In this manner, when the range hood is mounted above the range, the energized illumination assembly illuminates the space between the range and the lamp assembly panel 16, facilitating the cooking operation of the user. Further, since there is generally a mounting gap between the front end of the cross-cut section and the lamp assembly panel 16, a trim strip 17 may be mounted on the front end surface of the cross-cut section for covering the mounting gap between the lamp assembly panel 16 and the front end of the cross-cut section.

Referring to fig. 10, the front side of the vertical section of the smoke collection housing main body 111 is attached to the operation panel 15 above the smoke collection inlet, and the operation panel 15 is provided with an operation button (not shown), which may be a push type or a body-sensing type, but is not limited thereto.

The operation buttons are generally electrically connected to the electrical box assembly 26, and by operating different operation buttons, the opening or closing of the opening and closing panel 13, the opening or closing of the lighting assembly, the opening and closing of the motor 25, and the rotation speed of the motor 25 can be controlled. The functions of the operation buttons can be integrated, for example, a one-key-on button can control the opening and closing panel 13 to open and control the motor 25 to start rotating, and a one-key-off button can control the opening and closing panel 13 to close and cut off the current of the motor 25. The lighting assembly can be controlled to be turned on or off by a separate lighting button. In addition, the operating button further comprises a speed regulating button for controlling and regulating the rotating speed of the motor 25 so as to realize the regulation of the suction force of the range hood.

As shown in fig. 11, fig. 11 is a schematic perspective view of the smoke collecting chamber assembly 1 and the power assembly 2 shown in fig. 1. In the process of covering the power component 2 by the decoration cover 3 and fixedly installing the decoration cover 3, because the power component 2 is installed at the upper side wall of the smoke collection cavity component 1, no enough space is available between the decoration cover 3 and the power component 2 to connect the decoration cover 3 and the smoke collection cavity component 1. In order to fix the decoration cover 3, the decoration cover 3 is directly connected and fixed with the power assembly 2. However, due to errors in the production and assembly processes, the lower side of the mounted trim cover 3 does not closely conform to the upper side wall of the smoke collection chamber assembly 1.
