Abstract

In a table mountable fryer according to the present invention, a frying vessel which contains water and oil in a state where an oil layer is formed on a water layer due to a difference in their specific gravities is installed at the center of a table. The fryer comprises a heater installed in the frying vessel for heating the oil layer, a water level sensor installed at a predetermined position below the heater in the frying vessel for detecting an interface between the water and oil layers, and an oil layer heating control means connected to the water level sensor for stopping heating the oil layer by the heater in response to the detection of the interface by the water level sensor.

Therefore, a general user other than a cook can take a meal and drink beverages while safely and freely cooking fries at table by installing the frying vessel, which has the oil layer and the water layer therein at the upper and lower portions, respectively, at the center of the table. Oxidization of the oil layer can be prohibited and deterioration of the oil layer or generation of oil fumes due to fry remnants or burned remnants can be prevented. Moreover, even the general user who does not know discharge timing of the water depending on the amount of cooked fries can easily and safely utilize the fryer.

Claims

1. A table mountable fryer, wherein a frying vessel is installed at the center of a table and contains oil and water at upper and lower portions thereof and heating of the oil is controlled by detecting a position of an interface between the oil and the water.

2. The fryer as claimed in claim 1, comprising the frying vessel in which an oil layer is formed on a water layer due to a difference in their specific gravities;

a heater installed in the middle of the frying vessel for heating the oil layer;

a cooling pipe installed below the heater for cooling a portion of the oil layer below the heater;

a first water level sensor installed at a predetermined position below the heater for detecting the interface between the water and oil layers; and

an oil layer heating control means for stopping heating the oil layer by the heater in response to the output of the first water level sensor.

3. The fryer as claimed in claim 2, further comprising a second water level sensor installed at a predetermined position below the first water level sensor to detect the interface between the oil and water layers, wherein the oil layer heating control means includes a means for starting again heating the oil layer by the heater upon detection of the interface by the second water level sensor after the detection of the interface by the first water level sensor.

4. The fryer as claimed in claim 2, further comprising a means for issuing a warning signal indicating that the interface has been raised, when the first water level sensor detects the interface.

5. The fryer as claimed in claim 3, further comprising a means for displaying a signal indicating that a water level is at a safe position upon detection of the interface by the second water level sensor.

6. The fryer as claimed in claim 2, wherein the frying vessel is V-shaped in cross section at the lower portion thereof, one lateral side of the lower portion of the frying vessel is inclined downward, and a water discharge valve is installed at an end of the lateral side.

7. The fryer as claimed in claim 4, further comprising a means for lowering a water level by operating a water discharge valve installed at a lower end of the frying vessel upon issue of the warning signal indicating that the interface has been raised.

8. The fryer as claimed in claim 7, further comprising a means for displaying a signal indicating that the water level has been exceedingly lowered, upon detection of lowering of the interface below the second water level sensor.
