Description

Fume exhaust fan

Technical Field

The invention relates to a range hood.

Background

Range hood is the electrical apparatus that is essential in the kitchen at present, and is comparatively common and use more extensively to arrange oily smoke purification system in last.

At present, the upward-exhaust oil fume purification system is mainly divided into two types: a top-suction range hood and a near-suction range hood. The top-suction type range hood is more attractive, but the smoke inlet is higher, and the smoke suction effect is limited; compared with a top-suction range hood, the near-suction range hood has a lower smoke inlet, but is influenced by the appearance structure and the internal air duct structure of the near-suction range hood, and the existing near-suction range hood cannot better approach oil smoke, so that the oil smoke suction effect is limited to a great extent.

For the smoke inlet duct which is vertically arranged, although the smoke inlet duct is closer to a smoke source, the generated smoke can be sucked away quickly, because the smoke inlet duct is relatively thin, in order to install a switch on the front side of the range hood, a switch abdicating groove structure needs to be arranged on the front side of the smoke inlet duct to prevent the switch from being in a smoke channel or an oil stain environment. Especially for large size switches, the larger the requirement for the size of the relief groove. The size of the large abdicating groove compresses the original thin smoking flue to a certain degree, and the special-shaped structure on the outer surface of the abdicating groove generates a certain resistance to the suction of oil smoke, thereby having negative effects on the oil smoke suction effect and the noise. If the switch is arranged at the front side of the fan, the cabinet cannot be completely wrapped outside the fan in order to operate the switch, and the overall attractiveness of the product is affected.

Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

As shown in fig. 1 to 5, the range hood of the present embodiment includes a housing 1 and a fan system 2 disposed in the housing 1. The lower part of the shell 1 is provided with a vertically extending smoke inlet cavity 11, the front side wall of the lower part of the shell 1 is provided with a smoke inlet 111 communicated with the smoke inlet cavity 11, the upper part of the shell 1 is provided with a smoke collecting cavity 12 communicated with the smoke inlet cavity 11, the smoke collecting cavity 12 extends forwards to form a mounting cavity 13 for mounting the fan system 2, it should be noted that the mounting cavity 13 is used for mounting the fan system 2, but the mounting position of the fan system 2 is not completely limited in the mounting cavity 13, and because the smoke collecting cavity 12 and the mounting cavity 13 are integrated, when the fan system 2 is mounted, the part of the fan system 2 can be positioned in the smoke collecting cavity 12 according to requirements. The air inlet 21 of the fan system 2 may be arranged in advance or in the rear direction, as long as it is communicated with the smoke collecting cavity 12, and the air outlet 22 of the fan system 2 is arranged upward. An oil collecting cup 4 with an upward opening is arranged at the lower edge of the shell 1, and the bottom of the smoke inlet cavity 11 is connected with the oil collecting cup 4. Because the smoke inlet cavity 11 at the lower part of the shell 1 vertically extends, the smoke inlet cavity 11 can be made thinner along the width in the front-back direction and can extend downwards to be sufficiently close to the cooker and a smoke generating source, so that the smoke can be quickly sucked into the smoke inlet cavity to be discharged upwards once being generated, and the smoke suction effect is improved.

In this embodiment, the whole configuration of the range hood leaves the bottom of the installation cavity 13 vacant, and the part of the smoke inlet cavity 11 does not shield the bottom of the installation cavity 13, and the switch panel 5 and the lighting assembly 6 are arranged at the bottom of the installation cavity 13 in this embodiment. The switch panel 5 of the present embodiment is used for controlling the switch and various function switching of the range hood, and the switch panel 5 is tiltably disposed on the housing 1 and is tilted to a state of being vertically disposed at the bottom of the mounting cavity 13 in a working state. The illumination assembly 6 is used to provide direct illumination to the cooktop.

Specifically, as shown in fig. 2 and 3, the upper portion of the housing 1 has a fan frame 14 for mounting the fan system 2, an inner cavity of the fan frame 14 forms the smoke collecting cavity 12 and the mounting cavity 13, and the top of the fan system 2 is fixedly mounted on an inner top wall of the fan frame 13. The upper portion of the casing 1 is provided with a fan housing 15 covering the periphery of the installation cavity 13, the fan housing 15 is located outside the fan frame 14, a relatively closed installation space 150 is formed between the inner bottom wall of the fan housing 15 and the outer bottom wall of the fan frame 14, and the switch panel 5 and the lighting assembly 6 are both arranged in the installation space 150. The bottom wall of the fan housing 15 is provided with a first opening 151 for the switch panel 5 to be turned out downwards and a second opening 152 for the light of the lighting assembly 6 to pass through.

The switch module 51 includes a control panel, a power supply, and the like, and the structure is a mature technology in the prior art and is not described herein. The bottom wall of the blower housing 15 is gradually inclined downward from front to back, and in a state where the switch assembly 51 of the switch panel 5 is hidden in the installation space 150, the outer surface of the display screen 52 is substantially aligned with the outer bottom wall of the blower housing 15, which not only increases the volume of the installation space, but also gives consideration to the aesthetic appearance. For the convenience of connection, an actuating member 53 capable of driving the switch panel 5 to turn is provided in the installation space 150, and a power output 531 of the actuating member 53 is connected to the connecting arm 511. For the convenience of assembly, the connecting arm 511 is L-shaped, the lower end of the L-shaped connecting arm 511 is fixedly connected with the back of the switch assembly 51, and the upper end of the L-shaped connecting arm 511 is connected with the power output end 531 of the driving member 53. The driving member 53 is a motor disposed near the front edge of the first opening 151, and the upper end of the L-shaped connecting arm 511 has a boss 512 connected to a power output 531 of the motor.

The bottom wall of the fan housing 15 of this embodiment is further provided with a start switch 54 capable of controlling whether the switch panel 5 is turned over, and the start switch 54 and the switch panel 5 are both connected with the control system through electric signals. The start switch 54 is provided to facilitate the control of whether the switch panel 5 is turned on or not and the turning angle as required, so as to meet the user's requirements. For example, when the switch panel 5 is in the closed state, the switch panel 5 starts to turn outward when the start switch is pressed, and if the start switch 54 is no longer pressed, the switch panel 5 automatically stops when the display screen 52 turns to the vertical state; if the start switch 54 is pressed when the display screen 52 does not reach the upright position, the angle of the display screen 52 can also stay there to meet more consumer demands; when the display screen 52 is in the vertical state, the start switch 54 is pressed halfway without operation, the switch panel 5 can be turned over until the switch assembly 51 is hidden in the installation space 150, and the display screen 52 is substantially flush with the lower wall surface of the blower housing 15.
