Summary of the Invention

Problems to be Solved by the Invention

[0005] In the two - layer fryer 1 of this conventional example, in order to discharge fried scraps 5 and the like to the outside together with the drainage 8 by the water filtration system, water is supplied regularly. Also, water is supplied regularly to lower the temperature of the rising water. Alternatively, during frying, since oil is taken out by the food ingredients, the amount of oil decreases and the amount of water increases. For these reasons, when the water increases and the interface line 12 rises, the water approaches the heater and becomes hot. When it further boils, the oil will spurt out. Also, there is a problem that there is a risk of explosion when the boiling point is reached.

[0006] Therefore, in the two - layer fryer 1 in the conventional example, there is a problem that must be solved by providing some system for stopping the heating before the interface line 12 rises, the water approaches the heater, becomes hot, boils, and the oil spurts out.

Means for Solving the Problems

[0007] The gist of the present invention for solving the problems of the above - mentioned conventional example is a water safety sensor for a fryer in a two - layer fryer in which water and oil are stored in a cooking tank, a water layer is formed on the lower side, and an oil layer is formed on the upper side. The water safety sensor is installed on the oil - layer side near the interface line between the water layer and the oil layer. When the water in the cooking tank increases, the interface line rises and the water comes into contact, it detects and stops the heating of the fryer. And when it cannot detect the contact with the water, it detects a preset predetermined water temperature and stops the heating of the fryer.

[0008] Also, the water safety sensor is provided so as to be visually recognizable together with the interface line between the water layer and the oil layer through a window provided outside the cooking tank; The detection position of the water safety sensor is line - displayed on a window provided outside the cooking tank; which includes the above.

Effects of the Invention

[0009] According to the water safety sensor of the fryer according to the present invention, when the water in the cooking tank increases and the interface line rises and comes into contact with the water, it is configured to detect this and stop the heating of the fryer, thereby preventing in advance an accident in which the water becomes high temperature, boils, and the oil spurts out. Furthermore, when an oil film or the like adheres to the sensor detection part due to poor cleaning or the like and the contact with water cannot be detected, the heating of the fryer is stopped by detecting a preset predetermined water temperature. That is, the water safety sensor also serves as a water detection sensor and a temperature detection sensor, and is equipped with a double safety device, achieving an excellent effect of improving safety.

[0010] The water safety sensor is provided so as to be visible together with the interface line between the water layer and the oil layer through a window provided outside the cooking tank. When the interface line in the cooking tank rises and comes into contact with the water, an excellent effect is achieved in that the process of stopping the heating of the fryer can be visually recognized.

[0011] The detection position of the water safety sensor is line-displayed on a window provided outside the cooking tank, achieving an excellent effect in that the process in which the interface line in the cooking tank rises and comes into contact with the water can be clearly recognized.

Modes for Carrying Out the Invention

[0013] Next, embodiments of the present invention will be described in detail with reference to the drawings. For ease of understanding, the parts corresponding to the drawings (see FIG. 5) described in the conventional example are denoted by the same reference numerals as in the conventional example and will be described.

Example

[0014] As shown in FIGS. 1 and 2, the present invention is a water safety sensor 25 for a fryer in a two-layer fryer 21 in which water and oil are stored in a cooking tank 22, a water layer 4 is formed on the lower side, and an oil layer 3 is formed on the upper side. As shown in FIG. 2, there is an interface line 26 between the water layer 4 and the oil layer 3, and the interface line 26 moves up and down appropriately according to the increase or decrease of water or oil.

[0015] The two-layer fryer 21 is the same as in the case described in the conventional example (see FIG. 5), water and oil are stored inside the cooking tank 22, an oil layer 3 is formed on the upper side, and a water layer 4 is formed on the lower side. During frying, fried scraps 5, oxides, etc. are dropped from the oil layer 3 to the water layer 4, collected in the draft box 6, and the collected fried scraps 5, etc. are discharged together with the drainage 8 through the drain pipe 7 (see FIGS. 1 and 5).

[0016] A conveyor 9 is provided below the foodstuff input part 10 in the cooking tank 22, the input foodstuff is moved by the conveyor 9, and the fried foodstuff is continuously discharged from the discharge part 11 (see FIGS. 1 and 5). As shown in FIGS. 1 and 2, a window part 27 is provided on the front side of the cooking tank 22, and the water safety sensor 25 is visible from the window part 27. Further, the detection position 32 of the water safety sensor 25 is line-displayed on the window part 27. The water safety sensor 25 will be described later.

Example

[0017] FIG. 3 is a front view of a two-layer fryer 28 of another embodiment provided with the water safety sensor according to the present invention, and FIG. 4 is a front view showing an enlarged view of a window portion 30 provided outside the cooking tank 29.

[0018] Unlike the case of the first embodiment, the two-layer fryer 28 is of a type that does not have a conveyor 9, and the fried food is pulled upward in a state of being stored in a bucket (not shown). As shown in FIGS. 3 and 4, a window portion 30 is provided on the front side of the cooking tank 29, and the water safety sensor 25 is visible through the window portion 30. Further, the detection position 32 of the water safety sensor 25 is line-displayed on the window portion 30.

[0019] The two-layer fryer 28 is the same as that described in the conventional example (see FIG. 5), has a portion for storing water and oil inside the cooking tank 29 and forming an oil layer 3 at the upper part, and a portion for forming a water layer 4 at the lower part (see FIGS. 4 and 5). During frying, fried scraps 5, oxides, etc. are dropped from the portion where the oil layer 3 is formed to the portion where the water layer 4 is formed, collected in the draft box 6, and the collected fried scraps 5, etc. are discharged together with the drainage 8 through the drain pipe 7 (see FIGS. 4 and 5).

[0020] As shown in FIG. 4, there is an interface line 26 between the water layer 4 and the oil layer 3, and the interface line 26 moves up and down appropriately according to the increase or decrease of water or oil.

[0021] Next, the water safety sensor 25 shown in FIGS. 2 and 4 will be described. First, the water safety sensor 25 has a function as a water detection sensor. That is, when the interface line 26 in the cooking tanks 22, 29 rises and contacts water, it detects this and sends a signal to a control unit (not shown) to stop the heating of the fryer. Therefore, it is possible to prevent an accident in which water becomes hot and boils and oil spurts out.

[0022] Furthermore, the water safety sensor 25 has the function as a temperature sensing sensor. That is, when an oil film or the like adheres to the sensor sensing part due to poor cleaning or the like and water contact cannot be sensed, a predetermined water temperature is detected and a signal is transmitted to a control part (not shown) to stop the heating of the fryer. Therefore, the water safety sensor 25 serves as both a water sensing sensor and a temperature sensing sensor, equipped with a dual safety device, and the safety is improved.

[0023] Next, the mechanism of the water safety sensor 25 as a temperature sensing sensor will be described. First, when the heater is operating, the detected temperature (initial set temperature 25°C) is compared with the current temperature + 2°C, and the lower temperature is set as the water detection temperature. This is the result considering the period when the water temperature is low in winter and the period when the water temperature is high in summer. And after reaching the water detection start temperature (initial set temperature 60°C), the flag is raised and the detection starts. After the detection starts, when the water safety sensor 25 detects a temperature lower than the above-mentioned water detection temperature, it is determined that water has come into contact, and a signal is transmitted to a control part (not shown) to stop the heating of the fryer.

[0024] The water safety sensor 25 is provided so as to be visually recognizable together with the interface line 26 between the water layer 4 and the oil layer 3 from the window parts 27, 30 provided outside the cooking tanks 22, 29. Therefore, when the interface line 26 in the cooking tanks 22, 29 rises and comes into contact with water, the process of stopping the heating of the fryer can be visually confirmed. Note that the reference numeral 31 in FIGS. 2 and 4 indicates a drain pipe for waste oil.

[0025] Also, the detection position 32 of the water safety sensor 25 is line - indicated on the window parts 27, 30 provided outside the cooking tanks 22, 29. Therefore, the process of the interface line in the cooking tanks 22, 29 rising and coming into contact with water can be clearly recognized.
