1. A connected cooking appliance comprising:
a sensor;
a housing comprising a thermally conductive material arranged at a superior end of an internal cooking cavity of the connected cooking appliance, the housing defining a housing cavity fluidly coupled to an air inlet,
wherein the housing is configured to locate the sensor at a mounting point superior to the cooking cavity, an air gap separating the sensor from the thermally conductive material;
a heat shield coupled to an inferior broad end of the housing; and
a fan arranged in the housing cavity, wherein the housing and the fan cooperatively define a flow path between the air inlet and an air outlet.
2. The connected cooking appliance of claim 1 , wherein the heat shield fluidly isolates the housing cavity from the internal cooking cavity and optically connects the internal cooking cavity to the housing cavity.
3. The connected cooking appliance of claim 1 , wherein the sensor comprises an electromagnetic receiver.
4. The connected cooking appliance of claim 3 , wherein the sensor is an optical sensor having a field of view directed toward an inferior surface of the first internal cavity.
5. The connected cooking appliance of claim 4 , further comprising a lens arranged between the optical sensor and the heat shield.
6. The connected cooking appliance of claim 1 , wherein the heat shield is substantially transparent to a first regime of electromagnetic radiation wavelength and substantially opaque to a second portion of electromagnetic radiation wavelengths.
7. The connected cooking appliance of claim 1 , wherein the heat shield is configured to be aligned over an aperture defined by the superior surface defining the first internal cavity.
8. The connected cooking appliance of claim 1 , wherein the heat shield comprises an infrared coating arranged on an inferior broad surface of the heat shield.
9. The connected cooking appliance of claim 1 , wherein the flow path extends along a superior-inferior axis of the cooking appliance at the inlet or the outlet.
10. The connected cooking appliance of claim 9 , wherein the flow path defines substantially perpendicular directions of flow at the air inlet and the air outlet.
11. The connected cooking appliance of claim 1 , wherein the housing is operable in a set of configurations, the set of configurations comprising:
a coupled configuration, wherein the housing is coupled to the cooking appliance and arranged the internal cooking cavity second internal cavity of the cooking appliance, wherein the housing is configured to locate the sensor at the mounting point in the coupled configuration; and
an uncoupled configuration, wherein the housing is arranged outside the cooking appliance.
12. The connected cooking appliance of claim 11 , wherein transitioning between the coupled and uncoupled configurations comprises translating the housing along a superior-inferior axis.
13. The connected cooking appliance of claim 1 , wherein the housing further comprises a plurality of extended surfaces arranged along the flow path and thermally coupled to the thermally conductive material.
14. The connected cooking appliance of claim 13 , wherein the extended surfaces are thermally coupled to a light emitter, the light emitter defining an emission vector oriented towards the heat shield.
15. The connected cooking appliance of claim 1 , wherein the mounting point is a central point of a superior surface defining the internal cooking cavity.
16. The connected cooking appliance of claim 1 , wherein the sensor comprises a camera having a field of view directed toward an inferior surface of the first internal cavity and configured to sample a set of images of a superior surface of a food item arranged within the internal cooking cavity.
17. The connected cooking appliance of claim 1 , further comprising a wireless communication system within the housing and communicatively coupled to the sensor.
18. The connected cooking appliance of claim 1 , further comprising a processor communicatively within the housing and coupled to the sensor.
19. The connected cooking appliance of claim 1 , wherein the fan comprises an exhaust fan arranged proximal to the air outlet.
20. The connected cooking appliance of claim 1 , wherein the housing is configured to be selectively decoupled from the internal cooking cavity in response to satisfaction of a temperature threshold of the sensor.
