Abstract
The invention discloses a turbofan positioning structure used with a ventilation hood-like microwave oven, comprising a turbofan and a supporting frame. The turbofan and the supporting frame are fixed together via a fixation mechanism. The fixation mechanism comprises a first insertion rib and a second insertion rib, which are respectively arranged at the two ends of a turbofan shell contacting with the supporting frame; a first insertion groove and a second insertion groove are arranged on the supporting frame for the first and the second insertion ribs to insert therein; a positioning baffle is arranged on the supporting frame and positioned beside the turbofan to limit the insertion position of the turbofan. With the positioning baffle in insertion positioning mode, the assembly accuracy during the production process is greatly increased. The turbofan and the supporting frame are fixed as a whole via bolts, so as to reduce the vibration noise. The positioning baffle can definitely define the placement position of the turbofan, so as to avoid the misplacement and thus to ensure the accurate assembly.

In addition, end face one side of cooking cavity 31 forms air outflow port 31b.Air outflow port 31b is the air that flows to cooking cavity 31 inside, plays the outflow pathway effect.Air outflow port 31b is preferably to greatest extent away from the distribution chamber 40 that is provided with air inflow aperture 31a, that is, cooking cavity 31 upper right that are arranged in accompanying drawing are advisable.
In addition, press above-below direction between the rear wall 47 at formation 40 back sides, distribution chamber and the micro-wave oven backboard 51 and form path 49.The oil smoke that produces in the time of can discharging the culinary art of culinary art machine such as gas furnace by path 49.That is, the oil smoke that produces when being positioned at culinary art machines such as the gas furnace culinary art of micro-wave oven below under the effect of turbofan 39, flow in the micro-wave oven by path 49, and the exhaust portion 37a by ventilation grill 37, is discharged.
As shown in Figure 2, the turbofan 39 of prior art is placed on the bracing frame 1, turbofan 39 just is close on the bracing frame 1 with the contact-making surface 10 of bracing frame 1, both are not fixed together, mobilizable space is very big, fan can produce vibrating noise when rotating, and the operator to place the free degree too big.
Summary of the invention
Technical problem to be solved by this invention is, a kind of minimizing vibrating noise is provided, the turbine fan positioning structure that makes the ventilation hood type microwave furnace that turbofan and bracing frame be fixed as one easy for installation.
The technical solution adopted in the present invention is: a kind of turbine fan positioning structure of ventilation hood type microwave furnace, comprise turbofan, bracing frame, and turbofan and bracing frame are fixed together by fixing means.
Described fixing means is: be respectively arranged with at the two ends of the contact-making surface of the turbofan shell that contacts with bracing frame and insert rib and second perpendicular to first of the outstanding formation of contact-making surface and insert rib; On bracing frame, be provided with and insert first insertion groove and second insertion groove that the first insertion rib and second inserts rib.
Also be provided with positioning baffle on bracing frame, positioning baffle is positioned at the turbofan side, the insertion position of restriction turbofan.
First side of inserting the rib and first insertion groove is provided with the screw that the two is secured together.
Second side of inserting the rib and second insertion groove is provided with the screw that the two is secured together.
The described first insertion rib and the second insertion rib and turbofan shell are integrally formed, and described first insertion groove, second insertion groove and positioning baffle and bracing frame are integrally formed.
