Description

DETAILED DESCRIPTION OF THE INVENTION

[0017] The inventive deep fryer with external wall heating shall be evaluated according to the following figures in order to better understand the improvements made for reaching the abovementioned aims.

[0018] In these figures;

[0019] FIG. 1 is a general view of the heating system of the deep fryer

[0020] FIG. 2 is a sectional view of the reservoir

[0021] FIG. 3 is a detailed view of the wave breaker

[0022] FIG. 4 is an exploded view of the external structure of the heating system of the deep fryer

[0023] Numbers are put on the figures in order to make the inventive deep fryer with external wall heating to be understood better. Accordingly; [0024] 1. Reservoir [0025] 2. Resistance [0026] 3. Heat sensor [0027] 4. Microprocessor [0028] 5. Wave breaker [0029] 6. Cold reservoir [0030] 7. Insulation material [0031] 8. Insulation sheath

[0032] The production of the reservoir (1) included in the deep fryer designed for the invention is made from cast material. The reservoir (1) produced from cast material can be heated within a short period of time and the reservoir (1) can disperse its heat to the surface homogenously. A resistance (2) is installed on each of the four sides of the reservoir (1) from its external surfaces. The resistances (2) which are fastened to the external sides of the chamber (1) do not burn the oil, since they do not directly contact with the oil. Furthermore, in the R&D tests performed by way of mounting the resistances (2) on the external side of the reservoir (1), since the surface area expands, it is seen that the required temperatures are reached within a short period of time and the energy is saved. (FIG. 2)

[0033] The insulation material (7) which covers the periphery of the reservoir (1) is another aspect which helps energy saving in the deep fryer designed for the invention. The insulation material (1) helps with transferring all the heat provided by the resistance (2) to the reservoir (1). The insulation material (7) that covers the external portion of the resistance (2) is surrounded by an insulation sheath (8) as seen in FIG. 4. The insulation sheath (8) provides the used insulation material (7) to remain stable around the resistance (2).

[0034] The heat sensor (3) located on the internal surface of the reservoir (1) is a sensor which has a sensitivity of one tenth of a degree. The heat sensor (3) which is compatible with the computers is connected with the microprocessor (4). The heat sensor (3) is an advanced technological product which can transfer very sensitive and instant values to the microprocessor (4). The heat sensor (3) transfers the instant temperature data of the oil within the reservoir (1) to the microprocessor (4) six times a second with a sensitivity of one tenth of a degree. (FIG. 1)

[0035] The microprocessor (4) controls the resistances (2) via the data received from the heat sensor (3). It manages the resistances (2) by means of the software created for microprocessor (4), it makes the most optimal oil temperature and energy consumption possible in any case. The resistances (2) that are not required to operate can be turned off by means of the software of the microprocessor (4) by considering the data of the oil temperature received from the heat sensor (2).

[0036] There is a cold reservoir (6) formed at the lower portion of the reservoir (1). The cold reservoir (6) is a secondary reservoir contained in the deep fryer. The particles (breaded, small particles, flour, crumbs etc.) of the food which is cooked in the reservoir (1) pass to the cold chamber (6) located at the lower portion of the reservoir (1). There is warm oil in the cold reservoir (6) in contrast to the reservoir (1). The food particles trapped in the cold reservoir (6) are prevented from burning within the oil and the quality of the oil is protected. The cold reservoir (6) may have preferably a conical shape but also may have another geometric shape.

[0037] In the R&D test studies realized in the inventive designed deep fryer, when the cooking basket of the fryer is immersed into the reservoir (1), the hot oil remains in the upper/middle portion of the reservoir (1) creates turbulence within the reservoir by ascending and descending up/down with circular movements. This condition causes mixture of the hot oil within the reservoir (1) and the warm oil within the cold reservoir (6) placed below. Therefore, the oil which is at the upper portion and is required to be hot cools down and affects the cooking ability of the deep fryer negatively. In addition to this, it places the food particles passed in the cold reservoir (6) into the reservoir (1) section and this causes negative consequences as they are burnt in the hot oil. A wave breaker (5) is positioned between the reservoir (1) and the cold reservoir (6) so as to solve this technical problem. The wave breaker (5) in FIG. 3 prevents the mixture of the warm oil within the cold reservoir (6) located at the lower portion of the deep fryer and the hot oil within the reservoir (1) at the upper portion. It is observed that the optimum results in the R&D studies performed are achieved when the wave breaker (5) model is with a grid-structure. The wave breaker (5) that prevents the mixture of the warm and hot oil to each other protects the food cooking ability of the deep fryer. Moreover, it helps the food particles that fall into the cold reservoir (6) to remain within the cold reservoir (6).
