AI Technical Summary
In existing range hoods, oil leakage is prone to occur at the connection between the motor and the fan cabinet after prolonged use, with grease flowing out along the outer wall of the fan cabinet, and there is a lack of effective solutions.
Design an oil circuit structure for a range hood, including a fan housing and a motor base housing. The fan housing has an oil receiving part and an oil drain port at the bottom. The motor base housing is fixed to the fan housing with screws. The oil receiving part intercepts the seeping grease and guides it into the fan housing through the oil drain port. The volute and oil outlet are used to further guide the grease out.
It effectively intercepts and drains leaked grease, preventing grease from flowing down the outer wall of the air handling unit, improving connection sealing and structural strength, and reducing oil leakage.

[0013] Compared with the background art, the effect of the present application is that the oil collection part arranged below the motor installation opening can intercept the oil seepage from the motor installation opening, so that the oil can not flow downwards along the outer wall of the air cabinet shell, and the oil intercepted by the oil collection part can be discharged through the oil discharge opening. BRIEF DESCRIPTION OF DRAWINGS
[0014] Fig. 1 The present application provides a structural schematic diagram of the air cabinet shell;
[0015] Fig. 2 The present application provides a structural schematic diagram of the air cabinet shell;
[0016] Fig. 3 The present application provides a structural schematic diagram of the air cabinet shell; DETAILED DESCRIPTION
[0017] In order to deepen the understanding of the present application, the present application will be further described in combination with embodiments and drawings, and the embodiments are only used to explain the present application and do not constitute a limitation on the protection scope of the present application.
[0018] Please refer to Figs. 1-3 The present application provides an oil path structure of an extractor hood, which comprises an air cabinet shell 1 and a motor bottom shell 2, the air cabinet shell is provided with a motor installation opening 3, the motor bottom shell is installed on the motor installation opening, the motor bottom shell is used for installing a motor, an oil collection part 4 is arranged on the outer wall of the air cabinet shell 1 at a position below the motor installation opening, the oil collection part is used for collecting the oil seepage from the motor installation opening and the motor bottom shell, so as to avoid the oil seepage along the outer wall of the air cabinet shell downwards, the oil collection part is provided with an oil discharge opening 5 at a lower position, the oil intercepted by the oil collection part is gathered to the oil discharge opening and discharged through the oil discharge opening under the action of gravity.
[0019] Preferably, the oil discharge opening 5 is connected with the inside of the air cabinet shell 1, the oil itself seeps out from the inside of the air cabinet shell, so that the oil is discharged back to the inside of the air cabinet shell, and the oil is concentrated and guided to the oil cup by the oil guiding structure arranged on the air cabinet shell.
[0020] The bottom wall of the air cabinet shell 1 is provided with a recessed oil collection area 6, the oil collection area is connected with an oil discharge pipe 7 at a lower position, the oil on the inner wall of the air cabinet shell will finally gather in the oil collection area under the action of gravity, and finally discharged through the oil discharge pipe, and the oil discharge pipe can be connected with the oil cup of the extractor hood.
[0021] The wind cabinet shell 1 is internally provided with a volute 8 for guiding the exhaust oil fume, and the oil discharge port 5 is located inside the volute, and the bottom of the volute is provided with an oil outlet 9, and since the volute itself has the problem of accumulated oil, the oil discharge port can be connected to the volute, and then the oil is discharged through the oil outlet on the volute, and the oil outlet is located above the oil collection area 6, and the oil discharged from the oil outlet can directly drop into the oil collection area.
