Title: An apparatus and method for deep fat frying
FIELD OF THE INVENTION
The present invention relates to the field of deep fat frying. In particular, the invention relates to the field of deep fat frying food products. More in particular, the invention relates to a deep fat fryer, a method for servicing a deep fat fryer, a method for disconnecting an electric heating element from a housing of a deep fat fryer and a method for powering an electric heating element of a deep fat fryer.
BACKGROUND
It is known to deep fry food products by dipping them in deep-frying fat and/or oil. As a result, on the outside of the food products a crispy crust can be formed. A deep fat fryer requires a user to add fat and/or oil, and to subsequently heat up the deep fat fryer prior to the deep-frying process. The fat and/or oil needs to have a high temperature of at least 100 degrees Celsius for deep fat frying. There are deep fat fryers available for at-home use, for use in catering industry, as well as industrial deep fat fryers.
For hygienic reasons, a deep fat fryer needs to be cleaned regularly. The cleaning can include replacing the fat and/or oil with fresh fat and/or oil. Prior to cleaning, the deep fat fryer is switched off and the parts of the deep fat fryer that are to be cleaned may need to have cooled due to safety reasons. Some parts of the deep fat fryer are not as easily reached by a service provider, such as a cleaner or maintenance person. For employees of restaurants, and in particular snackbars and cafés, cleaning of their deep fat frying apparatus causes undesired downtime of their deep-fryer. Particularly waiting for the deep fat fryer to have cooled is time consuming, wherein the employee often cannot meet catering consumer demand due to a diminished deep-frying capacity.
SUMMARY
It is an object to provide a deep fat fryer, a method for servicing, such as cleaning, a deep fat fryer, a method for disconnecting an electric heating element from a housing of a deep fat fryer and a method for powering an electric heating element of a deep fat fryer. More in general, it is an object to provide an improved deep fat fryer, and/or a method for handling/servicing a deep fat fryer.
Thereto, according to a first aspect is provided a deep fat fryer. The deep fat fryer comprises a housing. The housing can be manufactured from metal, such as stainless steel. The deep fat fryer comprises a cooking vessel mounted to the housing. The cooking vessel can at least partially be positioned in the housing. The cooking vessel can be integral with the housing. The deep fat fryer can comprise more than one cooking vessel, wherein the plurality of cooking vessels can be positioned, in e.g. a side-by-side arrangement, in the housing. The deep fat fryer comprises an electric heating element. The electric heating element can comprise a curved heat-conductor.
The deep fat fryer can comprise power control electronics, e.g. housed in the housing. The power control electronics can comprise one or more processors, a controller, communication circuitry, a power supply and/or a memory. One or more electrical components and/or circuits may perform some of or all the roles of the various components described herein. Although described separately, it is to be appreciated that electrical components need not be separate structural elements.
The power control electronics are configured for controlling and supplying electric power to the electric heating element. Programmable instructions may be stored in the power control electronics to execute algorithms for controlling and supplying electric power to the electric heating element.
The deep fat fryer comprises a first electric connector part and a second electric connector part. The first electric connector part is mounted to the housing and configured to be in electric connection with the power control electronics.
Alternatively, the first electric connector part can be integral with the housing.
The second electric connector part is configured for mating with the first electric connector part. Mating the electric connector parts can comprise engaging, e.g. using interlocking shapes, the first and second electric connector parts. The second electric connector part is mounted to the electric heating element for removably mechanically connecting the electric heating element to the housing and for removably electrically connecting the electric heating element to the power control electronics. Alternatively, the second electric connector part can be integral with the electric heating element. Removably connecting, i.e. mechanically and/or electrically, the electric heating element to the respective housing and/or power control electronics can comprise removably attaching the parts while a user is still capable of separating them. Removably connecting and separating can preferably be performed by a user using nothing but hand power or a hand tool. Removably connecting and separating can include overcoming a holding force between the first and second connector part, wherein the holding force can be overcome by use of hand power or a hand tool. The first and/or second electric connector part can comprise securing means for removably mechanically and/or electrically connecting the electric heating element to the respective housing and/or power control electronics.
The deep fat fryer can be a stand-alone deep fat fryer. The housing of the stand-alone deep fat fryer can be configured such that the stand-alone deep fat fryer can be positioned and operated in a work place, such as a restaurant kitchen, without further modification to the deep fat fryer and/or the work place. The housing of the stand-alone deep fat fryer can be configured such that the housing shields a user from internal parts of the deep fat fryer, such as potentially dangerous electric or electronic components.
The deep fat fryer can be a so-called drop-in deep fat fryer. De drop-in deep fat fryer is configured to be installed into a countertop. Hence, the housing of the drop-in deep fat fryer can be a partial housing configured such that the housing shields a user from internal parts of the deep fat fryer, such as potentially dangerous electric or electronic components, only after installation into the countertop. The installation into the countertop can e.g. include welding the housing of the deep fat fryer to the countertop, e.g. into an aperture in the countertop.
Optionally, the first electric connector part comprises two first power contacts and the second electric connector part comprises two second power contacts. The first and second electric power contacts are configured for, when the first and second connector part are connected, conducting electric power for powering the electric heating element to the electric heating element. There can be more than two first power contacts in the first electric connector part. Similarly, the second electric connector part can comprise more than two second power contacts. For instance the first electric connector part comprises three or four first power contacts and the second electric connector part comprises three or four second power contacts, e.g. for using two or three phase AC power. The number of first power contacts is preferably equal to the number of second power contacts.
The first power contacts can be electrically connected to the power control electronics. When the first and second connector part are connected, the first and second power contacts can be in electrically conducting engagement for allowing electric power transfer therebetween for powering the electric heating element.
The electric power for powering the electric heating element can be supplied to the electric heating element by the power control electronics when the first and second connector part are connected.
Optionally, the deep fat fryer comprises a detector for detecting that the first and second connector part are connected. The detector can be positioned integral with the power control electronics.
Optionally, the detector is configured for detecting that the first and second power contacts are in electrically conducting engagement.
Optionally, the power control electronics are configured for supplying electric power for powering the electric heating element to the first power contacts if the detector detects that the first and second power contacts are in electrically conducting engagement. The power control electronics can be configured for refraining from supplying electric power for powering the electric heating element to the first power contacts if the detector detects that the first and second power contacts are not in electrically conducting engagement. Thus, it can be avoided that electric power for powering the electric heating element is supplied to the first power contacts while the second power contacts are not in electrically conducting engagement with the first electric power contacts yet. Hence, electric arcing, e.g. during mating of the first and second electric connector parts, can be avoided.
Optionally, the power control electronics are configured for detecting that the first and second power contacts are in electrically conducting engagement on the basis of measurement of an electric parameter at one or all of the first power contacts. The electric parameter can e.g. comprise current, voltage and/or electric 5 resistance.
Optionally, an electric signal can be provided to at least one of the first power contacts for detecting whether the first and second power contacts are in an electrically conducting engagement. A power or a voltage of the electric signal can be lower than electric power or voltage for powering the electric heating element.
When the power control electronics refrain from supplying electric power for powering the electric heating element to the first power contacts the electric signal can nevertheless be supplied to the first power contacts to detect whether the first and second power contacts are electrically connected. The electric signal preferably has a power and/or voltage insufficient for powering the electric heating element.
A power of the electric signal can e.g. be less than 10% of the power rating of the electric heating element. A voltage of the electric signal can be lower than the voltage for powering the electric heating element. The electric heating element can e.g. be rated for powering at 400V. The electric signal can e.g. have a voltage of 100V or less, preferably 48V or less, such as 24V or less. The low power and/or low voltage electric signal, or a signal representative thereof, can e.g. be detected, when the first and second power contacts are in electrically conducting engagement, by the detector directly or by the detector via the power control electronics.
Optionally, the detector is part of the first electric connector part. The detector can be electrically connected to the first power contacts. The detector can be positioned between two or more of the first power contacts.
Optionally, the first electric connector part comprises two first sensing contacts and the second electric connector part comprises two second sensing contacts for, when the first and second connector part are connected, detecting that the first and second connector part are connected. The first sensing contacts can be electrically connected to the power control electronics.

Optionally, the deep fat fryer is configured for detecting that the first and second connector part are connected if the first and second sensing contacts are in an electrically conducting engagement. The electric signal, or a signal representative thereof, can be detected, when the first and second sensing contacts are in electrically conducting engagement. The electric signal can be supplied to the first sensing contacts by the power control electronics for detecting that the first and second sensing contacts are electrically connected.
Optionally, when the power control electronics refrain from supplying electric power for powering the electric heating element to the first power contacts, the electrical signal can be transferred to the first sensing contacts to detect whether the first and second sensing contacts are electrically connected.
Optionally, the first power contacts comprise conducting sockets and the second power contacts comprise conducting pens.

At least one of the pens of the second power contacts can be longer than the pens of the second sensing contacts. Thus, while mating the first electric connector part and the second electric connector part, when the first and second sensing contacts allow detection of the electric signal the first and second power contacts are already in electrically conducting engagement, and electric power for powering the electric heating element can safely be activated.
Optionally, the detector comprises an optical detector configured for detecting a connected position of the first and second connector part. The optical detector can comprise a Light-Emitting Diode (LED) and a light detector. The LED and light detector can be mounted in, e.g. a recessed part of, the first electric connector part. The optical detector can comprise a vane mounted in the second electric connector part. When the first and second connector parts are disconnected, the light detector can detect at least part of the light emitted by the
LED. When the first and second connector parts are connected, the vane can block at least part of the light, such that the light detector can detect substantially no light emitted by the LED. The optical detector can be positioned such that detecting that the first and second connector part are connected implies that the first and second power contacts are in electrically conducting engagement.
Optionally, the detector comprises a mechanical detector, such as a switch, configured for detecting a connected position of the first and second connector part. The mechanical detector can be positioned in, e.g. a recessed parts of, the first electric connector part, e.g. at a proximal end thereof. The mechanical detector can also comprise a protrusion of the second electric connector part. When the first and second connector parts are disconnected, the mechanical detector can be in the neutral position. When the first and second connector parts are connected, the mechanical detector can be in the activated position, e.g. by the protrusion pressing against the mechanical detector part, e.g. the switch, of the first connector part. The mechanical detector can be positioned such that detecting that the first and second connector part are connected implies that the first and second power contacts are in electrically conducting engagement.
Optionally, the detector comprises an inductive, capacitive, and/or magnetic detector, configured for detecting a connected position of the first and second connector part.

DETAILED DESCRIPTION
Figure 1 shows an illustration of a schematic representation of an example of a cross section of a side view of a deep fat fryer 1, wherein the electric heating element 6 and the housing 2 are connected. The deep fat fryer 1 comprises a housing 2, a cooking vessel 4, an electric heating element 6 and power control electronics 8. The deep fat fryer 1 further comprises a first electric connector part 10 and a second electric connector part 12. The cooking vessel 4 is mounted to the housing 2. The power control electronics 8 are positioned in the housing 2, and configured for controlling and supplying electric power to the electric heating element 6. The first electric connector part 10 is mounted to the housing 2 and in electric connection with the power control electronics 8. Here, the electric connection between the first electric connector part 10 and the power control electronics 8 comprises a power supply wiring 11 and optionally a sensing wiring 13.
The second electric connector part 12 is mounted to the electric heating element 6. The first and second electric connector parts 10,12 are configured for mating with each other. In Figure 1, the second electric connector part 12 is connected to the first electric connector part 10. The second electric connector part 12 is configured for removably mechanically connecting the electric heating element 6 to the housing 2 and for removably electrically connecting the electric heating element 6 to the power control electronics 8.
The deep fat fryer 1 in this example comprises a detector 15 for detecting that the first and second connector part 10,12 are connected. The detector 15 is in this example positioned integral with the power control electronics 8 in the housing 2. It will be appreciated that the detector 15 can alternatively be positioned in the housing 2 outside of the power control electronics 8, or the detector 15 can be positioned in the first electric connector part 10. In this example, the detector 15 1s connected to the power supply wiring 11 and the power control electronics 8, and optionally to the sensing wiring 13. The power control electronics 8 can then be configured for supplying electric power for powering the electric heating element 6 if the detector 15 detects that the first and second electric connector parts 10,12 are in an electrically conducting engagement. The power control electronics 8 can be configured for refraining from supplying electric power for powering the electric heating element 6 to power control electronics 8 if the detector 15 detects that the first and second electric connector parts 10,12 are not in electrically conducting engagement.
Figure 2 shows an illustration of a schematic representation of an example of a side view of a cross section of a deep fat fryer 1, wherein the electric heating element 6 and the housing 2 are disconnected. In this Figure 2, the second electric connector part 12 is disconnected from the first electric connector part 10.
Here, the first electric connector part 10 comprises two first power contacts 14 and the second electric connector part 12 comprises two second power contacts 16. The first electric connector part 10 comprises two first sensing contacts 18 and the second electric connector part 12 comprises two second sensing contacts 20 1n this example. It will be appreciated that the first and second electric connector parts 10,12 can each comprise more than two respective first and second power contacts 14,16 and/or more than two respective first and second sensing contacts 18,20. The number of first sensing contacts 18 can be equal to the number of second sensing contacts 20. The number of first power contacts 14 can be equal to the number of second power contacts 16. The first and second power contacts 14,16 are configured for, when the first and second connector part 10,12 are connected, conducting electric power for powering the electric heating element 6 to the power control electronics 8 vla power supply wiring 11. Here, the first and second sensing contacts 18,20 are configured for, when the first and second connector part 10,12 are connected, detecting that the first and second connector part 10,12 are connected, e.g. via the sensing wiring 13. Here, the first and second sensing contacts 18,20 are configured for detecting that the first and second power contacts 14,16 are in an electrically conducting engagement. The deep fat fryer 1 is in this example configured for detecting that the first and second connector part 10,12 are connected if the first and second sensing contacts 18,20 are in an electrically conducting engagement.
In this example, the deep fat fryer 1 comprises a detachable handle 22 for selectively removing the electric heating element 6 from the housing 2. Here, the detachable handle 22 comprises a distal part 24 for engaging the electric heating element 6 and/or the second connector part 12. The detachable handle 22 in this example comprises a proximal part 26 for holding the detachable handle 22 by a user. The proximal part 26 is preferably not thermally-conductive, such that the detachable handle 22 can be used while the electric heating element 6 is still hot.
The first power contacts 14 and first sensing contacts 18 in this example comprise conducting sockets in the first electric connector part 10. The second power contacts 16 and the second sensing contacts 20 in this example comprise conducting pens on the second electric connector part 12. The conducting pens and sockets are in this example positioned such that, when mating the first and second electric connector parts 10,12, the pens and sockets of the first and second power contacts 14,16 are at least partially in mechanical engagement with each other prior to the pens and sockets of the first and second sensing contacts 18,20 are in mechanical engagement with each other. Here, the conducting pens and sockets are also positioned such that, when mating the first and second electric connector parts 10,12, the pens and sockets of the first and second sensing contacts 18,20 are in electrically conducting engagement with each other prior to the pens and sockets of the first and second power contacts 14,16 are in electrically conducting engagement with each other. Here, the conducting pens of the second power contacts 16 are longer than the conducting pens of the second sensing contacts 20.
The deep fat fryer 1 in this example comprises a detector 15 for detecting that the first and second connector part 10,12 are connected. Here, the detector 15 is configured for detecting that the first and second power contacts 14,16 are in electrically conducting engagement. The detector 15 is in this example positioned integral with the power control electronics 8 in the housing 2. It will be appreciated that the detector 15 can alternatively be positioned in the housing 2 outside of the power control electronics 8, or the detector 15 can be positioned in the first electric connector part 10.
The second sensing contacts 20 can, in the second connector part or in the electric heating element, e.g. be electrically connected via a circuit 17, such as a short, a resistor or the like. By supplying an electric signal to at least one of the first sensing contacts 18, and detecting a resulting electric signal at at least one of the first sensing contacts, it can be detected whether the first sensing contacts 18 are in contact with the circuit via the second sensing contacts 20, or not. The detector 15 can e.g. determine a current flowing through the sensing wiring 11, a voltage at one or more of the sensing contacts 20, a resistance measured across the sensing contacts 20, or the like, representative of the first and second sensing contacts 18,20 being in electrically conducting engagement. Hence, it can be detected whether the first connector part is connected to the second connector part or not. Since in this example the conducting pens and sockets are also positioned such that, when mating the first and second electric connector parts 10,12, the pens and sockets of the first and second sensing contacts 18,20 are in electrically conducting engagement with each other prior to the pens and sockets of the first and second power contacts 14,16 are in electrically conducting engagement with each other, it applies that while mating the first electric connector part 10 and the second electric connector part 12 the first and second sensing contacts 18,20 first allow detection of the resulting electric signal while the first and second power contacts 14,16 are already in electrically conducting engagement. Hence, electric power for powering the electric heating element can safely be activated upon detection of the resulting electric signal.
The power control electronics 8 can thus be configured for supplying electric power for powering the electric heating element 6 to the first power contacts 14 if the detector 15 detects that the first and second power contacts 14,16 are in electrically conducting engagement. The power control electronics 8 can be configured for refraining from supplying electric power for powering the electric heating element 6 to the first power contacts 14,16 if the detector 15 detects that the first and second power contacts 14,16 are not in electrically conducting engagement.
In an alternative example, the detector 15 can be positioned in contact with the first and/or second power contacts 14,16. In such case the sensing contacts 18,20 and sensing wiring 12 may be omitted if desired. An electric signal can then be provided to at least one of the first power contacts 14 for detecting whether the first and second power contacts 14,16 are in an electrically conducting engagement.
A power or a voltage of the electric signal can be lower than electric power or voltage for powering the electric heating element 6. When the power control electronics 8 refrain from supplying electric power for powering the electric heating element 6 to the first power contacts 14, the electric signal can nevertheless be supplied to the first power contacts 14 to detect whether the first and second power contacts 14,16 are electrically connected. In this example, the electric signal has a power and/or voltage insufficient for powering the electric heating element. A power of the electric signal can e.g. be less than 10% of the power rating of the electric heating element. A voltage of the electric signal can be lower than the voltage for powering the electric heating element. The electric heating element can e.g. be rated for powering at 400V. The electric signal can e.g. have a voltage of 100V or less, preferably 48V or less, such as 24V or less. The low power and/or low voltage electric signal, or a signal representative thereof, can e.g. be detected, when the first and second power contacts are in electrically conducting engagement.
