Example one

Referring to fig. 1 to 5, a range hood, which is a ceiling-mounted range hood in this embodiment, includes a smoke collecting hood 1, a fan frame 2 disposed above the smoke collecting hood 1, and a fan housing 3 disposed at an outer periphery of the fan frame 2, wherein the fan housing 3 covers three front, left, and right sides of the fan frame 2, and a fan system (not shown) is disposed in the fan frame 2. Alternatively, the range hood may be in other forms as long as the fan frame 2 is provided with a housing provided with an electric control element such as a switch, and the like, which is relatively independent, such as a low-suction type, a top-side integrated type, and the like.

Electric control elements such as a control panel with a switch and a sensor for detecting the concentration of oil smoke and the like are arranged on the smoke collecting cover 1, so that a wire 4 is led out of the smoke collecting cover 1, an electric box 5 is arranged at the top of the fan frame 2, and a main power panel (not shown) is arranged in the electric box 5. The blower housing 2 includes a top plate 21 (i.e., an outlet plate) at the top and a rear plate 22 extending downward from the rear end of the top plate 21, the top plate 21 and the rear plate 22 are separate or integrated, and the electrical box 5 is disposed on the top plate 21. The wire 4 extends rearward from the top inside the hood 1 to the rear side of the rear side plate 22 of the fan frame 2, and since the conventional hood 1 generally has an inner hood and an outer hood, the wire 4 is drawn rearward from a space between the inner hood and the outer hood. The wire 4 extends from the bottom of the rear side plate 22 of the fan frame 2 to the top of the rear side plate 22, then bends and extends on the top plate 21 until extending into the electrical box 5 to be electrically connected with the main power supply board in the electrical box 5. That is, the wire 4 extends along the top plate 21 by being bent upward from the side surface (front, rear, right and left wall surfaces) of the fan frame 2 to the top and then bent on the top plate 21.

In order to facilitate the wiring of the standard wire 4, a wiring groove 23 which is recessed forwards is formed on the rear side plate 22 of the fan frame 2, and the wiring groove 23 extends upwards from the bottom of the rear side plate 22 to the top of the rear side plate 22. The range hood further comprises a first wire pressing cover 61 and a second wire pressing cover 62, wherein the first wire pressing cover 61 covers the wire trough 23 to position the wires 4 in the wire trough 23. The second wire cover 62 covers the top plate 21 and is located between the rear side of the electrical box 5 and the top of the wire trough 23, and limits the portion of the wire 4 which is bent forward from the top of the rear side of the fan frame 2 and extends between the electrical boxes 5, so that the position of the wire 4 is fixed relative to the top of the fan frame 2.

From this, fan frame 2, two line ball covers constitute wire rod 4 jointly and walk the line structure, standardize and walk the line mode, avoid 4 disturbances of wire rod and wire rod 4, connector (the used connector is connected to the wire rod) to be corroded by oil smoke steam, prevent wire rod 4 oil hanging more effectively, reduce cost of maintenance and fault rate simultaneously.

Example two

Referring to fig. 6 and 7, in the present embodiment, the difference from the first embodiment is that the wire 4 is routed from the front side of the blower rack 2. The fan frame 2 includes a fan cover 24 located on the front side and extending downward from the front end of the top plate 21, and the top plate 21 and the fan cover 24 may be of a separate structure or an integral structure.

A cabling channel 23 'is formed on the blower cover 24 and is formed by a forward-rearward recess, the cabling channel 23' extending from the bottom of the blower cover 24 up to the top of the blower cover 24. The wire 4 can be directly bent upwards from the connection part (provided with an abdication gap) of the smoke collecting cover 1 and the front side of the fan frame 2 in the smoke collecting cover 1 and extend into the wiring groove 23' on the front side of the fan frame 2.

The first wire pressing cover 61 ' is arranged on the front side of the wire distributing groove 23 ', the second wire pressing cover 62 ' is arranged above the top plate 21 in a covering mode, the first wire pressing cover 61 ' can be fixed with the fan cover 24 through a buckle, the second wire pressing cover 62 ' can be pressed by the electric box 5 to enable the second wire pressing cover to be free of screw installation, and fasteners such as screws can also be adopted to be fixed on the top plate 21 of the fan frame 2.

EXAMPLE III

Referring to fig. 8 and 9, in the present embodiment, the difference from the second embodiment is that the second wire pressing cover 62 'is eliminated, the electrical box 5 is disposed near the edge of the top plate 21 of the blower frame 2, thereby serving as the second wire pressing cover 62', and the wire 4 extends upwards, bends at the top plate 21, and then directly enters into the electrical box 5, so as to form a top safe and reliable wire outlet channel.

The range hood has a movable component, such as a smoke guide plate 7, and therefore the range hood further comprises a moving mechanism for driving the smoke guide plate 7 to move, such as to lift, the moving mechanism comprises a driving mechanism 81, a transmission mechanism 82 and a guide mechanism 83, the guide mechanism 83 is arranged on the left side and the right side of the fan frame 2, and the specific structure of the moving mechanism can be referred to in the prior application of the applicant, such as the chinese patent with the application number of 201710588478.4, and is not described herein again.

The left and right sides of the fan frame 2 are formed with a clearance groove 25 recessed toward the inside of the fan frame 2 for accommodating the guide mechanism 83 to prevent it from protruding out of the fan frame 2 as a whole. The wiring groove 23 'does not extend to the top of the fan cover 24 any more, but is lower than the top of the fan cover 24, the wire 4 extends from the top of the wiring groove 23' to wind the avoiding groove 25 arranged at the left side or the right side of the fan frame 2, and extends above the top plate 21 above the guiding mechanism 83 to directly enter the electrical box 5. One of the left and right sides of the electrical box 5 corresponds to a corresponding side of the blower housing 2, which is the right side as shown in fig. 8. In the present embodiment, the avoiding groove 25 also plays the same role as the routing groove.
