Abstract
The utility model relates to an embedded oven hot air fan, including wheel hub (3) and fan blade (1) more than the one slice of being connected with wheel hub (3), be equipped with oil extraction hole (2) on its characterized in that fan blade (1). The utility model discloses owing to adopt the structure that is equipped with the oil extraction hole on hot air fan's fan blade, when the fan rotated, greasy dirt on the fan blade was collected and flowed to the oil extraction hole, was thrown away the greasy dirt through the centrifugal force effect, consequently, it not only can the self-cleaning greasy dirt, did not need artifical frequent washing, convenient to use has not only significantly reduced moreover because of the rotation resistance that the greasy dirt brought, the noise is big and the short-lived scheduling problem.
Description
Technical field:
The utility model is a kind of embedded baking box hot blast fan, belongs to the renovation technique of embedded baking box hot blast fan.
Background technique:
Existing embedded baking box hot blast fan, operated by rotary motion blows to the heat in the heating chamber in the oven cavity in the heating chamber of baking box, after work a period of time, will have one deck greasy dirt above the fan blade, owing to can not remove voluntarily, greasy dirt can flow into the rotating shaft position, causes fan rotational resistance and starting resistor to increase, shorten working life, and make the fan noise increase, and therefore needing often to clean, dismounting, use are extremely inconvenient.
Practical fresh content:
The purpose of this utility model is to consider the problems referred to above and provides a kind of noise little that the life-span is long, can remove voluntarily to be stained with the greasy dirt that covers, and not need artificial often cleaning, embedded baking box hot blast fan easy to use.
The technical solution of the utility model is: comprise wheel hub and the above fan blade of a slice that is connected with wheel hub, wherein fan blade is provided with oil drainage hole.
Above-mentioned fan blade is provided with stiffening rib, and oil drainage hole is arranged on the outer end of stiffening rib.
The utility model is owing to adopt the structure that is provided with oil drainage hole on the fan blade of hot blast fan, when fan rotates, greasy dirt on the fan blade compiles and flows to oil drainage hole, by centrifugal action greasy dirt is thrown out, therefore, it not only can remove greasy dirt automatically, does not need artificial often cleaning, not only easy to use, and significantly reduced the rotational resistance, the noise that bring because of greasy dirt and reach problems such as the life-span is short greatly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Embodiment:
The utility model structural representation as shown in Figure 1, comprise wheel hub 3 and 1, six fan blade 1 of six fan blades of being connected with wheel hub 3 on be respectively equipped with oil drainage hole 2.In the present embodiment, for greasy dirt on the fan blade effectively being compiled and flowing to oil drainage hole, oil drainage hole 2 is arranged on the outer end of every fan blade.
For preventing the fan blade distortion, the back side of fan blade 1 also is provided with stiffening rib 11, and oil drainage hole 2 is arranged on the outer end of stiffening rib 11.
Claims (2)
1, a kind of embedded baking box hot blast fan comprises wheel hub (3) and the above fan blade of a slice (1) that is connected with wheel hub (3), it is characterized in that fan blade (1) is provided with oil drainage hole (2).
2, embedded baking box hot blast fan according to claim 1 is characterized in that above-mentioned fan blade (1) is provided with stiffening rib (11), and oil drainage hole (2) is arranged on the outer end of stiffening rib (11).
