Blender with temperature sensor
The invention relates to a blender ( 10 ) for blending ingredients. The blender ( 10 ) comprises a base part ( 11 ) comprising a heating plate ( 22 ), and a container ( 13 ) for receiving said ingredients. The container ( 13 ) is detachable from the base part ( 11 ) and comprising a bottom part for contacting the heating plate ( 22 ). The base part ( 11 ) comprises a temperature sensor ( 23 ) for sensing the temperature of the bottom part. The temperature sensor ( 23 ) extends tends through the heating plate ( 22 ).
1. A blender for blending ingredients, said blender comprising:
a base part including a motor therein, said
base part comprising:
a heating plate comprising:
a heating element extending along a portion of a circumference of the heating plate;
a first contact connected to a first end of the heating element; and
a second contact connected to a second end of the heating element;
a first opening substantially centered within the heating plate and a second opening positioned between the first end and the second end of the heating element and offset from the first opening; and
a temperature sensor extending through said second opening; and
a container, detachable from said base part, said container comprising
a first container opening configured to receive said ingredients; and a
bottom part, including a rotatable blade assembly extending through the bottom part configured to engage said motor, said bottom part configured to:
contact the heating plate; and the temperature sensor.
2. The blender as claimed in claim 1 , wherein said temperature sensor comprises a thermistor.
3. The blender as claimed in claim 2 , wherein said thermistor is a Negative Temperature Coefficient thermistor.
4. The blender as claimed in claim 2 , wherein said temperature sensor comprises a cap encapsulating said thermistor.
5. The blender as claimed in claim 4 , wherein said cap is made of a high temperature resistant material.
6. The blender as claimed in claim 4 , wherein said cap is cylindrical-shaped.
7. The blender as claimed in claim 4 , wherein said heating plate comprises an aperture for receiving said cap.
8. The blender as claimed in claim 4 , wherein said second opening and said cap are dimensioned to create an air gap in-between.
9. The blender as claimed in claim 4 , wherein said cap is movable along a vertical direction (D) relative to the heating plate, said cap being configured to take a first position (P 1 ) when said bottom part does not contact said heating plate, and a second position (P 2 ) when said bottom part contacts said heating plate.
10. The blender as claimed in claim 9 , wherein said given distance is in the range 1 mm to 10 mm.
11. The blender as claimed in claim 9 , wherein said cap is biased toward said first position (P 1 ).
12. The blender as claimed in claim 9 , wherein said thermistor is in contact with said flat top part.
13. The blender as claimed in claim 9 , wherein said cap comprising a flat top part, said flat top part coming out by a given distance from an external surface of said heating plate in said first position (P 1 ), said flat top part being aligned with said external surface in said second position (P 2 ).
